The adjustment of the brightness of the field of view under the visual microscope lens was mainly related to the mirror and the shutter. The aperture and the mirror were used together to ensure the best light required. The adjustment steps were as follows: Move the revolver with your thumb and middle finger (do not move the objective lens with your hand), so that the low-power lens was aimed at the light hole of the mirror table (when you hear the knocking sound, it means that the optical axis of the objective lens has been aligned with the center of the tube). Open the aperture, raise the light collector, and turn the mirror to the light source. Observe with the left eye on the eyepieces (open the right eye). At the same time, adjust the direction of the mirror until the light in the field of vision is evenly bright. The size of the aperture could also be changed by adjusting the shutter. When the field of vision was bright, a large aperture was used, and when the field of vision was dark, a small aperture was used. As for the mirror, a concave mirror was used when it was bright, and a flat mirror was used when it was dark. Read more exciting novels for free

How Did I Become an F1 Driver?

How Did I Become an F1 Driver?

How did I become an F1 driver? Qin Miao discovered that he had the talent to become a top e-sports driver. Just during the college entrance examination period, he played with the simulator in his spare time and was surprised to find that he had the ability to compete with other professional e-sports drivers. You should know that he just played casually and had this ability. If he settled down to practice, Qin Miao would definitely have a bright future on the road of e-sports drivers. Qin Miao was ready to take the path of an e-sports driver if he failed the college entrance examination. But on a very ordinary day, Qin Miao gained a system. However, Qin Miao was still sensible. Even if he got the system, it was unlikely for him to become a formal F1 driver. Because when he got the system, he was already 19 years old and hadn't been exposed to anything related to racing before the age of 19. Two years later: Xiaozhou: There is no doubt that Qin Miao is a very talented driver, but I feel that racing is just a profession for him, his real hobby is live streaming and playing games. Lock: Qin? Just a second-generation Kimi. But then again, he plays CSGO really well, it was he who boosted my Earth. Old Man: Qin is a pure person, his life is only about racing... and video games. Dutch White-eyed Wolf: I have nothing to say about him. Bi Hai: If he spent half the time he uses to play games on the simulator, his achievements now would be far beyond this! Horner: I really appreciate Qin, he is a natural-born F1 driver and also a pure person, I very much hope he can join Red Bull and become one of us.

How to adjust the brightness with a single-lens reflex camera

Different brands of DSLR cameras adjusted the brightness in different ways. For Canon single-lens reflex cameras, you can press the menu button on the top left corner of the screen to switch to the menu bar marked with a wrench. Then, you can find the [LCD Brightness] option and enter the LCD brightness setting. You can change the brightness setting from (Automatic) to (Manual) to adjust the brightness accordingly. You can also adjust the overall brightness of the screen by adjusting the sensitivity (adjust the sensitivity below 800) and the shutter time (the shutter is measured in seconds. The longer the shutter time, the brighter the image will be). For Nikon single-lens reflex cameras: Press the MENU key and select the setting menu.(Shaped like a small wrench option), which can be used to select the brightness of the LCD display, press the down arrow or up arrow; You can also use the exposure compensation button to adjust the darkness or brightness of the photo without changing the shutter and aperture; the USB sensitivity button can adjust the camera sensitivity to change the brightness of the picture; If the camera can't autofocus in a dark environment, you can use a light source as a guide, press the shutter halfway to lock the focus point and then turn off the light source, or directly use manual focus. In the basic shooting area of some single-lens reflex cameras, the camera would automatically set the sensitivity. In the creative shooting area, to adjust the sensitivity of the camera, you could press the USB button, look at the screen, and turn the dial or dial to adjust. In a dark environment at night, a combination of high sensitivity and exposure compensation could be used. In addition, you can also adjust the brightness in the image quality adjustment parameters to change the brightness of the middle tone of the picture. For example, in natural scenery photography, adjust the brightness to-0.5 to 1.5, and you can get different picture effects while maintaining the same exposure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Microscope lens modification photography

There were many ways to modify a microscope lens for photography. For example, a microscope lens could be modified into a camera lens for shooting, but this modification needed further improvement. There were also people who used the Hikvision camera and microscope lens to modify the electron microscope, but they might encounter some problems during the modification process. For example, the image was unclear, which might be a problem with the camera. When modifying, they had to consider the compatibility of the lens and the equipment. For example, when combining the microscope lens with the Hikvision network camera, they had to solve problems such as sensors, equipment errors, video storage, and so on. It may require the assistance of software such as the computer video recording software, the IVS- 4200. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Microscope objective lens parameters

The parameters of the microscope objective lens mainly included the following aspects: 1. ** Magnification **: It can be divided into low-power objectives (such as 2x, 4x/5x, and 10x), medium-power objectives (such as 20x, 40x), and high-power objectives (such as 60x/63x, 100x). Different magnifying lenses used different media. High power lenses (60x and 100x) often used oil to obtain high resolution, while lenses with lower magnifying powers used air as the medium. 2. ** Observation method **: There are many types of microscope objectives. The common observation methods marked on the lens shell are: FF (bright-field), TF (dark-field), PL (phase contrast), Po (polar light), DIC (differential interference), FF (fluorescence observation, such as blue, green, purple, etc.), UVFO (ultraviolet-fluorescence observation), etc. 3. ** Chromatic Deviation correction ability **: - Achromatic objective lens: It can only correct the color difference of red and blue light. - Semiapochromatic objective (TL): Able to correct the color difference of red, green, and blue light. - Apoachromatic objective lens (Apo): It can correct the color difference of red, green and blue light twice, and can correct the spherical aberrations of red and blue light at the same time. 4. ** Flat-field correction function **: Choose an objective lens with flat-field correction function (marked with Plan) for better imaging effect. For example, a flat-field achromatic objective (Ach) could be used to view transparent sections; a semi-apochromatic objective (TL) could be used to view fluorescence, which had a long working distance and could be used to observe glass slips and petri dishes; a full-apochromatic objective (Apo) could be used for better imaging effects. However, Apo objectives did not have a long working distance and were only suitable for viewing glass slips, not for viewing thick samples such as petri dishes or culture bottles. 5. ** Numeric Aperture (NAC value)**: This is the main parameters of the objective lens and the condensing device. It is directly proportional to the resolution of the microscope, directly proportional to the magnifying power, and inverse proportional to the depth of field. UA = n * sin alpha. Under the same amplification, the higher the UA, the better. In the case where the working distance is satisfied, the objective lens with a high UA value should be selected. The numerical aperture of the dry objective lens was 0.05 - 0.95, and the numerical aperture of the oil-immersed objective lens was 1.25. 6. ** Working Distance (WD)**: - Ordinary working distance objective lens: The working distance is small, and the slices can be observed, but the petri dish cannot be observed. - [Long working distance objective lens: Used for inverted microscope. It can be used for microscopic examination of tissues, suspension, and other materials.] 7. ** Glass slide thickness **: After the optical type of the objective lens (infinity/0)(210/0), the number behind the slash represents the applicable glass slide thickness. For example,(infinity/0.17)(210/0.17), the applicable glass slide thickness is 0.17 mm. The objective lens with a higher NAC value was more sensitive to the thickness of the cover glass. Some objective lenses with high NAC values and those with long working distances had an adjustment ring for the thickness of the cover glass, which could be used for observation in petri dishes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to adjust the brightness of the exposure in the studio

You can adjust the brightness in the studio in the following ways: 1. ** exposure compensation **: If the camera has this function, you can manually adjust the exposure compensation to change the brightness in automatic mode. 2. ** Aperture, shutter, and sensitivity adjustment **: - ** Aperture **: The size of the aperture affects the amount of light that enters. The larger the aperture (the smaller the value), the more light enters, and the brighter the image. Otherwise, the image will be darker. When you need a small depth of field (blurring the background and emphasizing the main body), you can choose a large aperture, but you have to pay attention to ensuring sufficient brightness; if you want a large depth of field (overall clarity), you may need a small aperture, and at this time, you may need other methods to supplement the brightness. - ** Shutter Speed **: If the shutter speed is slow, the image will brighten if the light enters for a long time; if the shutter speed is fast, the image will darken if the light enters for a short time. However, if the shutter speed was too slow, the picture might be blurred due to hand shaking or subject movement. - ** Light sensitivity (USB)**: The higher the sensitivity, the more sensitive the image will be to light, and the brighter the image will be. However, high sensitivity may cause noise. 3. ** Lighting adjustment **: - ** Main light **: You can adjust the power of the main light (such as turning on the full light or reducing the power), as well as the distance and angle between the main light and the subject to control the brightness of the subject. For example, it would be brighter if it was close to the subject, and darker if it was far away. - ** Assistant light **: The auxiliary light can be used to supplement the light of the main light. The brightness of the screen can also be affected by adjusting its light intensity (such as turning on 1/2 light or less), as well as the distance and angle from the subject. - ** Contour Light (if available)**: Adjusts the effect on the silhouette and overall brightness of the character according to its power, distance, and angle. 4. ** Test Shot Observation and Illumination **: Take a test shot first, and then adjust the exposure parameters according to the shooting effect to achieve the ideal brightness. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to adjust the brightness in Canon photography mode

If you want to increase the brightness of the LCD screen, you can directly increase the brightness in the camera settings. If you want to increase the brightness (exposure) of the photo, you can increase the exposure compensation amount as needed (such as increasing 0.0.7, etc.). You can also use a tripod to shoot, so you don't have to worry about speed. However, when using a tripod to shoot, you have to turn off the camera's anti-shake function. In addition, the brightness could be adjusted by adjusting the sensitivity, shutter time, and aperture size. In the M-mode, you need to manually set the USB, shutter (detection speed), and aperture values, so that you can adjust the exposure of the camera in real time through the screen observation. In the automatic modes such as the TV and TV, the exposure control will be based on different modes. If the brightness of the photo was not enough in P, LV, and TV modes, the brightness of the photo could be adjusted by adjusting the exposure compensation. When shooting scenes with more white or black, the principle of white plus black minus should be followed to adjust the exposure compensation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
