According to the principles of microscopy, the image resolution will be nill if the diaphragm is closed not allowing any light through, so you will not be able to see anything.
Closing the iris diaphragm reduces the amount of light entering the lens, resulting in a darker image with decreased brightness. However, this reduction in light can potentially improve contrast by reducing any glare or overexposure in the image.
Opening the diaphragm under the stage of the microscope allows more light to pass through and brightens the image. Closing the diaphragm reduces the amount of light reaching the specimen, which can help reduce glare and improve contrast in the image. Adjusting the diaphragm is important for optimizing image quality and clarity.
Closing the condenser diaphragm too far can result in decreasing the amount of light entering the microscope, leading to a darker image. It may also reduce the resolution and contrast of the image by limiting the amount of light that interacts with the specimen. Adjusting the condenser diaphragm correctly helps optimize the quality of the image seen through the microscope.
Adjusting the diaphragm on a microscope controls the amount of light entering the lens, which helps to optimize the contrast and clarity of the image being viewed. Proper adjustment of the diaphragm can improve the visibility of details in the specimen being observed.
A telescope diaphragm is used to control the amount of light entering the telescope. By adjusting the size of the diaphragm, astronomers can regulate the brightness and contrast of the observed objects, improving visibility and clarity.
Closing the iris diaphragm reduces the amount of light entering the lens, resulting in a darker image with decreased brightness. However, this reduction in light can potentially improve contrast by reducing any glare or overexposure in the image.
Increasing the brightness or adjusting the contrast settings on the microscope can help increase image contrast in low power magnification. Additionally, using a higher quality objective lens or adjusting the illumination angle can also enhance image contrast.
Opening the diaphragm under the stage of the microscope allows more light to pass through and brightens the image. Closing the diaphragm reduces the amount of light reaching the specimen, which can help reduce glare and improve contrast in the image. Adjusting the diaphragm is important for optimizing image quality and clarity.
The optical characteristics of most lenses dictate that to obtain maximum optical quality, you ought to stop down at least 3 stops from maximum, as a general rule of thumb.
Closing the iris diaphragm reduces the depth of field, making it easier to distinguish between overlapping threads in the image. By decreasing the amount of light entering the microscope, you can increase contrast and resolution, improving visibility and making it easier to determine the thread order.
As you open the diaphragm under the stage, you allow more light to pass through the specimen. This can improve depth of focus but, it can also cause the image to become more washed out.
