Using Lenses with Laser Diode Microscope to Reduce Aberrations

[bmihalik]

I would like to build a microscope witch can be used with different monochromatic light sources (laser diodes), and this system should has small astigmatic and coma aberration, but keep the chromatic aberration property. Can I use two spherical or ashperical lenses (facing with convex side to each other) from same material to decrease aberrations related to planar errors?

Yes, you can use two spherical or aspherical lenses from the same material to decrease aberrations related to planar errors. However, the type of aberration you are trying to reduce is dependent on the type of lens you choose. For example, spherical lenses will reduce astigmatism and coma aberration but will not reduce chromatic aberration. Aspherical lenses can reduce a variety of aberrations including chromatic aberration. Therefore, depending on what type of aberration you want to reduce, you may need to choose different types of lenses. Additionally, the quality of the lens material and its precision in manufacturing will also have an effect on the performance of the microscope.
