first of all thanks for helping. Aberration types are nothing but Aspherical and Chromatic. Any lens will definitely create some aberration but we don't want that right ? So I Found somewhere that using system of lens which have different focal length and different refractive index instead of a...

I want to make a collimator lens which can convert the diverging rays from and LCD at finite distance screen into parallel rays. But in order to reduce the aberrations, using system of lens is preferable than using a single lens. Can you suggest the way to create this kind of system please. I...

Yes you are absolutely right, But I have another doubt and that let's say star tracker captures two images from a LCD without collimator and with collimator, then will there be some aberrations present if yes then how to minimize them. Original image shown to LCD will get changed due the...
