Optical Lens Selection

  1. Nov 24, 2005 #1

    I'm trying to set up a lens system as follows:

    - Laser source 612nm
    - This passes through an apature to act as a spatial filter...
    - then through non-reflective glass onto a crystal of diameter upto 150um
    - the lens must then take the diffraction pattern from this crystal upto 50 degrees from the optical axis and focus onto a 7x9mm CCD

    I have looked though a couple of catalouges and spoken to some people, but I keep having different terminology and jargon thown at me, and since my optics understanding is limited, I was hoping someone might guide me into how to make the right choice of lens. How do I minimise the abberations/distortions/other possible elements of error!

    Ok, now I've been presented with the idea of using a reflecting ellipsoid... can anyone give me some pointers on how to set it up?
