    finite conjugates cassegrain design

    Yes, I'm constrained to reflective optics. What's the best design for this kinda system? I outline that the obj-to-secondary mirror distance must be between 13 to 18 cm and that the obj height is no more than 0.125 mm. The image must be collected on an N.A.=0.22 optical fiber. What do u suggest...

    finite conjugates cassegrain design

    I have to design a Cassegrain optical device for finite conjugates (obj height <0.125mm). The object minimum-maximum distances required from the primary mirror are: 13-16 cm. Does anybody know the best radium-to-radium ratio and primary mirror radium-to-mirror spacing for best performance in...
