This is a question related to the on-going two-color simultaneous imaging updates:

could you enlighten me how you deal with the different chromatic aberration at different wavelengths?


Optics / relay grin lens VS cylindrical glass
« on: January 20, 2017, 05:07:15 PM »
This optic-principle related question is making me thinking now, and I hope you could help me out.

The relay grin lens should be 0.5 or 1 pitch and to bring all the light from bottom to the top of it. I wonder why not just leave the space empty or use some cylindrical glass (with homogeneous index) for that function. I imagine it would be like to see from air or through a piece of glass from the top.

Hope it is not too naive. Thanks!
