Re: Need help with wavefront distortions on filter surfaces

Hi Mehmet,

Did you mount the right side of the dichroic towards the light source?
You might get double reflections from the surface and the coating, if
it is on the distant side.
Maybe you also reduce the angle of reflection, so that only absolute
reflection from the coating becomes likely.

This dichroic is not listed as suitable for lasers, so this could be
your broblem also....

yours, heini
