Reducing glare from incident light with Wild M7A

#1 Post by sreynolds » Thu Mar 23, 2023 1:34 pm

I'm working with sediment samples immersed in water, using a Wild M7A and halogen incident light via fiber optic source and getting glare from the light reflected by the water in my samples. Is there a simple polarizing filter (or other filter type) setup I can add to the Wild, maybe just under the objective lens, to cut the glare. Example picture below. Thanks.

Add water until everything is covered.

Ping-pong ball shade/diffuser.
Thanks Chas, it's not my original idea but mounted on the objective rather than the light source.
Gives a good flood of light.

You can put a polarizer on your lightbsource and a rotatable analyzer (ie a camera polarizer) on your main objective. It will gi e a different effect with tunable highlights. Diffusion is hard to beat though.
