Superior blocking Can your filter block unwanted light from a laser or a bright LED?

We know that you wouldn't aim a laser
pointer directly on your imaging field of
view, like in this image.
But what if you use a laser or structured
illumination in your imaging process, and
you want to see it in one channel but not
in the other channel?
Or what if very bright light from a laser or
LED that you don’t want to detect is either
scattered or reflected into the scene?
ContrastMax filters provide the optical
density you need to block out that bright,
unwanted light and see only what
you want to see.
