Built on StablEDGE®

The bandpass filters in this kit hold their passband across the real range of ray angles in a lens — so the contrast you dial in on the bench survives on the floor.

Swap filters on your own part, under your own lighting, before you commit to a production order.

Reduce light intensity in the visible spectrum without affecting color and contrast

Test in both monochrome or color applications

Swap filters on your own part, under your own lighting, before you commit to a production order.

Solve applications quickly

Narrow the right filter down in an afternoon on the bench — not a quarter of sampling.
