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.

Why teams reach for a kit

One case turns "which filter?" from a guessing game into a bench test you finish the same afternoon.

Test before investing in hardware

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

Control the variability of ambient light

See how each filter cuts the stray ambient light that washes a feature out on the floor.

Evaluate glare reduction

Compare polarizers and coatings to kill specular glare off metal, glass, and film.

Solve applications quickly

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