220+ machine-vision filters — in stock, ready to ship.
Match the filter to the application — and the lighting.
Spec faster with data-driven selection tools.
Every vision system is tuned under perfect lab lighting — then it ships to a factory floor full of windows, forklift lamps, overhead glare, and stray laser light. A MidOpt filter controls the light so the system performs on-site, every shift. It’s roughly 1% of your bill of materials, protecting the other 99%.
FAT · PassPerfect, even light. The system reads every part. Factory Acceptance Test passes.
SAT · FailWindows, forklifts, and ceiling lights wash out contrast. The same system now misses parts.
SAT · PassA MidOpt bandpass passes your signal and blocks the rest. Repeatable on-site, in any conditions.
The whole method is one idea: choose a light source, then pass only that wavelength to the sensor. A red light and a red bandpass see the same color — and everything else goes dark.
Don’t know your wavelength? Start from your LED and we’ll match it.
Open the LED-to-Filter Guide →Isolate one color of light so the feature you care about pops and everything else falls away.
Kill ambient and off-band light that washes out contrast on the line.
See through surface coatings, inks, and obscurants the eye can’t.
Reveal scratches, residues, and defects invisible under white light.
Separate a weak emission signal from the strong light exciting it.
Cut specular hotspots off shiny, wet, or curved surfaces.
Tighten the band to a single wavelength and sharpen every edge.
Tame a bright scene without touching the lens or lighting.
Render true, repeatable color under any light source.
One camera, dawn-to-dark, switching IR-cut and IR-pass.
Map crop and vegetation health from reflected near-infrared.
Stop invisible IR from contaminating a color sensor.
Correct color temperature to match the source.
A sacrificial, cleanable front surface in harsh environments.
Start from your light source — we pair it to the matching bandpass.
