LED to Filter Guide
MIDOPT FILTERS TO COMPLEMENT LED LIGHT SOURCES
BP Series Filters are recommended for use with all common LEDs used in machine vision lighting and designed with a broad passband to accommodate the entire output of the LED. BN Series Filters have a reduced bandwidth for overwhelming ambient light conditions or when greater separation of wavelengths is required.
MidOpt Filter Kits can be used to determine the optimal LED wavelength for your application
MidOpt Bandpass Filters are Designed for LED Illumination
MidOpt StablEDGE™ optical filters are specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12 mm) camera lenses.
The spectral output of an LED light source typically follows a normal Gaussian profile. For a machine vision bandpass filter to be most effective its passband should also approximate this bell-shaped curve.
