Bandpass filters transmit a specific portion of the spectrum while blocking shorter and longer wavelengths. The resulting increase in signal-to-noise ratio improves contrast and insures control of changes that may occur in ambient lighting conditions. Broad bandwidth, angular insensitivity and rugged designs allow our bandpass filters to be used with very wide angle lenses regardless of the varying spectral output of LED and laser diode lighting.
Enhanced contrast for viewing of desired features
Designed for compatibility with all commonly used LED and laser diode wavelengths and UV excited fluorescence emissions
Shields systems from unwanted ambient light
Limits the loss of resolution associated with chromatic aberrations
Aids in increased LED light stability and longevity by facilitating operation at reduced power levels
Essential for successful imaging in the UV and Near-IR. Visible light must be blocked to maximize contrast in these situations.
