› BANDPASS FILTERS

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 MidOpt Bandpass filters to be used with very wide angle lenses regardless of the varying spectral output of LED and laser diode lighting.

The performance of a filter is based on what happens to light passing through the filter. The apparent color of light reflected off the surface is not a reliable way to judge the filter's capabilities. Batch-to-batch difference in the apparent color of the coatings or filter substrates can often be easily seen when looking at two examples of the same filter type. The color of the coating does not indicate a disparity in performance.
