Dark Red Bandpass Filter

MidOpt® BP660 Dark Red Bandpass Filters are recommended for use with 650-680nm LED and laser diode lighting. Because of the ample passband and excellent in-band transmission, it works well with all camera-related applications in this range.

It is best to double check the wavelength of red lighting used in your application before ordering.

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.

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.
StablEDGE™ filters take advantage of absorptive filter glass to form the leading
edge of the filter passband.This assures no shifting in this region, even when the
lens FOV exceeds 100°.StablEDGE™ designs are  less angle-of-incidence sensitive, inherently more rugged, and are environmentally stable.
