#E38E40 SP785 Modified Near-IR Dichroic Block Shortpass Filter

Designed to pass visible and shorter NIR wavelengths and assist in filtering near-IR light sources, SP785 can be considered in some cases as an alternative to using a DB735 filter. The second surface is provided with a high efficiency anti-reflection coating.

Useful Range : 425-770nm
Cut-off Wavelength 50% T : 785nm
Tolerance : +/- 10nm
Peak Transmission : ≥90%
Surface Quality : 40/20

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. Filters 62mm and greater have a surface quality tolerance of 60/40.
