MidOpt - LP780 Near-Infrared (IR) Longpass Filter

The MidOpt LP780 Near-Infrared (IR) Longpass Filter is recommend for use with laser diodes and LED lighting that operates within the 810-830nm range. Longpass filters are often referred to as "sharp-cut" filters and are specifically designed to pass a broad spectrum of longer wavelength light while blocking shorter wavelengths. They're commonly used in fluorescence applications to block an excitation light source or to pass multiple emission wavelengths, improving signal-to-noise ratio. The MidOpt BP810 is the ideal alternate-use bandpass filter. MidOpt Longpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths, are double-side polished for exceptional parallelism and optical flatness and are anti-reflection (AR) coated to limit glare and minimize reflection loss.
