Salient Features

LP347 Near-IR A/R Coated Glass Protective Window

Often referred to as a “sharp-cut” filter, Longpass Filters are specifically designed to pass a broad spectrum of longer wavelength light while blocking shorter wavelengths.

Economical solution for isolating specific spectral regions
Peak transmission ≥90%
Anti-reflection coated for maximum transmission in VIS and NIR spectrums
Can be used with Shortpass Filters for a custom, fine-tuned Bandpass Filter
Double-side polished glass for exceptional parallelism and optical flatness
Exceptional surface quality; 40/20 scratch/dig
Available in wavelength ranges from 350nm to 1500nm

LONGPASS FILTER APPLICATIONS:
Longpass Filters are often used in fluorescence applications to block an excitation light source or to pass multiple emission wavelengths, improving signal to noise ratio. Longpass Filters are also commonly used in photography and astronomy.

LP347 Near-IR Windows are anti-reflection-coated windows that are specifically optimized for near-infrared transmission, while still allowing visible light to pass. These windows are made of optically ground, polished and coated B270 crown glass, and are commonly used as protective cover glasses for cameras used in surveillance, LPR/ANPR and security applications that function primarily in the dark with help from infrared light sources.

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.
