Midwest Optical Systems LP285-58 SWIR Longpass Filter these lenses withstand exposure toMidwest Optical Systems LP285 58 High Transmission Heat Resistant A R Protective Window M58 Protective Filters 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. 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.
