Midwest Optical Systems LP171-82 Fixed Focal Length allowing these high performance lensesMidwest Optical Systems LP171 82 Fused Silica Multi Layer Vis A R Coated Protective Window M82 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
