Midwest Optical Systems LP418-58 UV Block 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. Longpass Filters are also commonly used in photography and astronomy.
These filters feature Double-side polished glass for exceptional parallelism and optical flatness.
