Midwest Optical Systems LP610-67 Neutral Density Filter 25 Green Interference Bandpass M13Midwest Optical Systems LP610 67 Red Longpass M67 Longpass 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
