Laser line interference filters have extremely narrow band (+/-3nm and 10nm), broadband (+/-50nm and +/-80nm), and linear variable transmittance across the substrate. They are extremely angle sensitive, so care should be taken when mounting and placing them within an optical train. Although high selective, they do reduce throughput of the peak wavelengths significantly (make sure to compensate with increased illumination).
