FB1 FB3 Protective Optical Glass Filter

FB1 FB3 Protective Optical Glass Filter 

FB1 and FB3 Colored Glass Filters are selective absorption optical filters, widely used in spectrometers, photography, and scientific experiments. FB1 is lighter in color, while FB3 is darker, both in dark olive green. They feature high transmittance and high blocking, effectively filtering specific light wavelengths. Compared to dielectric filters, colored glass filters offer a more cost-effective solution and can easily cover a wide wavelength range. Our products, made from high-quality optical glass and precision-engineered, ensure excellent optical performance and durability.
