940FIR12 12.5 mm Dia. Broadband Interference Bandpass Filter 940nm

The 940FIR12 is a high-quality bandpass filter, designed and manufactured by Knight Optical, a leading vendor in the optical industry. This filter is specifically engineered for use in broadband applications, with a center wavelength of 940nm, making it ideal for a wide range of optical systems and setups.

The filter is circular in shape, with a diameter of 12.5mm, providing a substantial surface area for efficient light transmission. It has a thickness of 6.1mm, ensuring robustness and durability. The 940FIR12 is cut on at 917.5nm and cut off at 962.5nm, providing a narrow, precise bandwidth for optimal performance.

The 940FIR12 features a KNI 940DIR coating on both the front and back surfaces. This coating enhances the filter's performance by reducing reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system.

The filter is designed in a thin lens shape, which not only adds to its robustness but also allows for easy integration into various optical systems.
