850FIR25 25 mm Dia. Broadband Interference Bandpass Filter 850nm

The 850FIR25 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 applications that require precise wavelength selection within the 850nm range.

The filter is circular in shape, with a diameter of 25mm and a thickness of 6.1mm, making it compatible with a wide range of optical systems. The base material of the filter is UVFS Mal-1965, a durable and reliable material known for its optical properties.

The 850FIR25 features a broadband interference design, with a cut-on wavelength of 830nm and a cut-off wavelength of 870nm. This ensures a high level of transmission within the desired wavelength range, while effectively blocking out unwanted wavelengths. The central wavelength (CWL) of the filter is 850nm, providing a precise and accurate wavelength selection.

The filter is coated with KNI 850DIR on both the front and back surfaces. This coating enhances the filter's performance and durability, providing excellent resistance to environmental factors and ensuring a long service life.

The 850FIR25 is available in a thin lens shape, which is ideal for applications where space is limited or a thin optical element is required. The filter is currently in stock and available for immediate delivery, as indicated by its valid weblink status.
