850DIB25 25 mm Dia. Standard Interference Bandpass Filter 850nm

The 850DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 850nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The 850DIB25 is cut on at 845nm and cut off at 855nm, ensuring a narrow and precise bandpass. The central wavelength (CWL) of the filter is 850nm, indicating that this is the wavelength at which the filter has its maximum transmittance.

The filter is made from UVFS Mal-1965, a material known for its optical properties. It has a circular base shape, a common design for filters due to its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing optical distortions.

The 850DIB25 features a coating on both the front and back surfaces. This coating, known as KNI 850DIB, is specifically designed to enhance the filter's performance and durability. The filter's shape is classified as a Thin Lens, indicating that it has been designed to minimize optical aberrations and distortions.
