850FIB25 25 mm Dia. Standard Interference Bandpass Filter 850nm

The 850FIB25 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 renowned vendor known for their high-quality optical elements.

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 850FIB25 is cut on at 845nm and cut off at 855nm, ensuring a narrow and precise bandwidth for your optical system.

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

The 850FIB25 features a KNI 850DIB coating on both the front and back surfaces. This coating enhances the filter's performance by ensuring high transmission within the passband and high rejection outside it. The filter's shape is classified as a Thin Lens, indicating its potential use in lens systems where minimal thickness is desirable.
