860DIB25 25 mm Dia. Standard Interference Bandpass Filter 860nm
The 860DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 860nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 855nm, and the cut-off wavelength is 865nm, providing a narrow bandwidth for optimal performance.
The 860DIB25 is made from UVFS Mal-1965, a material known for its excellent optical properties. It features a Thin Lens shape, which is beneficial for applications where minimal thickness is required. The filter has a diameter of 25mm and a thickness of 6.1mm, making it suitable for various optical systems.
The coating on both the front and back surfaces of the filter is KNI 860DIB. This coating enhances the filter's performance by ensuring high transmission within the passband and low transmission outside of it.
