The 900DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 900nm. 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 895nm, and the cut-off wavelength is 905nm, making it highly efficient at filtering out unwanted wavelengths around the central 900nm wavelength.
The 900DIB12 filter is made from UVFS Mal- 1965, a material known for its optical properties and durability. The filter has a thickness of 6.1mm, providing sufficient structural integrity for most applications.
The coating on both the front and back surfaces of the filter is KNI 900DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance and durability, ensuring reliable operation over time.
The filter's shape is a Thin Lens, which is a common shape for optical components. This shape allows for easy integration into optical systems, making the 900DIB12 a versatile choice for various applications.
