900DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 900nm
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.
According to the vendor, the filter is currently in stock and can be purchased directly from Knight Optical's website. The link to the product page is provided for convenience.
