1220DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1220nm
The 1220DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1220nm. 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 cut-on wavelength is 1214.5nm, and the cut-off wavelength is 1225.5nm, providing a narrow bandwidth for precise optical applications.
The 1220DIB12 filter is made from UVFS Mal- 1965, a material known for its optical properties. It 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 1220DIB, which is specifically designed to enhance the filter's performance.
The filter's geometry is that of a Thin Lens, making it suitable for use in optical systems where minimal optical path deviation is required. The 1220DIB12 is currently in stock and available for immediate purchase through the vendor's website.
