1120DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1120nm
The 1120DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1120nm. 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. This particular model has a cut-on wavelength of 1111.25nm and a cut-off wavelength of 1128.75nm, ensuring a narrow and precise band of transmitted light.
The 1120DIB12 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 front and back surfaces of the filter are coated with KNI 1120DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission efficiency.
The filter's shape is described as a Thin Lens, which suggests it may have some light-focusing properties. However, this should be confirmed with the vendor or in the product's technical specifications.
The 1120DIB12 is currently in stock and available for purchase on Knight Optical's website. For more information, users are encouraged to visit the provided weblink.
