The 1300DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1300nm. 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 out light from other wavelengths. This particular model has a cut-on wavelength of 1294nm and a cut-off wavelength of 1306nm, making it ideal for applications that require narrow-band light transmission around the 1300nm region.
The 1300DIB25 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 space is a constraint. The filter has a thickness of 6.1mm, providing sufficient structural integrity while minimizing unnecessary bulk.
The front and back surfaces of the filter are coated with KNI 1300DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission efficiency.
