The 1600FIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1600nm. 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 1593.5nm and a cut-off wavelength of 1606.5nm, ensuring a tight control over the spectral range of transmitted light.
The 1600FIB25 is made from UVFS Mal-1965, a material known for its excellent optical properties. The filter has a thickness of 6.1mm, providing sufficient mechanical strength for most applications.
The front and back surfaces of the filter are coated with KNI 1600DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission in the desired wavelength range.
The filter's shape is that of a Thin Lens, which can be beneficial in certain optical systems where a lens-like element is required. The filter is currently in stock and available for immediate purchase through the vendor's website.
