The 1660DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1660nm. 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 1653nm, and the cut-off wavelength is 1667nm, providing a narrow bandwidth for optimal performance.
The filter is made from UVFS MAL-1965, a material known for its excellent optical properties. It has a circular base shape, a common choice for its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unwanted optical effects.
The coating on both the front and back surfaces of the filter is KNI 1660DIB. This coating is specifically designed to enhance the filter's performance, ensuring high transmission within the passband and effective blocking outside it.
The filter's shape is classified as a Thin Lens, indicating that it may have lens-like properties, which can be beneficial in certain optical system configurations. This filter is currently in stock and available for immediate purchase through the vendor's website.
