1280DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1280nm
The 1280DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1280nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 1274nm, and the cut-off wavelength is 1286nm, providing a relatively narrow bandwidth for precise optical applications.
The filter is made from UVFS Mal-1965, a material with excellent optical properties. It has a thickness of 6.1mm, which is suitable for most optical systems. The coating on both the front and back surfaces is KNI 1280DIB, which is specifically designed for this filter to enhance its performance.
The shape of the filter is Thin Lens, which is beneficial in applications where the filter needs to focus or collimate light. The filter is currently in stock and available for immediate shipping, as indicated by its weblink status.
