The 1280FIB12 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 components.
The filter is a 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 1274nm, and the cut-off wavelength is 1286nm, providing a narrow bandwidth for precise optical applications.
The filter is made from UVFS Mal- 1965, a material known for its optical properties in the infrared region. It has a thickness of 6.1mm, providing sufficient mechanical strength and durability. The coating on both the front and back surfaces is KNI 1280DIB, which enhances the filter's performance and longevity.
The 1280FIB12 filter features a Thin Lens shape, which can be beneficial in certain optical system designs. It is currently in stock and available for immediate purchase through the vendor's website.
