1260DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1260nm
The 1260DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1260nm. 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 1254nm, and the cut-off wavelength is 1266nm, providing a narrow bandwidth for precise optical applications.
The filter is made from UVFS Mal-1965, a material known for its optical properties. It has a thickness of 6.1mm, providing sufficient structural integrity for most applications. The coating on both the front and back surfaces of the filter is KNI 1260DIB, which is specifically designed to enhance the filter's performance.
The filter's shape is that of a Thin Lens, which can be beneficial in certain optical systems where a lens effect is desired. The geometry of the filter, with its 12.5mm diameter, makes it compatible with many optical systems and setups.
