1280DIB25 25 mm Dia. Standard Interference Bandpass Filter 1280nm

The 1280DIB25 is a 25 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 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 1274nm, and the cut-off wavelength is 1286nm, providing a narrow bandwidth for optimal performance. The center wavelength (CWL) of the filter is 1280nm, ensuring precise operation within the intended spectral range.

The filter is made from UVFS Mal- 1965, a material known for its excellent optical properties. It has a circular base shape, a common design for filters due to its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity for handling and installation.

The coating on both the front and back surfaces of the filter is KNI 1280DIB. This coating is specifically designed to enhance the filter's performance, ensuring high transmission within the passband and effective blocking outside of it.

The filter's shape is described as a Thin Lens, indicating that it may have lens-like properties, potentially useful in certain optical system configurations.
