1460DIB25 25 mm Dia. Standard Interference Bandpass Filter 1460nm
The 1460DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1460nm. 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 1453nm, and the cut-off wavelength is 1467nm, providing a narrow bandwidth for optimal performance. The center wavelength (CWL) of the filter is 1460nm, ensuring precise operation within the desired spectral region.
The filter is made from UVFS Mal- 1965, a material known for its excellent optical properties. It features a Thin Lens shape, which is beneficial for applications where space is a constraint. The filter has a diameter of 25mm and a thickness of 6.1mm, providing sufficient structural integrity while maintaining a compact form factor.
The front and back surfaces of the filter are coated with KNI 1460DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall signal-to-noise ratio.
