1400DIB25 25 mm Dia. Standard Interference Bandpass Filter 1400nm

The 1400DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1400nm. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical elements.

The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out unwanted wavelengths. This particular model has a cut-on wavelength of 1393nm and a cut-off wavelength of 1407nm, ensuring a narrow and precise bandwidth for your optical system.

The 1400DIB25 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 thickness of 6.1mm, providing sufficient structural integrity while minimizing unnecessary bulk.

The front and back surfaces of the filter are coated with KNI 1400DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflective losses and improving transmission efficiency.

The filter is currently in stock and available for immediate purchase. For more information, you can visit the product page at https://www.knightoptical.com/stock/default/1400nm-interference-bandpass-filter-25mmdiax14nmbw.html.
