1440DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1440nm
Knight Optical's 1440DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed for a central wavelength of 1440nm. This filter is a crucial component in various optical systems, particularly where precise wavelength selection and blocking of unwanted spectral ranges are required.
The filter is made from UVFS Mal-1965, a high-quality material known for its excellent optical properties. It features a Thin Lens shape, which is advantageous in applications where space is a constraint. The filter's geometry includes a diameter of 12.5 mm and a thickness of 6.1 mm, making it suitable for a wide range of optical setups.
The 1440DIB12 is coated with KNI 1440DIB on both the front and back surfaces. This coating enhances the filter's performance by ensuring high transmission at the desired wavelength and precise blocking of unwanted spectral ranges. The cut-on wavelength is 1433nm, and the cut-off wavelength is 1447nm, providing a narrow bandpass for optimal performance.
This filter is currently in stock and available for immediate shipping. For more information, you can visit the product page at https://www.knightoptical.com/stock/default/1440nm-interference-bandpass-filter-12-5mmdiax14nmbw.html.
