1320DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1320nm
The 1320DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1320nm. 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 out other wavelengths. This particular model has a cut-on wavelength of 1313.75nm and a cut-off wavelength of 1326.25nm, making it ideal for applications that require narrow-band light transmission around the 1320nm range.
The 1320DIB12 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 that require minimal optical path deviation. The filter has a thickness of 6.1mm, providing sufficient mechanical strength while maintaining minimal impact on the optical path.
The front and back surfaces of the filter are coated with KNI 1320DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.
The filter is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
