The 1300DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1300nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. The cut-on wavelength is 1294nm, and the cut-off wavelength is 1306nm, providing a narrow bandwidth for optimal performance. The center wavelength (CWL) of this filter is 1300nm, ensuring precise operation within the desired spectrum.
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 requiring minimal optical path deviation. The filter's geometry includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for various optical systems.
The coating on both the front and back surfaces of the filter is KNI 1300DIB. This coating enhances the filter's performance by ensuring high transmission within the passband and low transmission outside of it.
