930DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 930nm
The 930DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 930nm. This filter is sourced from Knight Optical, a renowned 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 light outside this range. The 930DIB12 is cut on at 925nm and cut off at 935nm, providing a narrow bandwidth for precise optical applications. The center wavelength (CWL) of the filter is 930nm, ensuring optimal performance in systems designed to operate at this wavelength.
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 minimal thickness is required. The geometry of the filter includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for use in various optical systems.
The front and back of the filter are coated with KNI 930DIB, a coating specifically designed to enhance the performance of the filter. This coating ensures high transmission rates within the passband and low absorption, providing superior optical performance.
