1180DIB25 25 mm Dia. Standard Interference Bandpass Filter 1180nm
The 1180DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1180nm. 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 light outside this range. The cut-on wavelength is 1174.5nm, and the cut-off wavelength is 1185.5nm, providing a narrow bandwidth for precise optical applications.
The 1180DIB25 is made from UVFS Mal-1965, a material known for its optical properties and durability. It features a Thin Lens shape, which is beneficial for applications requiring minimal optical path deviation. The filter has a thickness of 6.1mm, providing structural rigidity while maintaining a low profile.
The front and back surfaces of the filter are coated with KNI 1180DIB, 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, please refer to the vendor's website using the provided weblink.
