940DIB25 25 mm Dia. Standard Interference Bandpass Filter 940nm
The 940DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 940nm. 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 unwanted light from other parts of the spectrum. In this case, the 940DIB25 is designed to pass light between 935nm and 945nm, making it ideal for applications that require narrow-band light in the near-infrared region.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties in the infrared spectrum. It has a circular base shape, with a thickness of 6.1mm, providing robustness and stability. The filter's coating, KNI 940DIB, is applied on both the front and back surfaces, further enhancing its performance and durability.
The 940DIB25 is shaped as a Thin Lens, which can be beneficial in certain optical systems where a lens-like element is required. The filter is currently in stock and available for immediate purchase through the vendor's website.
