810DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 810nm
The 810DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 810nm. 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. In this case, the cut-on wavelength is 805nm, and the cut-off wavelength is 815nm, making it highly effective in isolating the 810nm wavelength.
The 810DIB12 is made from UVFS MAL-1965, a material known for its optical properties and durability. It has a thickness of 6.1mm, providing sufficient structural integrity for most applications.
The coating on both the front and back surfaces of the filter is KNI 810DIB. This coating is specifically designed to enhance the filter's performance, ensuring optimal transmission and blocking of the specified wavelengths.
The filter's shape is that of a Thin Lens, which is beneficial in applications where minimal optical distortion is required. This shape, combined with its high-quality coating and material, makes the 810DIB12 an excellent choice for various optical systems.
According to the vendor, the filter is currently in stock and can be purchased directly from their website through the provided weblink. The link's status is valid, ensuring a smooth and reliable purchasing process.
