770DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 770nm

The 770DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 770nm. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical components.

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 765nm, and the cut-off wavelength is 775nm, making it highly effective in isolating the desired wavelength.

The 770DIB12 filter is made from UVFS Mal- 1965, a material specifically chosen for its optical properties. It has a thickness of 6.1mm, which is optimal for its intended application. The filter's coating, KNI 770DIB, is applied on both the front and back surfaces, further enhancing its performance.

The filter's shape is that of a Thin Lens, which is beneficial in certain optical systems due to its minimal thickness. This filter is currently in stock and available for immediate use. For more information, you can visit the vendor's website through the provided weblink.
