680FIB12 12.5 mm Dia. Standard Interference Bandpass Filter 680nm

The 680FIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 680nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.

The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out other wavelengths. In this case, the passband ranges from 675nm to 685nm, making it ideal for applications that require narrow-band light in the red spectrum.

The 680FIB12 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 filter has a diameter of 12.5mm and a thickness of 6.1mm, providing a good balance between robustness and compactness.

The filter's coating is another notable feature. Both the front and back surfaces are coated with KNI 680DIB, a coating specifically designed to enhance the filter's performance. This coating helps to ensure high transmission within the passband and low reflection at the filter's surfaces.
