670DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 670nm

The 670DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 670nm. This filter is sourced from Knight Optical, a reputable 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 665nm, and the cut-off wavelength is 675nm, making it highly effective in isolating the 670nm wavelength.

The 670DIB12 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 filter's coating, KNI 670DIB, is applied on both the front and back surfaces, further enhancing its performance and protection.

The geometry of the filter is that of a Thin Lens, which can be beneficial in certain optical systems where minimal optical path difference is desired. The filter's diameter is 12.5mm, making it suitable for a wide range of applications.
