630DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 630nm
The 630DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 630nm. This filter is sourced from Knight Optical, a renowned 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 625nm, and the cut-off wavelength is 635nm, making it ideal for applications that require narrow-band light in the red spectrum.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a thickness of 6.1mm, which is suitable for most optical systems. The coating on both the front and back surfaces is KNI 630DIB, a proprietary coating developed by Knight Optical for enhanced performance.
The filter's geometry is that of a Thin Lens, which can be beneficial in certain optical configurations. The diameter of 12.5mm is a standard size, making it compatible with many optical systems and components.
