The 636FIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light at a central wavelength of 636nm. 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 light within a specific range of wavelengths to pass through while blocking out other wavelengths. In this case, the passband ranges from 631nm to 641nm, making it ideal for applications that require narrow-band light in the red spectrum.
The 636FIB12 is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a Thin Lens shape, which is beneficial for applications that require minimal optical path deviation. The filter's geometry includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for use in compact optical systems.
The filter's front and back surfaces are coated with KNI 636DIB, a coating that enhances its performance within the specified passband. This coating ensures high transmission and low reflection, contributing to the filter's overall efficiency.
