656DIB50 50 mm Dia. Standard Interference Bandpass Filter 656.3nm
The 656DIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to isolate the 656.3nm wavelength. Manufactured by Knight Optical, a trusted vendor in the optical industry, this filter is an essential component for various applications.
This filter is a Bandpass Filter, a type of optical filter that only allows a specific range of wavelengths to pass through while blocking others. The 656DIB50 is designed with a Cut-on wavelength of 651.3nm and a Cut-off wavelength of 661.3nm, ensuring a tight passband around the desired 656.3nm wavelength.
The filter is made from UVFS Mal-1965, a high-quality material known for its excellent optical properties. It features a Thin Lens shape, which is beneficial for applications where space is a constraint. The filter's geometry includes a diameter of 50mm and a thickness of 6.1mm, providing a robust and compact design.
The front and back of the filter are coated with KNI 656DIB, a specialized coating that enhances the filter's performance and durability. This coating ensures high transmission at the desired wavelength and excellent blocking of unwanted wavelengths.
