550DIB50 50 mm Dia. Standard Interference Bandpass Filter 550nm
The 550DIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light at a central wavelength of 550nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out unwanted light from other parts of the spectrum. This particular model has a cut-on wavelength of 545nm and a cut-off wavelength of 555nm, ensuring a tight bandpass and high spectral purity.
The 550DIB50 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 space is a constraint. The filter has a thickness of 6.1mm, providing sufficient mechanical strength while minimizing optical distortions.
The front and back surfaces of the filter are coated with KNI 550DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflections and improving transmission.
