20BPF10-660 50.8 x 50.8 mm Square Bandpass Filter 660nm
The 20BPF10-660 is a high-quality Bandpass Filter, offered by the renowned optical components manufacturer, MKS/Newport. This filter is specifically designed with a square geometry, measuring 50.8 x 50.8 mm, making it suitable for a wide range of optical applications.
The filter's primary function is to allow light transmission within a specific wavelength range while blocking light outside this range. The 20BPF10-660 is tuned to a central wavelength of 660nm, with a cut-on wavelength of 654.5nm and a cut-off wavelength of 665.5nm. This precise wavelength selection is crucial in various fields, including biomedical research, spectroscopy, and laser technology.
The filter is fabricated from UVFS Mal-1965, a material known for its excellent optical properties. It features a thickness of 3.0225999999999997mm, providing sufficient structural integrity while minimizing unwanted optical effects.
The 20BPF10-660 is coated with a New BPF10-660 coating on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The filter's shape is defined as a Thin Lens, suggesting that it may have some light-bending properties. However, this aspect should be confirmed with the manufacturer or through further technical specifications.
