20BPF70-400 50.8 x 50.8 mm Square Bandpass Filter 400nm
The 20BPF70-400 is a Bandpass Filter, specifically designed for rectangular geometries, offered by the renowned optical components vendor, MKS/Newport. This filter is characterized by its central wavelength of 400nm, making it ideal for applications that require precise filtering within this spectral range.
The filter boasts a base shape of 50.8 x 50.8 mm, providing a substantial surface area for efficient light interaction. It is constructed from UVFS MAL-1965, a material specifically chosen for its optical properties. The filter's thickness is 3.1241999999999996mm, offering a balance between robustness and light transmission.
The 20BPF70-400 features physical data that includes a cut-on wavelength of 365nm and a cut-off wavelength of 435nm. This ensures a tight bandpass around the central wavelength of 400nm, making it highly effective at filtering out unwanted wavelengths.
The filter's coating is another notable feature. Both the front and back surfaces are coated with New BPF10-400, a coating specifically designed to enhance the filter's performance within its specified wavelength range.
The filter's shape is classified as a Thin Lens, suggesting that it may have additional optical properties beyond simple wavelength filtering. However, these properties are not detailed in the provided data.
