476 US LPF-12.5 12.5 mm Dia. Mounted Ultra-Steep Longpass Filter
The 476 US LPF-12.5 is a Longpass Filter, part of the extensive catalog of optical elements offered by Iridian Spectral Technologies. This filter, with a catalog number of 476 US LPF, is available for purchase directly from the vendor's website, as indicated by the "weblink status" field.
The filter is circular in shape, with a diameter of 12.5 mm and a thickness of 3 mm, making it suitable for a wide range of optical applications. The base shape is a Thin Lens, and the material used in its construction is UVFS Mal-1965.
The 476 US LPF-12.5 features a cut-on wavelength of 476.4 nm, indicating that it begins to transmit light at this wavelength. The cut-off wavelength, on the other hand, is 0 nm, meaning it transmits all wavelengths longer than its cut-on wavelength. This makes it an ideal choice for applications that require the transmission of longer wavelengths while blocking shorter ones.
The filter's coating is identical on both the front and back surfaces, with the designation "irr 476-us-lpf". This coating contributes to the filter's performance, ensuring accurate and consistent transmission of light.
