The 66-071 50 mm Dia. SCHOTT N-WG280 Longpass Color Glass Filter is a high-quality optical component designed for applications that require longpass filtering at a wavelength of 285nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.
The filter is a circular component with a diameter of 50mm and a thickness of 3mm, making it suitable for a wide range of optical systems. It is made from UVFS Mal-1965, a material specifically chosen for its optical properties in the ultraviolet spectrum.
The N-WG280 Longpass Color Glass Filter features a cut-on wavelength of 285nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths above 285nm. This makes it ideal for applications that require the removal of shorter wavelengths, such as in fluorescence microscopy or UV spectroscopy.
Both the front and back surfaces of the filter are coated with EDM 64-509, a coating that enhances its performance and durability. The filter's shape is described as a Thin Lens, suggesting that it may have lens-like properties, although this is not explicitly stated in the provided data.
