The 46-590 is a UV Dielectric Hot Mirror, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in applications where a 0-degree angle of incidence (AOI) is required, and it is effective within the wavelength range of 245-1050nm.
The filter measures 50 x 50 mm, making it a square shape, and it has a thickness of 3mm. The material used for this filter is UVFS Mal-1965, a material known for its durability and optical clarity.
The 46-590 filter features a coating on both the front and back surfaces. This coating, identified as EDM 46-587, is a dielectric coating designed to enhance the filter's performance within its specified wavelength range.
The filter's physical data includes a cut-on wavelength of 245nm and a cut-off wavelength of 1050nm. This means that the filter will begin to transmit light at 245nm and will stop transmitting light at 1050nm.
The filter is available for purchase directly from the Edmund Optics website, and the link provided is valid and indicates that the filter is currently in stock.
