The 66-091 50 mm Dia. Hoya O-58 Red Longpass Color Glass Filter is a specialized optical component designed for applications that require longpass filtering at a specific wavelength. This filter, sourced from Edmund Optics, is a circular shape with a diameter of 50 mm and a thickness of 2.5 mm, making it suitable for various optical systems.
The filter's primary function is to allow light with wavelengths longer than 580 nm to pass through while blocking or attenuating shorter wavelengths. This is achieved through a precise coating process, resulting in a front coating of EDM 66-042 and a back coating of the same. The cut-on wavelength is 580 nm, indicating the point at which the filter begins to transmit light.
The material ID for this filter is UVFS MAL-1965, suggesting its composition and manufacturing process. The filter's geometry is that of a thin lens, which can be beneficial in certain optical configurations.
The filter's status is "Valid - in stock" as of the time of data collection, implying its availability for immediate use or purchase. The vendor for this item is Edmund Optics, a reputable supplier of optical components.
