66-079 50 mm Dia. SCHOTT GG420 Yellow Longpass Color Glass Filter 420nm

The 66-079 50 mm Dia. SCHOTT GG420 Yellow 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 50 mm diameter and a thickness of 3 mm, making it suitable for a wide range of optical systems.

The filter's primary function is to allow light with wavelengths longer than 420nm to pass through while blocking or attenuating shorter wavelengths. This is achieved through the use of a specialized coating, denoted as "edm 46-425" on both the front and back surfaces. The cut-on wavelength is 420nm, indicating the point at which the filter begins to transmit light. The cut-off wavelength is 0nm, suggesting that the filter blocks all wavelengths shorter than 420nm.

The material ID for this filter is UVFS MAL-1965, providing a unique identifier for the specific type of glass used in its construction. The filter's geometry is described as a Thin Lens, suggesting that it has been designed to minimize optical aberrations and distortions.

The filter's current status is "in stock", and it is available for purchase through the Edmund Optics website, as indicated by the valid weblink status. This filter is a valuable addition to any optical system that requires longpass filtering at the 420nm wavelength.
