66-099 50 mm Dia. SCHOTT RG665 Red Longpass Color Glass Filter 665nm
The 66-099 50 mm Dia. SCHOTT RG665 Red Longpass Color Glass Filter is a specialized optical component designed for applications requiring 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 various optical systems.
The filter's primary function is to allow light with wavelengths longer than 665nm to pass through while blocking or attenuating shorter wavelengths. This is achieved through the use of a specialized coating, denoted as "edm 54-659" on both the front and back surfaces. The cut-on wavelength is specified as 665nm, indicating the point at which the filter begins to transmit light. The cut-off wavelength is 0nm, suggesting that all wavelengths shorter than the cut-on are blocked.
The material ID for this filter is "uvfs mal- 1965", providing a unique identifier for the specific glass used in its construction. The filter's geometry is defined as a Thin Lens, suggesting a specific curvature and refractive index designed to minimize optical aberrations.
