54-662 12.5 mm Dia. SCHOTT RG780 Black Longpass Color Glass Filter 780nm
The 54-662 12.5 mm Dia. SCHOTT RG780 Black Longpass Color Glass Filter is a high-quality optical component designed for use in a wide range of applications. Sourced from the renowned optical vendor Edmund Optics, this filter boasts a 12.5 mm diameter and a thickness of 3 mm, making it a versatile and robust choice for various optical systems.
This filter is specifically designed to transmit light with wavelengths of 780 nm and above, while effectively blocking light with shorter wavelengths. This longpass characteristic is crucial in many applications where specific wavelengths need to be isolated or emphasized. The filter's "Black" designation indicates that it has been treated to minimize reflection and scatter, further enhancing its performance.
The filter's geometry is defined by its circular shape and thin lens design, which helps to minimize optical aberrations and distortions. The material ID, UVFS MAL-1965, provides a unique identifier for the specific glass used in the filter's construction.
The coating on both the front and back surfaces of the filter is identified as EDM 54-662. This coating is designed to enhance the filter's performance by reducing surface reflections and improving transmission efficiency.
