The 54-661 12.5 mm Dia. SCHOTT RG715 Black Longpass Color Glass Filter is a specialized optical component designed for applications requiring longpass filtering at a wavelength of 715nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their online catalog.
The filter is a circular component with a diameter of 12.5mm and a thickness of 3mm, making it suitable for use in a wide range of optical systems. It is constructed from SCHOTT UVFS MAL-1965, a high-quality glass material known for its excellent optical properties.
The RG715 designation indicates that this filter has a cut-on wavelength of 715nm. This means that it begins to transmit light at this wavelength, while blocking or attenuating light at shorter wavelengths. The cut-off wavelength is 0nm, indicating that this filter does not block any light at wavelengths longer than 715nm.
The filter features coatings on both the front and back surfaces, identified as EDM 54-661. These coatings are likely designed to enhance the filter's performance, such as by increasing its transmission efficiency or improving its durability.
The filter's shape is described as a Thin Lens, suggesting that it may have some degree of optical power. However, the specific details of this power are not provided in the item data.
