The 54-653 12.5 mm Dia. SCHOTT OG515 Yellow Longpass Color Glass Filter is a specialized optical component designed for applications that require longpass filtering at a wavelength of 515nm. 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 a wide range of optical systems. It is constructed from SCHOTT optical glass, a high-quality material known for its excellent optical properties and durability. The filter features a yellow longpass coating, denoted as 'edm 54-653' on both the front and back surfaces, which provides a cut-on wavelength of 515nm. This means that the filter begins to transmit light at this wavelength, while blocking or attenuating shorter wavelengths.
The physical data of the filter indicates a cut-off wavelength of 0nm, suggesting that it allows the transmission of all wavelengths longer than 515nm. This makes it ideal for applications that require the removal of shorter wavelengths, such as fluorescence microscopy or astronomical imaging.
The filter is shaped as a thin lens, which can be beneficial in certain optical configurations. It is currently in stock, according to the vendor's website, and further information can be found through the provided weblink.
