45-061 50.8 x 50.8 mm SCHOTT N-WG305 Longpass Color Glass Filter 309nm

The 45-061 is a 50.8 x 50.8 mm SCHOTT N-WG305 Longpass Color Glass Filter, designed to transmit light with wavelengths longer than 309nm. This filter is sourced from Edmund Optics, a leading provider of optical components.

The filter is a part of the Color Glass category, which is known for its ability to selectively transmit or block specific wavelengths of light, based on the filter's material properties. This particular filter is rectangular in shape, making it suitable for a wide range of optical applications.

The filter's geometry includes a width and height of 50.8mm each, with a thickness of 3mm. This ensures the filter's durability and stability within an optical system. The filter's physical data includes a cut-on wavelength of 309nm, indicating the point at which the filter begins to transmit light. The cut-off wavelength is 0nm, meaning the filter will transmit all wavelengths longer than its cut-on wavelength.

The filter features a coating on both the front and back surfaces, identified as EDM 54-646. This coating is likely designed to enhance the filter's performance, such as by reducing surface reflections or increasing transmission efficiency. The filter's shape is described as a Thin Lens, suggesting it may have lens-like properties, such as focusing or collimating light.

The filter is currently in stock and available for purchase through the provided weblink. With its robust specifications and reliable performance, the 45-061 is an excellent choice for applications requiring longpass filtration.
