The AT450lp is a Longpass Filter, designed and manufactured by Chroma, a leading vendor in the optical industry. This filter is specifically designed for rectangular geometries, with a width of 26 mm and a height of 38 mm, making it suitable for a wide range of applications.
The filter features a unique coating on both the front and back surfaces, identified as 'chr at450lp'. This coating is a result of a sophisticated sputter hard coating process, which enhances the filter's durability and performance. The coating is designed to allow light with wavelengths greater than or equal to 450 nm to pass through, while blocking shorter wavelengths. This property is known as the cut-on wavelength, which is 450 nm for the AT450lp.
The physical data of the filter indicates a cut-off wavelength of 0 nm, suggesting that it does not block any light below its cut-on wavelength. This feature makes it a versatile choice for various applications that require longpass filtering.
The AT450lp is currently in stock and available for purchase through the Chroma website. For more detailed information and specifications, users can refer to the product catalog number, AT450lp, and the provided weblink.
