The FSR-RG1000 is a Longpass Filter by MKS/Newport, designed with a circular shape and a diameter of 25.4 mm. This filter is part of the UVFS MAL-1965 material ID family and has a thickness of 3 mm.
The filter's primary function is to allow light transmission at wavelengths above 1000 nm while blocking or absorbing shorter wavelengths. This is reflected in its physical data, where the cut-on wavelength is 1000 nm and the cut-off wavelength is 0 nm.
The FSR-RG1000 features the same coating on both the front and back surfaces, specifically the 'new rg1000' coating. This coating enhances the filter's performance and durability.
The filter's shape is described as a Thin Lens, suggesting it may have lens-like properties. This could be beneficial in certain optical applications where lens-like behavior is desired.
According to the vendor's website, the FSR-RG1000 is currently in stock and available for purchase. The catalog number for this item is FSR-RG1000, and more information can be found on the Newport website.
