FSQ-GG400 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 400nm

The FSQ-GG400 is a rectangular longpass filter, measuring 50.8 x 50.8 mm, sourced from the renowned optical vendor, MKS/Newport. This filter is designed with a specialized coating that allows for the absorption of light below a specific wavelength, in this case, 400nm, making it ideal for applications that require the removal of shorter wavelengths.

The filter boasts a thickness of 3mm, ensuring durability and stability in its placement within optical systems. Its base shape is rectangular, a common design for filters due to its ease of integration into various optical setups. The physical data of the filter indicates a cut-on wavelength of 400nm, meaning it begins to transmit light at this point, and a cut-off wavelength of 0nm, signifying that it blocks all wavelengths shorter than 400nm.

The coating on both the front and back of the filter is 'new gg400', a specialized coating developed by MKS/Newport for their filters. This coating ensures the filter's longevity and maintains its performance over time. The filter's shape is classified as a Thin Lens, indicating its potential use in lens systems.
