FSQ-WG305 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 309nm
The FSQ-WG305 is a high-quality absorptive longpass filter, designed and manufactured by MKS/Newport. This filter is specifically engineered for use in optical systems that require precise wavelength control and blocking. The FSQ-WG305 is a rectangular filter, with a base shape that ensures easy integration into various optical setups.
The filter has a width and height of 50.8 mm each, making it suitable for applications that require a larger filter size. It has a thickness of 3 mm, providing robustness and stability during operation. The filter is coated on both the front and back with the New WG305 coating, enhancing its performance and longevity.
The FSQ-WG305 is designed to cut on at 309 nm, effectively blocking wavelengths below this point. It does not have a specified cut-off wavelength, indicating that it allows all wavelengths above 309 nm to pass through. This makes it ideal for applications that require the blocking of specific wavelengths while allowing others to pass.
The filter is made from UVFS Mal-1965, a specialized optical material known for its excellent optical properties. It is shaped as a thin lens, further enhancing its functionality and integration into optical systems. The catalog number for this filter is FSQ-WG305, and it is available for purchase directly from MKS/Newport.
