FSQ-WG295 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 299nm
The FSQ-WG295 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, new wg295, on both the front and back surfaces, ensuring optimal performance.
The FSQ-WG295 is a longpass filter, characterized by its cut-on wavelength of 299nm. This specific filter allows all wavelengths greater than 299nm to pass through, while effectively blocking shorter wavelengths. The cut-off wavelength is 0nm, indicating that there is no upper limit to the wavelengths that can pass through.
The filter is 3mm thick, making it robust and durable. It features a thin lens shape, which is beneficial for certain optical applications. The physical dimensions of the filter, including its width and height, are precisely 50.8mm, making it compatible with a wide range of optical systems.
The FSQ-WG295 is made from UVFS Mal-1965, a specialized optical material known for its excellent transmission properties in the ultraviolet and visible spectra. This material is particularly suitable for applications that require high-performance longpass filters.
The filter is currently in stock and available for purchase through the MKS/Newport website. For more information, please refer to the provided weblink.
