FSR-WG305 25.4 mm Dia. Colored Glass Absorptive Longpass Filter 305nm

The FSR-WG305 is a Longpass Filter, a type of optical element designed to transmit light with wavelengths longer than a specified value while blocking or absorbing shorter wavelengths. This particular filter has a diameter of 25.4 mm and a thickness of 3 mm, making it suitable for a wide range of optical applications.

The filter is manufactured by MKS/Newport, a leading vendor in the field of optical components, ensuring high quality and reliability. It is identified by the catalog number FSR-WG305, which can be used for easy reference and ordering. The filter's weblink status is "Valid - in stock", indicating its immediate availability for purchase and delivery.

The FSR-WG305 features a cut-on wavelength of 305 nm, meaning it starts to transmit light at this wavelength. The cut-off wavelength, which is the point at which the filter stops transmitting light, is 0 nm in this case, indicating that it transmits all wavelengths longer than 305 nm. This makes it a versatile tool for applications that require the selective transmission of longer wavelengths.

The filter's coating is listed as "new wg305" on both the front and back surfaces, providing consistent performance and protection. The filter's shape is described as a Thin Lens, suggesting that it may have some light-bending properties in addition to its filtering capabilities.
