FSQ-RG695 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 695nm
The FSQ-RG695 is a Longpass Filter from MKS/Newport, designed with a rectangular base shape and a size of 50.8 x 50.8 mm. This filter is part of the UVFS MAL-1965 material ID family and is characterized by its absorptive coating, which is applied to both the front and back surfaces.
The primary function of this filter is to allow light transmission above a specified wavelength while blocking or absorbing light below that wavelength. In the case of the FSQ-RG695, the cut-on wavelength is 695nm, indicating that it begins to transmit light at this point in the spectrum. The cut-off wavelength, on the other hand, is 0nm, meaning it blocks all wavelengths below 695nm.
The filter has a thickness of 3mm, which contributes to its overall durability and stability. Its shape is classified as a Thin Lens, suggesting that it may have some lens-like properties, although this is not explicitly stated in the provided data.
The FSQ-RG695 is currently in stock and can be purchased directly from the vendor's website. For more detailed information, including pricing and availability, please refer to the provided weblink.
