FSQ-RG665 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 665nm
The FSQ-RG665 is a rectangular longpass filter, measuring 50.8 x 50.8 mm, designed for use in optical systems that require the absorption of shorter wavelengths. This filter is sourced from MKS/Newport, a reputable vendor in the optical industry.
The filter is constructed from UVFS Mal-1965 material, a type of colored glass that is well-suited for absorptive applications. It has a base shape of a thin lens, with a thickness of 3 mm, providing a robust and stable platform for optical systems.
The FSQ-RG665 features a longpass cut-on wavelength of 665nm, meaning it begins to transmit light at this wavelength and continues to do so for longer wavelengths. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths shorter than this. This makes it ideal for applications where the removal of shorter wavelengths is necessary.
The filter's coating is consistent on both the front and back surfaces, with a new RG665 coating. This coating enhances the filter's performance, ensuring reliable and consistent results in your optical system.
