FSQ-RG9 50.8 x 50.8 mm Colored Glass Absorptive Longpass Filter 725nm
The FSQ-RG9 is a rectangular longpass filter, measuring 50.8 x 50.8 mm, sourced from the renowned optical component vendor, MKS/Newport. This filter is designed with a specialized coating that allows for the absorption of specific wavelengths of light, making it an ideal component for various optical applications.
The filter's primary function is to cut on at 725nm, meaning it begins to absorb light at this wavelength, while it has no specified cut off wavelength, indicating it continues to absorb all longer wavelengths. This characteristic makes it particularly useful in applications where the elimination of specific wavelengths is required.
The FSQ-RG9 boasts a base shape of a thin lens, with a thickness of 3mm, providing durability and stability in its setup. The filter's geometry is designed to fit into various optical systems, making it a versatile component for a wide range of applications.
The filter's coating, both on the front and back, is identified as 'new rg9'. This coating is crucial in determining the filter's performance, particularly in its ability to absorb specific wavelengths. The 'new rg9' coating ensures high-performance and reliability, making the FSQ-RG9 a trusted component in optical systems.
