FGL610M Dia. 25 mm SM1-Mounted Colored Glass Filter; 610nm Longpass

The FGL610M is a color glass filter developed by Thorlabs, a leading vendor in the optical industry. This filter, with a catalog number FGL610M, is specifically designed for use in optical systems that require longpass filtration at 610nm. The filter is mounted in an SM1-compatible thread, ensuring ease of integration into various optical setups.

The FGL610M filter boasts a circular geometry with a diameter of 25 mm and a thickness of 2 mm. The base shape of the filter is made of n-bk7 Schott material, a common choice in the industry due to its excellent optical properties. The filter's physical data includes a cut-on wavelength of 610nm, meaning it begins to transmit light at this point, and a cut-off wavelength of 0nm, indicating it transmits all wavelengths below this point.

The filter's coating is a crucial component, enhancing its performance. Both the front and back surfaces of the FGL610M are coated with a specialized coating, denoted as 'tho fgl610'. This coating is designed to optimize the filter's performance, ensuring efficient longpass filtration at the specified wavelength.

The FGL610M filter is available in a thin lens shape, further enhancing its versatility in various optical applications. The filter's current status is 'in stock', as indicated by its weblink, which is valid and leads to the product page on Thorlabs' official website.
