FGL495M Dia. 25 mm SM1-Mounted Colored Glass Filter; 495nm Longpass

The FGL495M is a color glass filter, offered by Thorlabs, with a catalog number FGL495M. This filter is designed with a longpass wavelength of 495nm and is mounted on an SM1 (1.035"-40) thread, providing compatibility with various optical systems. The filter's geometry includes a diameter of 25 mm and a thickness of 2 mm, ensuring a compact and robust design.

The FGL495M filter is made of N-BK7 Schott material, a well-known and widely used optical glass. This material is known for its excellent optical properties and durability. The filter's coating, both on the front and back, is 'tho fgl495', which is a proprietary coating developed by Thorlabs to enhance the filter's performance and durability.

The physical data of the FGL495M filter indicates a cut-on wavelength of 495nm, meaning it starts transmitting at this wavelength, and a cut-off wavelength of 0nm, indicating it transmits all wavelengths below this point. This makes the FGL495M an ideal choice for applications that require longpass filtration at 495nm.

The filter's shape is that of a thin lens, which not only contributes to its compactness but also allows for easy integration into various optical setups. The FGL495M's current status is 'in stock', as indicated by its weblink, which is valid and functional.
