FGL850 Dia:25 mm RG850 Colored Glass Filter; 850nm Longpass

The FGL850 Dia:25 mm RG850 Colored Glass Filter is a high-quality optical component designed for longpass filtering at 850nm. This filter is sourced from the renowned vendor Thorlabs, a leading manufacturer in the optical industry. The filter is characterized by its circular shape, with a diameter of 25mm and a thickness of 2mm, making it suitable for a wide range of optical applications.

The FGL850 filter is made from n-bk7 Schott, a high-grade optical glass known for its excellent transmission properties and durability. The filter's primary function is to cut on at 850nm, allowing light of this wavelength and longer to pass through while blocking shorter wavelengths. This makes it ideal for applications where specific wavelength filtration is required.

The filter's coating is another notable feature. Both the front and back surfaces are coated with the THo FGL850 coating, which enhances the filter's performance and durability. The coating ensures optimal light transmission and reduces surface reflections, thereby improving the overall efficiency of the optical system.
