FGL780M Dia. 25 mm SM1-Mounted Colored Glass Filter; 780nm Longpass
The FGL780M is a color glass filter, circular in shape, with a diameter of 25 mm and a thickness of 2 mm. Manufactured by Thorlabs, this filter is made of n-bk7 schott material and features a 780 nm longpass cut-on wavelength. The filter's coating, applied to both the front and back, is identified as 'tho fgl780'.
This filter is designed for use with SM1-mounted systems and is characterized by its thin lens shape. The FGL780M is currently in stock and available for purchase through the Thorlabs website. As a longpass filter, it allows transmission of wavelengths greater than 780 nm while blocking shorter wavelengths. This makes it suitable for various applications where specific wavelength selection is required.
