FGB37 Dia. 25 mm BG40 Colored Glass Bandpass Filter; 335-610nm

The FGB37 is a color glass bandpass filter, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This filter is characterized by its circular shape, with a diameter of 25 mm and a thickness of 2 mm, making it suitable for a wide range of optical applications.

The filter's primary function is to transmit light within a specific wavelength range, while blocking other wavelengths. The FGB37 is designed to transmit light between 335 and 610 nm, making it ideal for applications that require the transmission of blue and green light. The cut-on wavelength is 335 nm, and the cut-off wavelength is 610 nm, ensuring a high level of transmission efficiency within this range.

The FGB37 features a coating on both the front and back surfaces, identified as 'tho fgb37'. This coating enhances the filter's performance and durability, providing reliable and consistent optical performance. The filter's shape is described as a thin lens, further expanding its potential applications in optical systems.
