FGB25 Dia. 25 mm BG3 Colored Glass Bandpass Filter; 315-445nm and 715-1095nm

The FGB25 is a high-quality bandpass filter from Thorlabs, designed with a diameter of 25 mm and a thickness of 2 mm. This filter is made of n-BK7 Schott, a durable and optical-quality glass, and features a base shape of a circle.

The FGB25 is designed to transmit light within specific wavelength ranges while blocking other wavelengths. It has a cut-on wavelength of 315 nm and a cut-off wavelength of 445 nm, making it ideal for applications that require the transmission of light in the ultraviolet and blue regions of the spectrum.

Additionally, the FGB25 has a secondary transmission range, with a cut-on wavelength of 715 nm and a cut-off wavelength of 1095 nm. This makes it suitable for applications that require the transmission of light in the near-infrared region of the spectrum.

The filter is coated with a special coating, denoted as 'tho fgb25' on both the front and back surfaces, which enhances its performance and durability. The shape of the filter is that of a thin lens, which further adds to its functionality and versatility.
