FGB7 Dia. 25 mm BG7 Colored Glass Bandpass Filter; 435-500nm
The FGB7 Dia. 25 mm BG7 Colored Glass Bandpass Filter is a high-quality optical component sourced from Thorlabs. This filter is designed for use in applications that require the transmission of light within a specific wavelength range, in this case, 435-500nm.
The filter is made from N-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. It has a circular shape with a diameter of 25mm and a thickness of 2mm, making it suitable for a wide range of optical systems.
The FGB7 filter features a thin lens shape, which helps to minimize optical aberrations and ensures high-quality image transmission. The front and back surfaces of the filter are coated with the THo FGB7 coating, which is specifically designed to enhance the performance of the filter within its specified wavelength range.
The physical data of the filter indicates a cut-on wavelength of 435nm and a cut-off wavelength of 500nm. This means that the filter will block or attenuate light outside of this range, while allowing light within the range to pass through with high transmittance.
