FGUV5M Dia:25 mm UG1 Colored Glass Bandpass Filter; SM1-Threaded Mount
The FGUV5M is a color glass bandpass filter developed by Thorlabs, a leading global manufacturer of photonics equipment. This filter, with a catalog number FGUV5M, is specifically designed for applications requiring precise wavelength selection. The filter features an SM1-threaded mount for easy integration into optical systems.
The FGUV5M filter is made from high-quality n-BK7 Schott glass, a material known for its excellent optical properties. It has a circular shape with a diameter of 25 mm and a thickness of 2 mm, making it suitable for a wide range of applications.
The filter's primary function is to transmit light within a specific wavelength range while blocking unwanted wavelengths. The FGUV5M is designed to transmit light at a central wavelength of 588 nm. It has a cut-on wavelength of 240 nm and a cut-off wavelength of 395 nm, providing a narrow bandwidth for precise wavelength selection.
The filter's front and back surfaces are coated with a special Thorlabs coating, denoted as tho fguv5. This coating enhances the filter's performance by reducing reflection and increasing transmission efficiency. The filter's shape is that of a thin lens, further enhancing its optical performance.
