FGUVM Dia:25 mm BG36 Colored Glass Bandpass Filter; SM1-Threaded Mount
The FGUVM Dia:25 mm BG36 Colored Glass Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Thorlabs. This filter features a 25 mm diameter and a 2 mm thickness, making it suitable for a wide range of applications.
The filter is made from n-bk7 Schott glass, a material known for its excellent optical properties and durability. It is designed to transmit light within a specific wavelength range, with a peak transmission at 588 nm. The cut-on wavelength is 325 nm, and the cut-off wavelength is 385 nm, providing a narrow bandwidth for effective wavelength selection.
The FGUVM filter is coated with a proprietary coating, referred to as 'tho fguv', on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall signal-to-noise ratio.
The filter is mounted in an SM1-threaded mount, which allows for easy integration into optical systems that use SM1 (1.035-32) components. This mount ensures secure and stable positioning of the filter, reducing the risk of misalignment and ensuring optimal performance.
