FGS900 Dia. 25 mm KG3 Colored Glass Bandpass Filter; 315-710nm

The FGS900 is a color glass bandpass filter, boasting a diameter of 25 mm and a thickness of 2mm, sourced from the renowned optical component manufacturer, Thorlabs. This filter is designed to transmit light within a specific wavelength range, while blocking other wavelengths, making it an essential component in various optical systems.

The FGS900 filter is cut on at 315nm and cut off at 710nm, ensuring a precise range of wavelength transmission. This characteristic is particularly useful in applications where specific wavelength selection is required, such as in fluorescence microscopy, spectroscopy, and laser systems.

The filter is made of n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including high transmittance and low auto-fluorescence. This material ensures the filter's durability and reliability, making it suitable for rigorous optical applications.

The front and back of the FGS900 filter are coated with tho fgs900, a proprietary coating developed by Thorlabs. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The FGS900 filter features a thin lens shape, which is beneficial in applications where space is a constraint. This shape also minimizes optical aberrations, ensuring optimal image quality.

According to the vendor's website, the FGS900 filter is currently in stock, indicating its availability for immediate purchase and use. The filter's catalog number is FGS900, and it can be found on Thorlabs' official website for further details and specifications.
