FGS900H 6 in x 6 in Square KG3 Colored Glass Bandpass Filter; 315-710nm

The FGS900H is a 6 in x 6 in Square KG3 Colored Glass Bandpass Filter, designed and manufactured by Thorlabs. This filter is specifically engineered to transmit light within the wavelength range of 315-710nm, while effectively blocking light outside this range. The FGS900H is a versatile tool for a variety of optical applications, particularly those requiring precise wavelength selection and light control.

The filter is constructed from high-quality n-bk7 Schott glass, a material known for its excellent optical properties and durability. It features a rectangular shape, with a width and height of approximately 152.4mm each, and a thickness of 3mm. This robust construction ensures the filter can withstand rigorous use and maintain its performance over time.

The FGS900H is coated with a proprietary coating on both the front and back surfaces, identified as 'tho fgs900'. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The coating also provides protection against environmental factors, further ensuring the filter's longevity and reliability.

The filter's physical data includes a cut-on wavelength of 315nm and a cut-off wavelength of 710nm. This means that it allows the passage of light with wavelengths between these two values, making it an ideal choice for applications that require specific wavelength selection.
