FGS900-A Dia. 25 mm KG3 Colored Glass Filter; AR Coated 350-700nm
The FGS900-A is a color glass filter manufactured by Thorlabs, a leading global supplier of photonics equipment. This filter, with a catalog number FGS900-A, is part of Thorlabs' extensive catalog of optical elements. The filter is currently in stock and can be purchased directly from Thorlabs' website.
The FGS900-A is a circular filter with a diameter of 25 mm and a thickness of 2 mm. It is made of n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. The filter is designed to transmit light at a central wavelength of 588 nm, making it suitable for applications that require precise wavelength control.
The FGS900-A is coated with an anti-reflection (AR) coating on both the front and back surfaces. This coating, designated as tho fgs900-a, is designed to reduce reflection and increase transmission across the 350-700 nm spectral range. The AR coating ensures that the filter performs optimally in a wide range of applications, from fluorescence microscopy to laser spectroscopy.
The filter has a thin lens shape, which is ideal for applications that require a compact, lightweight optical component. Despite its thin profile, the FGS900-A is robust and durable, making it suitable for use in a variety of environments.
