FGUV11-UV Dia. 25 mm UG11 Colored Glass Filter; AR Coated 245-400nm
The FGUV11-UV is a color glass filter, manufactured by Thorlabs, with a catalog number FGUV11-UV. This filter is designed with a circular shape, featuring a diameter of 25 mm and a thickness of 2 mm. The filter's primary material is n-bk7 schott, a well-known optical glass.
The FGUV11-UV filter is specifically designed for use in the ultraviolet region of the spectrum, with a cut-on wavelength of 245 nm and a cut-off wavelength of 400 nm. This makes it ideal for applications that require the removal or isolation of UV light.
The filter is coated on both the front and back surfaces with an anti-reflection (AR) coating, identified as tho fguv11-uv. This coating is designed to reduce surface reflections, thereby improving transmission and minimizing back reflections. The AR coating is effective over a wide range of wavelengths, from 245 nm to 400 nm.
The filter's shape is classified as a thin lens, suggesting that it may have some degree of lens-like behavior, although this is not explicitly stated in the provided data. However, it is clear that this filter is designed to provide high-quality optical performance in the UV region of the spectrum.
