FESH0650 Dia:25.0 mm Premium Shortpass Filter; Cut-Off Wavelength: 650nm
The FESH0650 is a high-quality shortpass filter, manufactured by Thorlabs, with a diameter of 25.0 mm and a thickness of 3.5 mm. This filter is designed to transmit light with wavelengths shorter than the specified cut-off wavelength of 650nm, while blocking or reflecting light at longer wavelengths.
The FESH0650 features a circular shape and is made from UVFS, a material with the Mal-1965 identification. The filter's coating, applied to both the front and back surfaces, is designated as 'tho fesh0650'. This coating enhances the filter's performance, ensuring precise and reliable shortpass filtering.
The physical data of the FESH0650 indicates a cut-on wavelength of 0nm, suggesting that it begins transmitting light immediately at the shortest detectable wavelengths. This, combined with its 650nm cut-off wavelength, makes the FESH0650 a versatile tool for a wide range of optical applications.
