FELH1100 Dia:25.0 mm Premium Longpass Filter; Cut-On Wavelength: 1100nm
The FELH1100 is a premium longpass filter, part of the extensive catalog of optical elements offered by Thorlabs. This filter, with a catalog number FELH1100, is specifically designed for applications requiring a longpass filter with a cut-on wavelength of 1100nm.
The filter is circular in shape, with a diameter of 25.0 mm and a thickness of 3.5 mm, making it compatible with a wide range of optical systems. The FELH1100 features a thin lens shape, which is beneficial for applications where minimal thickness is a requirement.
The FELH1100 is made from UVFS material, identified as MAL-1965 in Thorlabs' database. The filter's coating, applied on both the front and back surfaces, is THo FELH01100. This coating ensures the filter's performance, specifically its longpass characteristics.
The filter's physical data includes a cut-on wavelength of 1100nm, indicating that it begins to transmit light at this wavelength and above. The cut-off wavelength is 0nm, meaning it blocks all wavelengths below 1100nm.
The FELH1100 is currently in stock and available for purchase through Thorlabs' website. For more information, users can visit the provided weblink: https://www.thorlabs.com/thorproduct.cfm?partnumber=FELH1100.
