FELH1450 Dia:25.0 mm Premium Longpass Filter; Cut-On Wavelength: 1450nm
The FELH1450 is a premium longpass filter, part of the extensive catalog of optical elements offered by Thorlabs. This filter, with a catalog number FELH1450, is specifically designed for applications where a longpass filter with a cut-on wavelength of 1450nm is required.
The filter is circular in shape, with a diameter of 25.0 mm and a thickness of 3.5 mm, making it suitable for a wide range of optical setups. The FELH1450 is made from UVFS MAL-1965, a material known for its optical properties and durability.
The coating on both the front and back of the filter is THo FELH01450, which is specifically designed to provide a sharp cut-on at 1450nm. This coating ensures that the filter allows transmission of wavelengths longer than 1450nm while effectively blocking shorter wavelengths.
The FELH1450 is available directly from Thorlabs, and the link provided in the item data indicates that it is currently in stock. This information, along with the detailed specifications, should help users in their selection process when looking for optical components with similar properties.
