FESH0850 Dia:25.0 mm Premium Shortpass Filter; Cut-Off Wavelength: 850nm
The FESH0850 Dia:25.0 mm Premium Shortpass Filter is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This filter is designed with a base shape of a circle, making it universally applicable in various optical systems. The filter has a diameter of 25.0 mm and a thickness of 3.5 mm, ensuring durability and stability in its operation.
The filter is a Shortpass Filter, a type of optical filter that transmits short wavelengths and reflects or absorbs longer wavelengths. Specifically, this filter has a cut-off wavelength of 850nm, meaning it allows wavelengths shorter than 850nm to pass through while blocking those longer. This property makes it ideal for applications where the rejection of longer wavelengths is crucial.
The FESH0850 is made from UVFS Mal-1965, a material known for its optical properties. The filter is coated on both the front and back with the THo FESH0850 coating, enhancing its performance and durability. The shape of the filter is Thin Lens, indicating that it has been designed to focus or disperse light in a specific manner.
The filter is currently in stock and available for immediate purchase through the vendor's website. For more information, please refer to the provided weblink.
