66-227 12.5 mm Dia. High Performance OD 4.0 Longpass Filter; t=2 mm 800nm
The 66-227 is a high-performance longpass filter, boasting a 12.5 mm diameter and a thickness of 2 mm. This filter, offered by Edmund Optics, is designed to transmit light with wavelengths above 800 nm, making it ideal for applications that require the removal of shorter wavelengths.
The filter is constructed from UVFS Mal-1965, a material specifically chosen for its optical properties. It features a circular base shape, ensuring easy integration into various optical systems. The 66-227 is coated on both the front and back surfaces with EDM 66-227, a coating that enhances its performance and durability.
This longpass filter is designed in the shape of a thin lens, which can be beneficial in certain optical configurations. The physical data of the filter indicates a cut-on wavelength of 800 nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0 nm, indicating that it blocks all wavelengths below this point.
The catalog number for this item is 66-227, and it is currently in stock. For more information or to make a purchase, users can visit the provided weblink: https://www.edmundoptics.com/p/800nm-125mm-dia-high-performance-longpass-filter/20745/.
