84-763 50 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=5 mm 850nm
The 84-763 is a high-performance longpass filter, boasting a 50 mm diameter and a thickness of 5 mm, sourced from the reputable vendor Edmund Optics. This filter is designed with a cut-on wavelength of 850 nm, making it ideal for applications that require the transmission of infrared light.
The filter's construction comprises a base shape of a circular Thin Lens, ensuring efficient light transmission and minimal distortion. The material ID, uvfs mal- 1965, indicates the specific material used in the filter's construction, although the exact composition is not detailed in the provided data.
The 84-763 filter features hard coating on both the front and back surfaces, denoted as edm 66-228. This coating enhances the filter's durability and resistance to wear and tear, making it suitable for rigorous use in various applications.
The physical data of the filter indicates a cut-off wavelength of 0 nm, suggesting that the filter allows all wavelengths below the cut-on wavelength to pass through. This characteristic is particularly useful in applications where a wide range of infrared wavelengths need to be transmitted.
