84-762 50 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=5 mm 800nm
The 84-762 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 to transmit light with wavelengths above 800 nm, making it ideal for applications that require the separation of infrared light.
The filter is constructed with a circular base shape, crafted from UVFS Mal-1965 material, and features a thin lens design. The front and back surfaces of the filter are coated with EDM 66-227, a hard coating that enhances durability and resistance to wear and tear, ensuring longevity and reliability in various conditions.
The 84-762 filter is designed with a cut-on wavelength of 800 nm, meaning it begins to transmit light at this wavelength. The cut-off wavelength is 0 nm, indicating that it allows all wavelengths below 800 nm to pass through. This specificity in wavelength transmission makes it a valuable tool for applications that demand precise light filtration.
The filter's physical data, including its diameter and thickness, contribute to its performance and usability. With a diameter of 50 mm, it provides a generous aperture for light to pass through, while its thickness of 5 mm ensures structural integrity and stability.
