The 62-679 is a 50 mm diameter Neutral Density Filter, specifically designed for use in the Near-Infrared (NIR) spectrum with a wavelength of 588 nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock with a valid web link for direct purchase.
The filter is circular in base shape and constructed from UVFS material with the Mal-1965 ID. It features a thin lens shape, ensuring minimal distortion and a compact design. The geometry of the filter includes a 50 mm diameter and a thickness of 5 mm, providing a robust and manageable size for various applications.
The 62-679 filter is coated with EDM 47-830 on both the front and back surfaces. This coating enhances the filter's performance in the NIR spectrum, providing an Optical Density (OD) of 2 for wavelengths between 700 and 1100 nm. This makes it an ideal choice for applications requiring significant light reduction in the NIR range.
