62-678 50 mm Dia. NIR Metallic Based Neutral Density Filter; OD 1.5 700-1100nm

The 62-678 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 manufactured by Edmund Optics, a leading provider of optical components. The filter is part of their extensive catalog, which includes a wide variety of optical elements from different vendors worldwide.

The filter is metallic based, which provides excellent durability and stability. It has an Optical Density (OD) of 1.5, which means it reduces the intensity of the incident light by a factor of 3.16. This is particularly useful in applications where controlling the light intensity is crucial.

The filter is coated with EDM 47-829 on both the front and back surfaces. This coating enhances the filter's performance in the NIR spectrum, providing high transmittance and low reflectance. The coating also provides excellent environmental stability, ensuring the filter maintains its performance over time.

The filter has a thin lens shape, which minimizes optical aberrations and distortions. The geometry of the filter includes a diameter of 50 mm and a thickness of 5 mm, making it suitable for a wide range of optical systems.

The filter is currently in stock and available for purchase through the Edmund Optics website. The weblink provided leads directly to the product page, where more information about the filter, including its specifications and pricing, can be found.
