NE503B-B Dia. 0.5 in AR-Coated Neutral Density Filter; 650-1050nm; OD 0.3 AR 650-1050nm
The NE503B-B is a Neutral Density Filter from Thorlabs, designed with a circular base shape and a diameter of 12.7 mm. This filter is made of UVFS material, specifically identified as MAL-1965, and has a thickness of 2.3 mm. It is designed to work with a wavelength of 633 nm.
The NE503B-B filter features AR coatings on both the front and back surfaces, specifically THo NE03B-B. This coating is optimized for the AR range of 650-1050 nm, providing excellent anti-reflection properties within this spectrum. The filter's shape is thin lens, which is ideal for applications that require minimal thickness and light weight.
The filter's Neutral Density properties are characterized by an Optical Density (OD) of 0.3. This means that the filter reduces the intensity of incident light by a factor of 2 (the square root of 10 to the power of OD). This makes it suitable for applications where a small amount of light attenuation is required.
The NE503B-B filter is currently in stock and available for purchase through the Thorlabs website. For more information, users can visit the provided weblink.
