NE503A Dia. 0.5 in Absorptive ND Filter; SM05-Threaded Mount; Optical Density 0.3
The NE503A is a Neutral Density (ND) Filter from Thorlabs, designed with a circular shape and a diameter of 0.5 inches. This filter is made from n-bk7 Schott material, a common choice for its excellent optical properties. It has a thickness of 2.3 mm, making it suitable for a wide range of optical applications.
The NE503A filter features a thin lens shape and is equipped with an SM05-threaded mount for easy integration into optical systems. The front and back of the filter are coated with tho ne03a, a specialized coating that enhances its performance and durability.
This filter is specifically designed for a wavelength of 633 nm, making it ideal for applications that require precise control over light intensity at this wavelength. The optical density of 0.3 indicates the amount of light that the filter will absorb, providing a useful tool for managing light levels in your optical setup.
The NE503A is currently in stock and available for purchase through the Thorlabs website. For more information, you can visit the product page at https://www.thorlabs.com/thorproduct.cfm?partnumber=NE503A.
