The NE10B-A is a Neutral Density Filter with a diameter of 25 mm, manufactured by Thorlabs. This filter is designed for use within the wavelength range of 350-700nm, making it suitable for a wide range of optical applications. The filter has a thickness of 1.9mm, which is relatively thin, reducing the risk of vignetting and ensuring ease of integration into optical systems.
The NE10B-A filter features Anti-Reflection (AR) coatings on both the front and back surfaces. These coatings are specifically designed for the wavelength range of 350-700nm, further enhancing the filter's performance within this spectrum. The AR coatings help to minimize surface reflections, thereby improving transmission and reducing the risk of unwanted optical artifacts.
The filter is shaped as a Thin Lens, which can be beneficial in certain optical configurations. The catalog number for this filter is NE10B-A, and it can be found on the Thorlabs website, where it is currently in stock. This filter is made from UVFS material, as indicated by the Material ID.
