NE13B-A Dia. 25 mm AR-Coated Neutral Density Filter; 350-700nm; OD 1.3 AR 350-700nm
The NE13B-A is a Neutral Density Filter with a diameter of 25 mm, manufactured by Thorlabs. This filter is designed to reduce the intensity of incident light without altering its color composition, making it ideal for applications involving high-intensity light sources.
The filter features an Anti-Reflection (AR) coating on both the front and back surfaces, specifically designed for the wavelength range of 350-700nm. This coating helps minimize surface reflections, thereby enhancing transmission and reducing the risk of unwanted ghost images.
The NE13B-A has a thickness of 2.5 mm and is shaped as a Thin Lens, which is beneficial for applications requiring precise optical alignment. The filter is made from UVFS material, identified by the Mal-1965 material ID.
This filter is currently in stock and available for immediate purchase through the Thorlabs website. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
