NE02B-B Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; 650-1050nm; OD 0.2 AR 650-1050nm
The NE02B-B is a Neutral Density Filter with a diameter of 25 mm, manufactured by Thorlabs. This filter is designed for use in the 650-1050nm wavelength range, making it suitable for a wide range of optical applications. The filter has an Optical Density (OD) of 0.2, which means it reduces the intensity of the incident light by a factor of 1.26.
The NE02B-B filter features Anti-Reflection (AR) coatings on both the front and back surfaces. These coatings are specifically designed for the 650-1050nm wavelength range, further enhancing the filter's performance. The AR coatings help to minimize reflections, thereby improving transmission and reducing the likelihood of unwanted optical artifacts.
The filter has a Thin Lens shape and a thickness of 1.4 mm. It is made from UVFS material, as indicated by the Mal-1965 material ID. The catalog number for this filter is NE02B-B, and it can be found on the Thorlabs website, where it is currently in stock.
