NE03B-B Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; 650-1050nm; OD 0.3 AR 650-1050nm

The NE03B-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 0.3, which means it reduces the intensity of the incident light by a factor of 2 (50% transmission).

The NE03B-B filter features Anti-Reflection (AR) coatings on both the front and back surfaces, specifically designed for the 650-1050nm wavelength range. These coatings help to minimize reflection and increase transmission, thereby improving the overall performance of the filter. The filter has a thickness of 2.3 mm, which is considered thin for this type of optical component.

The filter's shape is described as a Thin Lens, which suggests that it has been designed to minimize optical aberrations. This is particularly important in applications where high-precision optical alignment is required. The filter is made from UVFS material, which is known for its excellent optical properties and durability.
