NE05B-B Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; 650-1050nm; OD 0.5 AR 650-1050nm
The NE05B-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 0.5, which means it reduces the intensity of the incident light by a factor of 10^0.5, or approximately 3.16 times.
The NE05B-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 losses and improve transmission efficiency. The filter has a thickness of 0.9 mm, which is considered thin in the context of optical components.
The filter's shape is described as a Thin Lens, which suggests that it has been designed to focus or disperse light in a specific way. This could be useful in applications where precise control over the light path is required.
The NE05B-B filter is currently in stock and available for purchase through the Thorlabs website. Further information, including technical specifications and pricing, can be found on the product page linked below.
