NE60B-B Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; 650-1050nm; OD 6.0 AR 650-1050nm

The NE60B-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 6.0, which means it reduces the intensity of the incident light by a factor of 10^6. This is particularly useful in high-intensity light situations where light levels need to be reduced to prevent damage to sensitive optical components or to allow for the use of longer exposure times.

The NE60B-B filter features Anti-Reflection (AR) coatings on both the front and back surfaces, with a specified coating material of 'tho ne60b-b'. These coatings help to minimize reflections and improve transmission, ensuring that the maximum amount of light passes through the filter. The filter has a thickness of 1.5 mm and a base shape of a circle, which is a common and versatile shape for optical components.

The filter's geometry and shape are designed for easy integration into optical systems. It has a 'Thin Lens' shape, which means it is thin relative to its diameter, reducing the risk of vignetting and improving the overall optical performance of the system. The NE60B-B filter is currently in stock and available for purchase through the Thorlabs website.
