NDW10B Dia. 25 mm Reflective ND Filter; Optical Density 1.0
The NDW10B 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 an ideal tool for maintaining consistent exposure levels in various lighting conditions.
The filter features a uniform optical density of 1.0, which corresponds to a reduction of 2.5 stops in light intensity. This makes it suitable for a wide range of applications, from photography and cinematography to scientific research and machine vision.
The NDW10B is made from N-BK7 Schott glass, a high-quality material known for its excellent optical properties. The filter's thin lens shape and 1 mm thickness contribute to its compact design, making it a convenient option for systems with limited space.
Both the front and back surfaces of the filter are coated with Thorlabs' NDW10B coating, which enhances its light reduction capabilities and ensures durability. The filter's geometry and coating make it compatible with a variety of optical systems, including those operating at a wavelength of 633 nm.
