ND2R02A Dia. 50 mm Reflective ND Filter; SM2-Threaded Mount; Optical Density 0.2
The ND2R02A is a Neutral Density Filter with a diameter of 50 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 various optical applications. The filter features a uniform optical density of 0.2, providing a reduction of 1/3 in light intensity.
The ND2R02A is constructed from N-BK7 Schott glass, a material known for its excellent optical properties and durability. The filter's geometry includes a thickness of 2 mm, contributing to its robustness and stability. The front and back surfaces of the filter are coated with tho nd02, a reflective coating that enhances the filter's performance and longevity.
This filter is designed with a Thin Lens shape, which is characterized by a flat front and back surface, allowing for easy integration into optical systems. The filter is mounted with an SM2-threaded mount, providing a secure and stable connection to other optical components.
The ND2R02A is currently in stock and available for purchase through the Thorlabs website. For more information, please refer to the provided weblink.
