ND2R01A Dia. 50 mm Reflective ND Filter; SM2-Threaded Mount; Optical Density 0.1

The ND2R01A 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 applications involving high-intensity light sources.

The filter is made from N-BK7 Schott glass, a material known for its excellent optical properties and durability. It features a thin lens shape, with a thickness of 2 mm, ensuring minimal distortion and maintaining the integrity of the optical path.

The ND2R01A is coated with THo ND01 on both the front and back surfaces. This coating is designed to further reduce light transmission, ensuring optimal performance. The coating also provides scratch resistance, enhancing the longevity of the filter.

The filter is mounted with an SM2-threaded mount, providing a secure and stable connection to your optical system. The mount is compatible with a wide range of Thorlabs components, offering flexibility in system design.

The filter's optical density is 0.1, indicating that it reduces the light intensity to approximately 90% of the original intensity. This makes it suitable for applications requiring a moderate reduction in light intensity.
