ND2R05A Dia. 50 mm Reflective ND Filter; SM2-Threaded Mount; Optical Density 0.5
The ND2R05A is a Neutral Density Filter with a diameter of 50 mm and a thickness of 2 mm, designed for use with optical systems operating at a wavelength of 633 nm. Manufactured by Thorlabs, a leading vendor in the field of optical components, this filter is made from high-quality N-BK7 Schott glass, ensuring excellent optical performance.
The filter features a reflective coating, denoted as 'tho nd05' on both the front and back surfaces. This coating is designed to provide an Optical Density of 0.5, which reduces the intensity of incident light without altering its color balance. This makes it an ideal choice for applications where light intensity needs to be controlled, such as in photography, laser applications, or beam shaping.
The ND2R05A filter is mounted in an SM2-threaded mount, providing a secure and stable connection to your optical system. The SM2 thread is a common and versatile thread standard in optics, allowing compatibility with a wide range of optical components.
