NENIR20A-C Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; SM1-Threaded Mount; 1050 - 1700nm; OD 2.0 AR 1050-1700nm
The NENIR20A-C is a Neutral Density Filter, designed and manufactured by Thorlabs, a leading vendor in the field of optical components. This specific model boasts a circular shape with a diameter of 25 mm and a thickness of 1.3 mm, making it compatible with a wide range of optical systems.
The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It is designed to operate at a wavelength of 1550 nm, making it suitable for applications that require precise control over light intensity at this specific wavelength.
The NENIR20A-C features an AR coating on both the front and back surfaces. This Anti-Reflective coating is optimized for the 1050 - 1700 nm range, reducing unwanted reflections and increasing transmission efficiency. The coating also helps to minimize surface scattering, thereby improving the overall performance of the filter.
The filter is mounted in an SM1-threaded mount, providing a secure and stable platform for integration into optical systems. This mount is compatible with a wide range of optical components, making it a versatile choice for many applications.
