NENIR20B-C Dia. 25 mm Unmounted AR-Coated Absorptive Neutral Density Filter; 1050 - 1700nm; OD 2.0 AR 1050-1700nm

The NENIR20B-C is a circular, unmounted neutral density filter, designed for use in the 1050 - 1700nm wavelength range. This filter is manufactured by Thorlabs, a leading global supplier of photonics equipment. The NENIR20B-C features an optical density (OD) of 2.0, providing a significant reduction in light intensity while maintaining color neutrality.

The filter is constructed with a 25mm diameter and a thickness of 1.3mm, making it suitable for a wide range of optical applications. It boasts an anti-reflection (AR) coating on both the front and back surfaces, specifically designed for the 1050 - 1700nm wavelength range. This coating helps to minimize surface reflections, thereby improving transmission and reducing the risk of unwanted ghosting or flare.

The NENIR20B-C filter is part of Thorlabs' NENIR series, which is known for its high-quality, broadband absorptive neutral density filters. These filters are ideal for applications that require precise control over light intensity, such as laser applications, biomedical imaging, and astronomical observations.

The filter comes unmounted, providing users with the flexibility to integrate it into their existing optical systems.
