NENIR220B 2 in x 2 in Unmounted NIR Absorptive ND Filter; OD 2.0

The NENIR220B is a 2 in x 2 in Unmounted Neutral Density (ND) Filter, specifically designed for Near-Infrared (NIR) applications with a center wavelength of 1550 nm. This filter is sourced from Thorlabs, a renowned vendor known for its high-quality optical components.

The filter is made of UVFS material, identified by the Mal-1965 material ID. It features a thin lens shape, with a width, height, and thickness of 50.8 mm, 50.8 mm, and 1.3 mm respectively. This compact size makes it suitable for various optical setups where space is a constraint.

The NENIR220B filter boasts a coating on both the front and back surfaces, identified as 'tho nenir20b'. This coating is designed to provide a high level of neutral density, with an Optical Density (OD) of 2.0. This means it reduces the intensity of the incident light by a factor of 100, making it an ideal choice for high-intensity NIR applications.

The filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems using their preferred mounting solution. The 'weblink status' indicates that the filter is currently in stock, ensuring quick delivery for your optical needs.
