NENIR206B 2 in x 2 in Unmounted NIR Absorptive ND Filter; OD 0.6

The NENIR206B 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 reputable vendor known for its high-quality optical components.

The filter is made of UVFS material, identified by the Mal-1965 code, and features a thin lens shape. It has a uniform thickness of 1 mm, making it suitable for various optical systems. The NENIR206B filter is coated with the THo NENIR06B coating on both the front and back surfaces, providing an Optical Density (OD) of 0.6. This coating is designed to absorb a significant portion of the incident light, reducing the intensity without altering the color composition.

The filter's geometry is rectangular, with a width and height of 50.8 mm each. This size is a standard in the industry, allowing it to fit into most optical systems that accommodate 2 in x 2 in filters. The filter is unmounted, providing users with the flexibility to integrate it into their systems using their preferred mounting solution.

The filter's status is "Valid - in stock" as of the time of data collection, indicating its availability for immediate purchase and delivery. The product's webpage is also provided, offering more detailed information and specifications for those interested.
