NENIR250B 2 in x 2 in Unmounted NIR Absorptive ND Filter; OD 5.0

The NENIR250B 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 a unique material, UVFS MAL-1965, and features a Thin Lens shape. It has a width and height of 50.8 mm each, and a thickness of 2.3 mm, making it a compact yet effective solution for various optical setups. The filter's coating, THONENIR50B, is applied on both the front and back surfaces, ensuring optimal performance and durability.

The NENIR250B provides an Optical Density (OD) of 5.0, which is equivalent to a transmission of 0.001%. This high attenuation level makes it ideal for applications that require significant light reduction, such as high-power laser systems or sensitive imaging applications in the NIR spectrum.

The filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems using their preferred mounting solution.
