NENIR260B 2 in x 2 in Unmounted NIR Absorptive ND Filter; OD 6.0

The NENIR260B 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 2.8 mm respectively. This compact size makes it suitable for various optical setups where space is a constraint.

The NENIR260B filter boasts a high Optical Density (OD) of 6.0, providing significant attenuation of the incident light. This feature is particularly useful in high-power NIR applications where controlling the intensity of the light is crucial.

The filter is coated with Thorlabs' proprietary NENIR60B coating on both the front and back surfaces, ensuring high absorption across the NIR spectrum. This coating enhances the filter's performance, making it an ideal choice for NIR applications.

The filter is unmounted, providing users with the flexibility to integrate it into their existing optical systems. However, users should exercise caution while handling and mounting the filter to prevent damage.
