NENIR06B Dia. 25 mm Unmounted NIR Absorptive ND Filter; OD 0.6

The NENIR06B is a circular, unmounted Neutral Density (ND) filter, specifically designed for use in the near-infrared (NIR) spectrum with a wavelength of 1550 nm. This filter is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.

The filter boasts a diameter of 25 mm and a thickness of 1 mm, making it a compact yet effective solution for various optical applications. It features a thin lens shape, which is beneficial for maintaining a streamlined optical path and minimizing unwanted reflections.

The NENIR06B filter is coated with a specialized NIR absorptive coating, denoted as 'tho nenir06b' on both the front and back surfaces. This coating is designed to absorb a significant portion of the incident NIR light, thereby reducing its intensity without altering the light's color balance. The coating's optical density (OD) is 0.6, which corresponds to a reduction in light intensity by a factor of 2.

The filter's catalog number is NENIR06B, and it is currently in stock, as indicated by its weblink status. For more information, users can refer to the provided weblink: 'https://www.thorlabs.com/thorproduct.cfm?partnumber=NENIR06B'.
