NENIR530B Dia. 0.5 in NIR Absorptive ND Filter; OD 3.0

The NENIR530B is a Neutral Density (ND) Filter, specifically designed for use in the near-infrared (NIR) spectrum with a wavelength of 1550 nm. This filter, sourced from Thorlabs, is a crucial component in various optical systems where light intensity needs to be controlled or reduced without altering the color composition.

The filter is circular in shape, with a diameter of 12.7 mm and a thickness of 2 mm, making it compatible with a wide range of optical systems. It features a thin lens shape, which is beneficial in maintaining the overall optical path length and minimizing aberrations.

The NENIR530B is coated with Thorlabs' proprietary NENIR30B coating on both the front and back surfaces. This coating provides an Optical Density (OD) of 3.0, which translates to a reduction of 99.9% of the incident light at the specified wavelength. This high attenuation level makes it suitable for applications requiring significant light reduction.

The filter is currently in stock and available for immediate purchase through the vendor's website. For more information, please refer to the provided weblink.
