NDIR30A Dia. 25 mm; SM1-Threaded Mount; IR Reflective Neutral Density Filter; OD 3.0

The NDIR30A is a Neutral Density Filter, offered by Thorlabs, with a catalog number NDIR30A. This filter is designed for use in the infrared spectrum, specifically at a wavelength of 5000 nanometers. It features a circular geometry with a diameter of 25 millimeters and a thickness of 1 millimeter, making it suitable for a wide range of optical applications.

The NDIR30A is constructed with a front and back coating of tho ndir30a, which provides excellent reflectivity in the infrared region. This coating is applied to a base material of znse marple-1964, ensuring durability and longevity. The filter is mounted with an SM1 thread, providing a secure and stable fit in your optical setup.

This filter has a high optical density (OD) of 3.0, which means it reduces the intensity of incident light by a factor of 1000. This makes it an ideal choice for applications where high light attenuation is required, such as in high-power laser systems or in applications where precise control over light intensity is necessary.

The NDIR30A is currently in stock and available for purchase through the Thorlabs website. For more information, please refer to the provided weblink: https://www.thorlabs.com/thorproduct.cfm?partnumber=NDIR30A
