NE03A-A Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; SM1-Threaded Mount; 350-700nm; OD 0.3 AR 350-700nm

The NE03A-A is a Neutral Density Filter, specifically designed for use in optical systems where light intensity needs to be reduced without altering the color composition of the light. This filter, sourced from Thorlabs, boasts a 25 mm diameter and a thickness of 2.3 mm, making it suitable for a wide range of applications.

The NE03A-A filter features an absorptive design, which means it reduces light intensity by absorbing excess light rather than reflecting it. This design ensures minimal loss of light and reduces the risk of unwanted reflections. The filter is coated on both the front and back surfaces with an anti-reflective coating (AR 350-700nm), which further enhances its performance by minimizing surface reflections.

This filter is designed for use within the wavelength range of 350-700nm, making it suitable for a wide range of applications, from visible light to near-infrared. It is mounted in an SM1-threaded mount, which allows for easy integration into existing optical systems.

The NE03A-A filter is currently in stock and available for immediate purchase from the Thorlabs website. For more information, please refer to the provided weblink.
