NE10A-A Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; SM1-Threaded Mount; 350-700nm; OD 1.0 AR 350-700nm

The NE10A-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 circular shape with a diameter of 25 mm and a thickness of 1.9 mm, making it suitable for a wide range of applications.

The NE10A-A filter features an absorptive design, which means it reduces light intensity by absorbing excess light, rather than reflecting it. This design ensures minimal reflection and scattering, contributing to improved image quality. The filter has an Optical Density (OD) of 1.0, which translates to a 10% transmission of light. This makes it ideal for applications where moderate light reduction is required.

The filter's coating is another notable feature. Both the front and back surfaces are AR-coated for the 350-700nm wavelength range. This Anti-Reflective coating reduces surface reflections, further enhancing the filter's performance and ensuring optimal light transmission.

The NE10A-A filter is mounted in an SM1-threaded mount, providing a secure and stable connection within your optical system. This mount is compatible with other SM1-threaded components, offering flexibility in system design.
