NE04A-A Dia. 25 mm AR-Coated Absorptive Neutral Density Filter; SM1-Threaded Mount; 350-700nm; OD 0.4 AR 350-700nm
The NE04A-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 0.7 mm, making it suitable for a wide range of applications.
The filter is made from UVFS material, identified by the Mal-1965 material ID, and has a wavelength of 633 nm. It features an AR coating on both the front and back surfaces, specifically designed for the 350-700 nm range. This coating helps to minimize reflections and increase transmission, thereby enhancing the overall performance of the optical system.
The NE04A-A filter is mounted in an SM1-threaded mount, providing a secure and stable platform for integration into your optical system. The mount is compatible with other SM1-threaded components, offering flexibility in system design.
