NE03A Dia. 25 mm Absorptive ND Filter; SM1-Threaded Mount; Optical Density 0.3
The NE03A is a Neutral Density (ND) Filter, offered by Thorlabs, with a diameter of 25 mm and a thickness of 2.3 mm. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an essential tool for various optical applications.
The filter is made from n-BK7 Schott, a high-quality optical glass, and features a thin lens shape. It comes with an SM1-threaded mount, providing compatibility with a wide range of optical systems. The NE03A filter boasts a front and back coating of 'tho ne03a', which enhances its performance and durability.
The optical density of this filter is 0.3, which means it reduces the light intensity to approximately 50% of its original value. This makes it suitable for applications where a moderate reduction in light intensity is required.
