NE60A Dia. 25 mm Absorptive ND Filter; SM1-Threaded Mount; Optical Density 6.0

The NE60A is a Neutral Density Filter by Thorlabs, designed with a circular shape and a diameter of 25 mm. This filter is made of n-bk7 schott material and has a thickness of 1.5 mm, providing excellent optical performance. The front and back of the filter are coated with tho ne60a, ensuring high-quality light absorption and maintaining consistent optical density.

The NE60A features an SM1-threaded mount, allowing compatibility with various optical systems and equipment. Its optical density is 6.0, making it highly effective at reducing light intensity without altering the color composition. This filter is ideal for applications requiring high attenuation, such as laser experiments, astronomical observations, or imaging in bright environments.

With a wavelength of 633 nm, the NE60A is suitable for use with a wide range of light sources. Its thin lens shape ensures minimal distortion and maintains the overall optical integrity of your system. The NE60A is currently in stock and available through the Thorlabs website, as indicated by its weblink status.
