NE01B Dia. 25 mm Absorptive ND Filter; Optical Density 0.1

The NE01B is a Neutral Density (ND) Filter, measuring 25 mm in diameter and 0.6 mm in thickness, sourced from the renowned optical component manufacturer, Thorlabs. 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 NE01B filter features a circular shape, crafted from the high-quality optical glass, N-BK7 Schott. This material is known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and superior chemical resistance. The filter's thin lens shape ensures minimal distortion, providing clear and accurate optical transmission.

The filter's coating is another notable feature. Both the front and back surfaces are coated with the THo NE01A coating, which is an absorptive coating specifically designed for neutral density filters. This coating ensures a consistent and precise optical density of 0.1 across the entire visible spectrum, specifically at a wavelength of 633 nm.

The NE01B filter is currently in stock and available for immediate purchase through the Thorlabs website. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
