NE60B Dia. 25 mm Absorptive ND Filter; Optical Density 6.0
The NE60B is a Neutral Density (ND) Filter, measuring 25 mm in diameter and 1.5 mm in thickness, sourced from the reputable vendor Thorlabs. This filter is designed with a circular base shape and constructed from the high-quality material, N-BK7 Schott, ensuring durability and reliability.
The NE60B filter features a unique coating on both the front and back, specifically the THo NE60A coating. This coating is responsible for the filter's impressive optical density of 6.0, which is achieved at a wavelength of 633 nm. This high optical density makes the NE60B particularly effective in reducing light intensity, making it an ideal choice for applications requiring significant light control.
The filter's geometry, including its diameter and thickness, is designed to accommodate thin lens applications. The detailed parameters and specifications provided in the item data offer users a comprehensive understanding of the filter's capabilities, aiding in the selection process for those seeking components with similar properties.
