NE06B Dia. 25 mm Absorptive ND Filter; Optical Density 0.6

The NE06B is a Neutral Density (ND) Filter, measuring 25 mm in diameter and 1.1 mm in thickness, manufactured by Thorlabs. This filter is designed to reduce the intensity of incident light without altering its color composition, making it an ideal choice for applications requiring controlled light exposure.

The filter's core is made of n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including low auto-fluorescence and high transmittance across a broad spectrum. This material ensures the filter maintains high image fidelity and color accuracy.

The NE06B features a front and back coating of tho ne06a, an advanced absorptive coating technology developed by Thorlabs. This coating provides an optical density of 0.6, which translates to a reduction of 40% of the incident light. This specific optical density is suitable for applications requiring moderate light reduction without introducing significant optical artifacts.

The filter's thin lens shape allows for easy integration into various optical systems, while its circular geometry provides versatility in mounting and alignment. The filter's catalog number, NE06B, can be used to access additional information or place orders directly from Thorlabs' official website.
