ND06B Dia. 25 mm Unmounted Reflective ND Filter; Optical Density 0.6

The ND06B is a circular Neutral Density (ND) filter, unmounted and with a diameter of 25 mm, 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 ideal tool for various applications in photography, cinematography, and scientific research.

The filter features a uniform coating of ND06 on both the front and back surfaces, which corresponds to an Optical Density (OD) of 0.6. This specific density reduces the light intensity by a factor of √2, or approximately 40.8%. The ND06B filter is made of N-BK7 Schott glass, a material known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and superior transmittance in the visible spectrum.

The ND06B filter has a thickness of 1 mm and follows the thin lens shape, ensuring minimal optical aberrations and distortions. This filter is currently in stock and available for immediate shipping, as indicated by its weblink status.
