CVND filters can be used for attenuation of white light and laser sources, maintaining light intensity consistency and calibration, large aperture attenuation, and can be used as a variable beamsplitter.

Yes, CVND filters can be fully customized in optical density gradient function, transmission gradient function, substrate type, coating materials, and size to match your application requirements.

A Circular Variable Neutral Density filter is a filter wheel that can linearly attenuate light as the filter is rotated.

CVND filters are available in sizes ranging from 25mm to over 200mm in diameter.

CVND gradients are available from 0 to 1, 2, 3, 4 or 5. Specify upon placing an order.
