Attention! You can customise this product to your needs.
Circular ND filters provide continuously variable, linear attenuation of light by rotating the filter around its center. The filter can be used for white light as well as for lasers, or with any other source of light where signal attenuation is required. Transmitted intensity varies as a function of the optical density. For convenience every standard filter comes with mount as one set, but both items can be purchased separately. Standard filters come in diameters from 25 mm to 100 mm.
