CD-5000: Ultra-Thin Color Compensating Filter

HOYA's CD-5000 is being developed as a next generation Ultra-Thin Color Compensating Filter for various imaging applications. At standard thickness of 0.45mm the optical properties of CD-5000 are equivalent to its predecessor C-5000 at 1.2mm thickness.

This filter is ideally suited for CCD applications such as Video Camera and Digital Camera. CD-5000 enhances the color distribution in the visible spectrum while eliminating any UV and near IR transmission.
