The design parameters of the present invention provide an improved cut-off characteristic with grating widths larger than one-half of the filter period. The two dimensional phase grating filter of the present invention can also be utilized in other optical systems, such as an automatic focusing system, where it is desired to pass only a certain spacial frequency as a monitored signal for the automatic adjustment of the focus of the optical system.

Abstract: The present invention is directed to a method of preparing a substrate to improve the adherence of a metallic coating to the substrate and the product thereof. More particularly, a method of manufactiring a molded circuit board and unique circuit board produced thereby, is disclosed.

The high relief areas of the circuit board can be masked with a protective material. The plating additive can then be chemically etched from the grooved recessed area and holes, for example, by a hydrochloric acid bath.
