Classification: CPC G  B  C | IPC B  C  G

Claim 12:
13. Optical apparatus comprising:
a stock of optical MEMS elements, without any QWP coating, to which, subsequently, has been added, according to customers' needs, QWP coatings, the stock including:
diced optical mems elements E1 selected from the stock, each of which elements E1 includes N1 optical elements where N1 is the number of optical elements required by an order O1, and active optical coatings that achieve requirements of said order O1, are deposited atop each of the diced optical MEMS elements E1 to fill order O1; and
diced optical mems elements E2 selected from the stock, each of which elements E2 includes N2 optical elements where N2 is the number of optical elements required by an order O2; and active optical coatings that achieve requirements of said order O2, are deposited atop each of the diced optical MEMS elements E2 to fill order O2,
wherein at least one of said active optical coatings comprises a QWP coating
wherein the optical apparatus also includes a hard mask used to add QWP coating to the MEMS chips as pre-prepared,
wherein the hard mask is aligned to at least one MEMS element under a microscope, and
wherein at least one MEMS element is pushed, under a microscope, under the hard mask including performing microscopic-level alignment of the MEMS element with the hard mask.
