an alternative objective, fitted with a 0.1 mm. scale and giving a magnification of 15, is obtainable. As the graticules may be ruled to any desired scale or pattern, the micrometer should prove useful as a test instrument in many industrial operations. It can easily be applied, for ...
optical axis is 22 micrometer. The rotationally symmetric aspherical shape is given by the equation: z(r)=B2ir21 (11) with z being the position of the surface along the optical axis in the direction of from the radiation source to the record carrier measured in millimeters, r the ...
In contrast, etching the writing gaps on a unitary structure incorporating both head portions allows the gaps to be positioned with photolithographic accuracy, which can be a few tenths of a micrometer or better. Forming the gaps together using photolithographic techniques recognizes that accurate ...
(that is, a synthetic or processed high molecular weight polymer that is, or is not, thermosetting or thermoplastic). Substrate10may have a thickness of at least 1 micrometer (or at least 5, 10 or 100 micrometers), or at least 1 mm. Substrate10may be transparent to the wavelength of ...
