Comparing with the writing method of plane pattern  spherical pattern' has some remarkable different on several points. Firstly  it is difficult to spin-coated a uniform photoresist film on a spherical substrate  especially the ratio of spherical radius to caliber is smaller  and the spin-coated way must match the ratio of spherical radius to caliber. Secondly  if the sphere couldn't be regarded as a plane  a so-called concentric optical scan movement way must be applied for the generation of spherical pattern  because the reflex of substrate will affect the quantity of illumination. Commonly  an alignment technique is indispensable with pattern generation of spherical surface by the concentric optical scan in order to ensure the orthogonal intersection of focusing laser beam and writing surface. Thirdly  a uniform velocity control must be considered for the laser direct writing method on a spherical substrate. Otherwise  the exposure time of photoresist will be different  and the line widths of pattern will be also different at different areas. Fourthly  commonly  because the errors of concentric machine and substrate surface shape are bigger  so focusing servo-control technique is also needful for writing a pattern on a spherical substrate. Focusing servo-control may keep the focal spot on the spherical surface by a focus detection and control system in the course of writing pattern. Using these techniques  we fabricated a line width of 7m and a period of 600m isometric mesh on the concave of a spherical substrate.

The saw tooth grooves of blazed grating ruled by ruling engine are formed by diamond tool which presses on the aluminum film evaporated on the substrate of optical glass or metal. The real shape of ruled saw tooth groove is different from that of the ideal groove and the ruling process indicates that there are the zero order planes  similar to the flat tops  on the grating grooves. The results of Fourier analysis for the real ruled grating featuring the zero order plane structure shows that the flat top width is an important factor for grating efficiency. Additionally  bigger pressure value loaded on the diamond tool and bigger lateral pressure value on the aluminum film will be benefit to the improvement of grating diffraction efficiency. Based on the grating interferometer  the high precision positioning control system of ruling engine guarantees the accuracy of the grooves space. High density blazed grating whose space is 0.83p.m is manufactured and its' grooves spaces are very equidistant and uniform under the view field of AFM. And the infrared blazed grating  whose diffraction efficiency in the first order is up to 97 percent  is ruled successfully also.
