Disclosed is a three-dimensional adjustment mechanism for performing precise adjustment of an optical element in a high-resolution imaging system. The three-dimensional adjustment mechanism includes three elastic adjustment members uniformly distributed to conduct an axial displacement adjustment and a tilt adjustment of the optical element. The three elastic adjustment members are uniformly arranged at a bottom of the optical element, and configured to perform dynamic adjustment for the optical element with high precision on basis of deformations of the elastic adjustment members.

The present disclosure provides a high accuracy measurement system for focusing and leveling. The system determines an off-focus distance in the perpendicular direction within the exposure field and an inclination in the horizontal direction by measuring heights of four detection points on a substrate by using a four-channel detection method, thereby achieving focusing and leveling of the substrate. The detection of the substrate heights is implemented by a focusing method based on dual-channel light intensity modulation. Two superposed grating fringes are formed with phase difference of &#x3c0;/2. The shift can be resolved by the phase variation of corresponding fringes. According to the method, the off-focus distance can be derived. The present disclosure effectively eliminates the error due to the intensity changes caused by the fluctuations of the source or the reflectance of the substrate surface. The apparatus for focusing and leveling is easy to be implemented and has an accuracy of nanoscale.

A customizing equipment for individualized contact lenses comprises an uniform illumination system, a gray image generation system, a projection optical system, a stage system and an alignment system, among which the uniform illumination system generates uniform parallel illuminative light, which generates gray images through the gray image generator controlled by a computer after going through the gray image generation system according to detection results of aberration of human eyes, and images on the image plane of given radius of curvature with photoresist on the samples' surface, which is fixed on the stage system and adjusted to the correct position through the alignment system, after the gray images are zoomed and the curvature of the image field is corrected through the projection optical system, so that the photoresist on the samples' surface will be exposed according to the gray levels of the gray images, after which the exposed samples are developed and etched to obtain the device with continuous embossment microstructure on the sphere. After the checking and post-processing, this device will result in the individualized contact lenses, which can be worn. This current invention can realizes fast customization of individualized contact lenses.
