Abstract :
According to the development of bio-technology, the requirements of metrology in biochip measuring become more precise and noncontact measurement like optical detector or ultra wave sensor is plenty used in this field. Laser scanning technology is used in examine biochip for its characteristic of noncontact measurement, high performance and good sensitivities. This paper emphasis on the lens designed for micro meter focusing scanning for bio-medical systems. The scanner exploits the functional advantages and the optical system has small spot size, great linearity and large depth of focus. The optical design of the scanning lenses is discussed and the scanner fabrication is introduced.
