Abstract

The invention discloses a digital microscopic optical imaging device with a long working distance, which consists of a microscope imaging light path and an industrial camera and belongs to the technical field of detection equipment. According to the invention, by simulating an optical imaging effect by utilizing optical design software ZEMAX, it provides a digital microscopic optical imaging device with a working distance of 400 mm, a view field range diameter of 4 mm, a working waveband of visible light, and a microscope optical system with a resolution of 10 [mu]m. The optical system has thecharacteristics of long working distance, high-resolution imaging and the like, and can be applied to non-contact detection in the industrial field.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to a long working distance digital microscopic optical imaging device. Background technique [0002] Microscopes are widely used. It can not only be used in the field of biology, but also play a pivotal role in other scientific fields such as medicine, astronomy, and materials science. It is precisely because the microscope plays such an important role that every innovation in the field of scientific research is inseparable from it. Therefore, the microscope has become an important symbol of scientific development and has been widely used in the detection field and industrial production. [0003] However, when the workpiece is in a relatively harsh environment, the microscope needs to perform high-resolution imaging on the surface of the measured workpiece at a long working distance to observe the changes of the sample to be tested, such as observing the thermal expansion of the metal. ...
