In today's industrial manufacturing and quality inspection fields, precision measurement technology is like eyes that penetrate the microcosm, whose importance is self-evident. Thus, optical-based image measurement technology has emerged, gradually evolving into two distinct yet complementary technical paths represented by VMM and flash measuring instruments respectively. Although both belong to the optical measurement family, they differ significantly in technical principles, application scenarios, and performance focuses.

Over four decades of evolution, image measurement technology has transitioned from laboratories to industrial settings. Manufacturers like Sinowon have achieved sub-micron precision through continuous innovation, transforming China from a technology follower to a global innovator in the industry. Today, advancements such as AI-enhanced software algorithms, non-contact high-ratio optical zoom lenses, multi-field-of-view telecentric lenses, point-spectrum probes, 3D line-scan cameras, and fourth-axis electric rotary stages are converging on image measurement platforms. These integrations have elevated image measurement systems into indispensable industrial inspection tools, delivering increasingly powerful capabilities for modern manufacturing.

There are 5 series of manual and semi-automatic type among Sinowon vision measuring machine, it is iMove, iVision, iFocus, iTouch and iSemi.

Sinowon customizes the non-standard automatic measuring machine MVS-5040 with hydraulic glass cover for Korean customer, it is applied to measure the film material.
