Lens inspection
Most of the lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. Optical resin lenses have strong impact resistance and low price, and are currently widely used lenses. Resin is a chemical substance with phenolic structure, which is easily deformed and affects optical performance. The customer wants to detect whether the lens is deformed, which will help improve product quality.
The lens that the customer needs to detect is about a dime, and the lens is transparent and has a range, requiring complete scanning and high data accuracy. The traditional scanning method is difficult to scan, the accuracy of acquiring data is not high, and the effect is poor. It is necessary to use a new three-dimensional scanning technology to scan.

According to customer needs and workpiece conditions, Hualang technical engineers quickly gave a solution: use HOLON751 handheld 3D scanner.

Field STL data map
Since the lens is transparent, you need to spray a layer of powder on the surface first. Then use the handheld 3D scanner to perform comprehensive and fast scanning to obtain high-precision data, compare and analyze the original digital model on the 3D inspection software, and generate an intuitive data analysis report, which is recognized by customers.
