Blue light 3d scanners are perfect for scanning detailed features because of their accuracy and the nature of blue wavelength. Blue light is usually between 450 to 495 nanometers, therefore a very appropriate choice for scanning at high resolution. The wavelength is shorter than that of red light and this enables the scanner to shoot more accurate and clearer details. The more precise the wavelength, the more precise the finer details can be picked up by the scanner, down to microns, useful when scanning thin objects like sculptures, jewelry, or medical models.
In 2024, the revopoint MINI 2 3D scanner using blue light technology will be 0.02 mm single-frame precision, which is perfect for recording very fine detailed details that would be very hard for scanning technologies such as laser or infrared. The scanner also has a high accuracy of 0.05, which means even minute differences in surface texture and geometry are recorded perfectly. Such information is especially critical in manufacturing, art restoration, and dentistry industries, where small details are of utmost significance in the production and design process.
Blue light 3d scan works by projecting a series of blue light patterns on the subject. The scanner measures how the light changes as it is reflected off the surface, creating a very accurate 3d representation of the subject. While lasers are so sensitive that they can be disrupted by the reflectivity of the surface, blue light scanners are less susceptible to shiny or reflective surfaces, which is a huge benefit in scanning for materials such as plastics, metals, or glass.
One of the most amazing uses of blue light 3d scanning is what has been accomplished in the automotive industry. In 2024, automobile manufacturers like Ford used blue light scanners to scan engine components with unprecedented accuracy. The components were scanned at 0.02 mm resolution to enable accurate fitting during assembly, which is a testament to the importance of high detail scanning in manufacturing. Blue light technology helped make production more efficient, reduced error, and increased efficiency on the production line.
“Technology is most effective when it connects people,” says Matt Mullenweg, prominent technology entrepreneur, explaining how devices like 3d scanning narrow the precision and design differences. To companies that live and die on issues of fine detail, like aerospace or medicine, the ability to scan such fine features without distortion is paramount. Thus, blue light 3d scanner are increasingly becoming a necessary tool for prototyping and inspection, allowing designers and engineers to record even the most complex shapes and textures with unparalleled precision.
Considering the specific strengths, the blue light of shorter wavelength offers the best trade-off between enhanced resolution and the speed of the scans. Blue light 3d scanners’ accuracy and efficiency have rendered them very popular when highly accurate details need to be obtained in applications.
