In fields including precision processing, industrial sensing, medical aesthetics and scientific research experiments, semiconductor laser modules have become core light source components for modern smart equipment and automated production lines, with core advantages of high stability, high photoelectric conversion efficiency, compact structure and easy integration.
Since its invention, laser (Light Amplification by Stimulated Emission of Radiation) has become a cornerstone of modern technology and medicine. However, few realize that the wavelength of a laser—its color and the invisible "light" it emits—is crucial in determining its applications. From precise ophthalmic surgery to deep-space communications, from micro-machining to defense technology, the choice of wavelength is like giving a laser a unique "identity code." This article will unlock the mysteries of different laser wavelengths and explore how they are profoundly changing our lives.
Why 405nm?
· 405nm near-UV wavelength matches the maximum absorption peak of all mainstream UV photopolymer resins (including elastic resins for 3D printed shoes), enabling efficient photopolymerization/curing.
· Higher photon energy than ordinary LED, deeper curing depth, wider adaptability to high-viscosity, high-filler industrial resins.
DLP (Digital Light Processing) is a vat photopolymerization resin 3D printing technology.
