Adjustable 405nm 350mW Blue-violet Laser Module for DIY Engraving/Laser Marking

Adjustable 405nm 350mW Blue-violet Laser Module for DIY Engraving/Laser Marking The 405nm 350mW blue-violet laser module features an adjustable focal length with a precise and user-friendly knob design, allowing flexible adaptation to different working distances based on actual needs for clear and stable light spot focusing. It adopts high-quality one-piece aluminum alloy housing, which undergoes professional anodization treatment—this not only significantly enhances insulation performance but also endows the product with excellent structural hardness, corrosion resistance, and wear resistance, making it suitable for complex working environments. Every module passes strict factory quality inspections, meeting dual standards for core performance and dimensional accuracy. With a standard size of 16×59.5mm, it offers strong installation compatibility. Additionally, we provide personalized customization services: we can adjust the voltage specifications and module dimensions according to your specific requirements to meet diverse application scenarios. Boasting concentrated energy and a pure light beam, this blue-violet laser module is suitable for DIY engraving, laser marking on metal/non-metal materials, thin material laser cutting, and other fields, serving as an excellent choice for professional production and creative practice.
