Quarton Laser Module VLM 520 28 LPT Green LINE Generator (ECONOMICAL Laser)

ECONOMICAL GREEN LINE LASER FOR SHORT-RANGE USE: The VLM-520-28 LPT is an economical green line laser module designed for short-distance projection. Its direct green laser diode delivers a clear 510~530 nm line optimized for 0.3~1.8 m working distance, ideal for 3D scanners and basic alignment tasks. INDUSTRIAL-GRADE DESIGN: Although positioned as a cost-saving model, this module integrates essential industrial features: an aspherical plastic lens, plastic wave lens, APC driver circuit, and brass housing. Suitable for consumer-grade devices that require stable line projection without high system cost. ENGINEERED PERFORMANCE FOR EASY INTEGRATION: Specifications include: Class 1 output (60° emitting angle, and compact Ø9 × 26 mm size. The APC control keeps output stable and helps protect against current surges, allowing smooth integration into OEM equipment. OPTIMIZED FOR INDOOR STABLE TEMPERATURE ENVIRONMENTS: Built with plastic optics to reduce cost and weight, this module performs best in standard indoor room-temperature settings (+15°C ~ +30°C). Not recommended for high-heat, low-temperature, or outdoor extreme environments. BUILT FOR LINE-PROJECTION APPLICATIONS: Designed for consumer-grade 3D scanners, barcode readers, leveling tools, alignment systems, and positioning or measuring devices. Also applicable in light-duty tasks across wood processing, metal processing, textiles, food equipment, automotive setups, and scientific devices. Notice: Our laser modules are NOT laser pens and are NOT intended for general commercial or consumer use like standard laser pointer. They feature NO built-in switch or battery compartment and must be operated with an external power supply or battery holder.
