Economical Red Line Laser Module 650 nm, Class 1, 2.6~6 VDC, >60° Fan Angle, 0.3~1.8m Working Distance, VLM-650-28 LPT - Industrial Alignment Laser for Automation & Machine Vision

• ECONOMICAL RED LINE LASER FOR SHORT-RANGE USE: The VLM-650-28 LPT is an economical red line laser module designed for short-distance projection. Its red laser diode delivers a clear 645~665 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 (<0.39 mW), 2.6~6 VDC, >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.

The VLM-650-28 LPT is a compact and cost-efficient 650 nm red line laser module designed for applications requiring short-range, high-visibility line projection. Although positioned as an economical series, it incorporates multiple industrial-grade elements, including an APC-controlled driver circuit, integrated wave lens, collimating lens, and a durable brass housing for improved heat transfer and vibration resistance. Its aspherical plastic lens and plastic wave lens help generate a tight, clean laser line at a distance of around 1 meter, making it ideal for consumer-grade 3D scanners, barcode reading, alignment, leveling, and targeting devices. The module provides an emitting angle greater than 60° and is optimized for short-range tasks from 0.3 to 1.8 meters. With a rated 10,000-hour MTTF (25°C) laser diode life and a 2.6~6 VDC operating range, the VLM-650-28 LPT delivers consistent performance within typical indoor temperatures (+15°C to +30°C). It is not intended for outdoor extreme temperatures or high-stress thermal environments. Suitable for light-industrial and consumer applications including wood, metal, stone, textile, food processing, automotive systems, and basic scientific or medical equipment.
