Focusable 660nm 50mW Red Circular Beam Laser Module

The Focusable 660nm 50mW Red Circular Beam Laser Module—a high-precision optical component engineered for versatile positioning, calibration, and aiming tasks across industrial, scientific, and consumer equipment. Featuring a uniform circular ring beam, stepless focus adjustment, and stable low-power output, this module delivers clear, distortion-free optical guidance for scenarios requiring pinpoint accuracy and consistent spatial reference.

Core Advantages

660nm Red Circular Beam: Pinpoint Precision & High Visibility

• 660nm (±5nm tolerance) red light offers excellent naked-eye visibility and low ambient light interference, standing out sharply against metal, plastic, and natural surfaces—ideal for both indoor calibration and outdoor aiming applications.
• Standard Gaussian circular beam with high uniformity; focusable spot size ranges from 1mm (fine focus, 0.5m distance) to 10mm (broad focus, 10m distance), ensuring pinpoint targeting for micro-components and a clear reference for large equipment alignment.

Stepless Focus Adjustment: Adaptive to Diverse Distance Needs

• Built-in precision focus ring with a focal distance range of 0.3m–10m, supporting short-range tasks (e.g., SMT component positioning, microscope calibration) and long-range applications (e.g., industrial machinery alignment, surveying reference) without additional optics.
• Tool-free focus tuning: rotate the focus ring to shrink or expand the spot size, adapting to different target sizes and working distances—one module fits multiple use cases.

Stable Low-Power Output: Safety & Reliability Balanced

• 50mW CW output with lower power fluctuation over 24 hours (25°C), ensuring consistent beam brightness and avoiding drift-induced errors in precision alignment tasks.
• Class 3R laser safety compliance (IEC 60825-1): safe for short-term human exposure at standard working distances, eliminating the need for bulky protective gear in workshops, labs, or field operations.
• Ultra-low power consumption with 3V–5V DC wide-voltage input, compatible with battery-powered portable devices.

Compact Durable Design: Seamless Integration

• Miniaturized anodized aluminum housing (16*66mm), fitting effortlessly into optical rigs, industrial alignment tools, handheld aiming devices, and consumer electronics.
• Optional features include a 360-degree rotating universal bracket and a 110V/220V regulated power adapter.

Key Applications

• Industrial Calibration & Aiming: Machine tool spindle positioning, conveyor belt alignment, SMT pick-and-place machine component targeting, and robotic arm path calibration.
• Optical Instrument Debugging: Telescope, microscope, and laser rangefinder optical axis alignment; camera lens focus calibration and distortion correction.
• Consumer & Portable Devices: Aiming scope accessories, DIY positioning tools, drone target marking systems, and laser level auxiliary reference sources.
• Scientific Research: Optical experiment spatial reference, surface topography measurement auxiliary, and lab equipment alignment calibration.
• Medical Device Tuning: Surgical instrument positioning, medical imaging equipment calibration, and dental tool alignment (safe Class 3R operation for clinical environments).
