Focusable 650nm 5mW Red Straight Line Laser Module

The Focusable 650nm 5mW Red Straight Line Laser Module—a compact, high-precision optical component engineered for alignment, calibration, and positioning tasks across industrial, DIY, and scientific applications. Featuring a ultra-straight, uniform line beam, stepless focus adjustment, and eye-safe low-power output, this module delivers reliable optical guidance for scenarios requiring linear reference and precise spatial alignment.

Core Advantages

650nm Red Straight Line Beam: High Uniformity & Visibility

• 650nm (±5nm tolerance) red light boasts excellent naked-eye visibility and low ambient light interference, standing out clearly against metal, plastic, wood, and glass surfaces—ideal for both indoor calibration and outdoor alignment tasks.

• Standard straight line beam with high linear uniformity; focusable line width ranges from 1mm (fine focus, 0.5m distance) to 10mm (broad focus, 10m distance). The beam maintains a straight, non-distorted profile across the entire working range, eliminating alignment errors caused by beam bending or fading.

Stepless Focus Adjustment: Adaptive to Diverse Distance Needs

• Built-in precision focus ring with a focal distance range of 0.5m–10m, enabling tool-free tuning of line width for different application scenarios:

• Broad focus (1mm line width): For wide-area alignment tasks like conveyor belt leveling, cabinet installation reference, and laser level auxiliary line projection.

• No additional optical accessories required—rotate the focus ring to achieve the desired line width in seconds.

Eye-Safe Low-Power Output: Stable & User-Friendly

• 5mW CW output with ≤±1% power fluctuation over 24 hours (25°C), ensuring consistent line brightness and avoiding drift-induced alignment errors during long-duration operation.

• Class 2 laser safety compliance (IEC 60825-1): The low power output poses no risk of permanent eye damage, eliminating the need for protective goggles in workshop, lab, or home DIY environments.

• Ultra-low power consumption with 3V–5V DC wide-voltage input, compatible with battery-powered portable devices (e.g., handheld alignment tools) and extending runtime by 30% compared to higher-power alternatives.

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).
