Mini 650nm 100mW Red Dot Laser Diode Module for Laser Rangefinder

This Mini 650nm 100mW Red Dot Laser Diode Module is a high-performance core component tailored for laser rangefinders and positioning systems, integrating ultra-compact design, 650nm red laser’s high visibility, and 100mW high-power output. It emits a sharp, stable red dot to serve as the reference light source for distance measurement and spatial positioning, enabling accurate data acquisition in outdoor, industrial, and consumer scenarios—becoming an ideal choice for handheld rangefinders, construction positioning, and precision measurement equipment.

Core Technical Advantages for Rangefinder & Positioning

- Miniaturized Design for Compact Devices: With a housing diameter ≤8mm and length ≤11.5mm, it fits into the slim form factor of handheld laser rangefinders and small-sized positioning sensors. The lightweight (≤10g) structure avoids affecting device balance, supporting portable or embedded deployment in space-constrained equipment.

- 650nm Red Laser High-Visibility Optimization: The 650nm wavelength boasts strong naked-eye visibility and high contrast against most backgrounds (metal, concrete, vegetation). Even in outdoor daylight, the bright red dot remains clear, ensuring laser rangefinders capture target points accurately and positioning systems achieve precise reference alignment.

- 100mW High Power for Long-Range Performance: Delivers stable CW output with an effective range up to 200m. The high power ensures the red dot maintains sharpness at long distances, enabling laser rangefinders to measure distances accurately and positioning systems to cover large-area reference points without signal attenuation.

- Precision Dot & Narrow Divergence: Features a small red dot (size ≤10mm@10m, ≤50mm@50m) . The focused beam minimizes target point deviation, ensuring positioning accuracy for industrial assembly, construction marking, and precision measurement tasks.
