HAQ-635 Red Laser Pointer
The HAQ-635 Red Laser Pointer operates at 635 nm, delivering a bright and highly visible red beam that can be clearly observed in mid-air under dark conditions — not just as a projected laser dot. Compared to traditional 650 nm red lasers, the 635 nm wavelength offers enhanced visibility due to improved eye sensitivity in this region of the spectrum. Its compact handheld design and AAA battery power supply make it suitable for professional, laboratory, educational, and presentation applications.
