HAQ-520 Green Laser Pointer
The HAQ-520 Green Laser Pointer operates at 520 nm, delivering a highly visible green beam that is clearly distinguishable in mid-air under low-light conditions — not just as a projected laser dot. Thanks to the superior visibility of the 520 nm wavelength to the human eye, this laser pointer is ideal for professional presentations, laboratory work, and outdoor pointing applications.The HAQ-520 is FDA approved, ensuring compliance with relevant safety and regulatory standards.
