HAQ-473 Blue Laser Pointer
The HAQ-473 Blue Laser Pointer operates at a precise 473 nm wavelength, one of the earliest true blue laser technologies developed for professional and scientific use. Known for its distinctive sky-blue emission, the HAQ-473 offers excellent spectral purity and stable Continuous Wave (CW) performance. Powered by a CR2 lithium battery and featuring push-button operation, the HAQ-473 combines portability, reliability, and optical precision in a professional-grade format.
