450nm 5mW Blue Dot Laser Module for Laser Positioning

450nm 5mW Blue Dot Laser Module for Laser Positioning This 450nm blue dot laser module delivers reliable performance in a tiny, durable package—ideal for precision laser positioning across industrial, hobbyist, and DIY applications. This dot laser module operates at 3.7V DC (compatible with common power sources like USB or battery packs) and outputs a stable 5mW blue laser beam with exceptional focus: at 10 meters, the dot remains less than 12mm in diameter—critical for tasks requiring consistent, tight alignment. Crafted with a robust brass housing (6.5 ×10.5mm), this laser module balances portability and durability, fitting seamlessly into compact devices or tight assembly spaces. Its static, surge, and reverse polarity protection safeguards internal components, while the collimated optical lens ensures a crisp, non-divergent dot even at extended distances.   Core Specification : Wavelength 450nm Output Power 5mW Working Voltage 3.7V Beam Mode Dot beam Beam Size ≤12mm @10M Housing Size 6.5*10.5mm (Customizable) Lifespan  10,000 hours Product Display :     Our Services : We have over 15 years of experience with Lasers.
