It’s a 785nm semiconductor laser, it’s support CW and modulation, the output power is tunable. The laser output power can be adjusted by turning the silver button. The working voltage is 90~240V, which is suitable for most countries and regions in the world. 785nm laser is near invisible laser. The laser light is weak, but the energy is strong. And the packaging of the products has been fully shockproof. Let’s check it now.
