Laser Beam Expander - Tutorial and demonstration

www.dragonlasers.com Beam Expander Tutorial and Demonstration The broken light that point us has limit range that divergence instead of a beam, it cannot be controlled and they had no focus point. The Solution to these Problems The Beam Expander This is the beam expander from Dragon Lasers. Inside, it has four lenses. The protective cover of the back lens and the protective cover from the front lens. To use a beam expander to control divergence, range and focus is very simple. You just use it like this when it is connected to a laser. Now, that is a beam expander, a light point able typically has the divergence for beams spread between 1.2 mRad and 2 mRad. Now, we are rolling out the pointer, it has a difference of 1.5 mRad. This means that the beam will split up or expand 1.5 millimeter for every meter the beam travels. Now, the beam expander, you can reduce divergence in all laser pointers by a factor of 10. Now take for example, using a beam expander, you have a maximum of divergence of 33 millimeter and you have a minimum divergence of the light point of divergence divide it by 10 using the relative point as example that has a divergence of 1.5 mrad with the beam expander. It has a minimum divergence of 0.15 mRad so the beam expander. Next divergence 33 mRad minimum divergence 0.15 mRad. Now, by reducing the divergence or less by 10, you are making the range 10 times more. Now the beam expander, they can give away the point of focus anyway of 21.4 meters and affinity for practical terms, the focus point can be anywhere between 1.4 meters, and as far as you can see. The Beam Expander can be used with the following lasers Viper series Aurora series Spartan series [Demo] Spartan adapter from the Beam expander [Demo] Viper adapter for Beam Expander [Demo] Aurora adaptor for Laser Beam Expander [Demo] Beam divergence demonstration at 300 meters Spartan GW 200 mW Laser [Demo] Maximum divergence 33mRad [Demo] Minimum divergence 0.2mRad [Demo] Focus point at minimum Distance of 1.4 meters
