This system will require soldering and basic skills of electronics in order to make it run, everything is included necessary except for a common power cord you'll need to plug in for household current. I will also include a color brake down of wiring of this SLM laser. This purchase includes is one B W controller with pigtails, JDSu laser head, 5 V DC Power supply, an extra 10 K thermistor (these petite wires are easy to break off during soldering!) and a brass pinhole to clean up the beam, International shipping no problem! This is a super laser to use for DCG HOLOGRAPHY!
