Red Cross Head, 650 Nm Cross Line Red Diode Module Cable

Works perfectly and seems to be well made

im using this as a side sight for my laser cutter to line things up a little better. Seems like the lines bow causing it to not be true. Im not sure why others are saying its dimm, i think its overly bright for my needs. I am trying to put a PWM dimmer inline to see if can lower the brightness some. The beam also shows about 2mm wide (if dimming causes the beam to narrow i will update). Either way im not overly happy about this but its probably not worth my time to return.

Great laser

This device worked great. Made my own 3 volt battery pack and a mount for my dimple machine. Works great!

This is pretty low power, nowhere near 5mW according to my laser power meter. It draws about 16mA at 3.5 to 5v. The cross is reasonably sharp but can only be seen at distance over 30cm with dim lighting or red glasses. It is out of focus closer than 8cm and there is no focus adjustment

I bought this for my 24x36 CO2 laser and it does give me a faint red crosshair pointer. Just wish it was brighter.
