A ballast resistor is necessary to run a bare laser tube.
(Lasers that are in a metal head will have one built in.)
It must be placed in series with the anode lead within 3″ of the tube.
68K ohm, 3 Watt metal oxide ballast resistor.
Recommended for HeNe laser tubes that operate on 6.5mA or less
- You cannot add "1mW 543nm Green HeNe Laser System" to the cart because the product is out of stock.
