Lasers RF And Glass Tubes
The joints are best sealed with a special silicone compound to reduce the chance of high voltage breakdowns. Glass tubes are water cooled, using a simple system with a small pump and reservoir in which the water is allowed to cool before re-entering the laser. For machines used intensively, say several hours each day, a water chiller will be needed,ours have a refrigerant and radiator to chill the water resevoir .
We now can offer a long life selection of tubes with 80watt,100watt,150watt with a lifespan of 10,000 hours this is a first in the U.K with a competitive price of less than £1500.00 to upgrade with tube and power supply.
We offer two chiller systems a high capacity chiller for 80watt plus machines at £600.00 and a more afordable chiller with lower cooling capacity at £265.00. Cheaper coolers may just blow air over a radiator carrying the cooling water. It will wreck the laser tube if it is run it without cooling water or if the water is too hot and we provide interlocks to stop you turning it on without the water pump working. Some ingenious operators still manage to try…. The choice between the two main types of laser is one you must make, but be aware of the substantial difference in replacement costs. They both need positioning carefully so the invisible beam hits the centre of the mirrors in the ‘flying optics’ system delivering it to the focussing lens, near the material being engraved. This alignment needs practice, so we will be happy to fit new tubes when needed, to be on the safe side. Of course we provide instructions, in the form of a DVD, to show you how to align the system.
