Hi,
Really thought I dont have to do this but You should know this too.
Bought a laser from Tarm two years ago. Offer and Invoice had clearly staited 1000mw green.
As I did not have the meter at this time I could not measure it.
As they gave 1 year warranty I did not open it.
Bought a powermeter and discovered that it did only 500mw.
Asked them to send me instructions for re-algining the laser.
They sent a picture and said that it normal that laser loses half its power after 200h work within 1 year.
Took a cover of my laser and green modul had 600mw on it.
Writed to Tarm and got a letter back. They asked a serial nr of the module. Send it to them with a picture and then they just said that the warranty is over and they could change it but I have to pay for it.
Afrer I told them that this is not warranty case I havent got any response about 6 months now.
This is the picture that they sent me 1 year after I bought it. This is picture of my laser that clearly shows that they sold me 600mw green.
Priit
