Hi, This is my first post on this forum, just joined. I recently purched the S3 Spyder III Arctic portable 1W laser from wickedlasers. I bought it to try and make some cool photographs and photoshop them. After testing the device (glad I bought safety goggles with it) I was wondering how hot the laserdot actually gets. Short of buying an expensive thermometer is there any way to guestimate this? I've tried to set fire to a match (used one) and a candle wick that also has burned before. I'm not sure but I guess a catalyst like an actual flame is necessary to ignite those materials no matter how hot you get them to be. Does anyone have an easy way to determine what temperatures could be reached with this laser? It operates on an average of 900mW and at a wavelenght of 445nm. I'm not versed at all in physics, save from the little I remember from high school so I'm sorry if it's a stupid question.
