Thor H and for that matter Thor M2 is only available as either a 1.6W or a 3W ---- as you might very easily guess the vendor/marketer of Thor lasers also sells replacement lenses for them. $10 ---see Laser pointer Store link above your OP then go to the Laser Accessories page--Replacement Lens for Thor @$10 for a glass lens that will not melt like the early series with a plastic lens was prone to do
It does take the M9X0.5 housing like all the 6.3 mm glass lenses do. You can actually get either a multi-element lens or a single aspheric short focal length lens for less than $10 on eBay at several sites. Try looking at Techhood, Newgazer, Existotem or Laserland's sites. I believe they all carry these lenses, but the least expensive one will take a search as that changes from time to time.
You can buy M9x0.5M lenses from eBay as well as many other sites too. These are the most common lenses we use in pointers here. The question, however, is, is this the lens used in this particular pointer?
Thanks guys for all the help.I'm a little raw and new at this so bare with me it been a long time ago that Ive joined a fourm and ask questions and did this so will probably make a lot of mistake but Thank for the help. PS and buy the way laser pointer store has started to make thing right with problem I was having with them .So I apologise right now to everyone if it looked like I was bashing him that was not my intention at all
