Dear all,
i am looking 4 a collimator for my 808 nm 1000 mW 5,6 mm can diode.
Any suggestion where to buy it ? I need a good quality glass collimator. I already have the Aixiz module but it's for the 3 mm diodes !Any suggestion would be fine !!
Thank you all !!!

If you can't buy a ready made one you may need to make one yourself. Here you'll find lenses for near IR

ready made what?
5.6mm is a very standard diode size

first before you purchase, make certain the the lenses can handle the heat that will be generated. You may need something like calcium flouride lenses. you will certainly if you want maximum light transmission want to be certain the lenses are AR coated like these which by the way may be suitable

If you want best performance any old lens won't do. You probably spent good money for that laser right ?

The Meredith Module lenses are AR coated, and how can the heat damage a glass lens?

it can abalate the surface making little dots and defects where the beam is therefore ruining your beam by changing the lens focal range on that spot...

Well guys, i am not so aware of what the heat can do to a glass lens. Edmund has a very good catalogue of lenses but i am in trouble for what to order.
The laser i want to build must be efficient and i want to transfer as best energy as i can to the focal point. I will look forward to your kind suggestions to get the right product.
The diode comes from ebay, i already heve tested it and it's not so expensive.
Thank you all and have a nice day!

Are you positive it is a 5.6mm 1W diode? I thought those came in 9mm cans most of the time. Maybe you're confusing 9mm can with 5.6mm and 5.6mm with 3mm(?) :-/ (Just throwing that out there as a possibility. :p)

The heat generated by the diode is probably more of a worry than the heat generated by the actual laser beam.Good heatsinking should fix this though.

Also watch out for the proper AR coating.Some lenses (for example) are AR coated for green and pass like 3% of IR.

Well I am pretty sure it's a 5,6 mm can 1000 mW 808 nm. and it's damn powerful!!!!!
Thank you 4 the suggestions !!!
