Interesting way to get lens, Accutronitis. Thought about doing that myself. Thanks for sharing that it can be done. Be interesting to see what and where you go with them?
I found something !!!Hmmmm. convert into a beam expander?
Chormatic abberation is a real problem in lenses for photography indeed, and they spend a lot of cost to prevent/mitigate that.It's a real science to get a good quality image with the entire visible spectrum, you can see it with cheap rifle scopes where that's not what's important, however with photography you can take apart a zoom lens and find a dozen oddly shaped lenses that all balance out it's ability to take clear pictures under different conditions.
Wow. Looks like you hit on something there. A homemade BE very nice. There's something about building your own that makes thing special. Pics when your done. :gj:I found something !!!
Two of the lens I recovered can do something VERY COOL ! the first lens is a convexo concave lens and the other is a doublet lens.....
Together they can do something very cool ! first I thought i'll try putting the convexo concave lens here after my DTR G-2 lens and the "Milos" Triple Cylindrical Lens Fast Axis Correction focused to infinity....
So I temp taped it in place like this.....
And then I held the doublet lens in the beam path like so......
And the focal point was around a few inches with the doublet lens around a inch away from convexo concave lens and the beam was converging to a very small point BUT then I started moving the doublet lens away from the convexo concave lens and the fine focal point began to move away from the laser and when the doublet lens got to about the same distance away as shown in the picture above that fine point had shifted to the wall across the room and immediately started vigorously burning the wall and smoke started shooting out, The point was very bright and very small and very dangerous !
If I build them into a slip on lens apparatus that I can slip one tube with one lens away from the other and that apparatus could slip onto my fast axis correction mount I think it could make my Hammer 44 a real adjustable long range burner !!!
Good one :crackup: The same price of course for a whole lens.So $4000 is for half of the lenses? How much for the other half?:shhh:
