Poor focus on Odin 5W450 by C4Lasers

I just received a Odin 5000mW, 450nm pointer from C4Lasers. It has a focus ring, but the smallest 'spot' I can get at about 50 feet is a rectangle of about 1 inch by 5 inches. See pic.

I contacted their support@c4lasers.com, but they indicated that this is about the best to expect.
Is there a better focus lens available that I can use?

Thanks,
Bill

That is totally normal for any high powered laser due to the poor divergence offered by the multi-mode diodes they use

Yup totally normal, Sadly high power laser diodes without correction are often 'flashlights', I would even call that a good beam for that diode. They should be using already the best lens for divergence available (3 element). Also I regret to inform you that you way way overpaid. That laser costs about 100ish max in components and 30 ish max for that shitty standard host.

Just out of pure curiosity, where would I get that shitty standard WL host from? I've been meaning to make a 7W laser using it, but all the Alibaba listings I've seen are super pricey
 
Thanks for the info! I should have done more research before purchasing! I was 'sucked-in' by their spec that claimed the beam had a distance of 18.64 miles. But now, I'm ratioing my spot size measurements at 50 feet, and I estimate that the 'spot' at 18.64 miles will be about 800 feet wide. Their spec is very misleading!
Thanks!

It's just a cheap replica of the PL-E pro host from Jetlasers I think you could ask them for a host and they'd give you a good price although idk the exact price. Also, the cheap repilca hosts used to be on ebay.
 
I looked at (one time) diodes like they were made for us to use.. not so.
I doubt that the diode makers ever think about us and our uses.
(with possible exception the diodes used in aaa pen pointers.)


At best, I will guess that we buy less than 1% of the 'other' diodes made.
so that does not give us any 'buying power' or consideration. I cannot think of any device using laser diodes, where the focus is anyway near a small round dot at 50 feet.--MYB laser gun sights which are mostly red wavelengths.
I could be wrong.
 
My 'old' Wicked Laser, blue Artic, about 1.3W produces a very small spot at several hundred feet away. I was expecting the spot from this one to be similar.

Maybe someday, a very smart person will invent a laser diode that produces a round beam (instead of oval beams) directly from the chip, similar to the beam that comes out of my old Melles Griot HeNe glass tube.

Yea It's here and called: Any red dvd burner diode. Also, your WL artic has a better beam because it has a different diode (m140) Which is one of the best multimode divergence diodes available. King is the sharp 1w 405 with about half the divergence of the m140. Also, Single-mode diodes exist with a very low divergence(better than the sharp 405) oval-shaped or circular beam.

Nah they quoted me $70, even worse than Alibaba... guess I'll need to wait until I can either machine my own host or a cheaper option becomes available
 
Hi,
If possible see if the lens can be changed out for a G8 or a 3E lens to reduce the beam size by clipping the wings . You would need to see if the lens you are using has the threads of M9x0.5 .

Projector mod conversion - UHP lamp to laser... RGB? - help!

Hi! I'm new in this amazing forum. I'm working in a modification on a JVC RS46 projector, I've already done the ballast bypass for the UHP lamp and now trying to convert it to laser. I'm designing the lightpath using two OSRAM PLPM4L 450B blue laser arrays rated on 80 output watts each. One of...

check out some of these-^^^- will explain why you are not getting much help..sorry no fault on us or you.. I was told those crap hosts were made for WL at less than $7usd each/and buyers were treated very badly. lots of lies-- only wanted the money NOW--some waited a year..

anyone who was there understands. -- the fall-out was bad..
'we'(members) got hurt--as did LPF--and many others... lots of bad reports about injuries etc.
the press was all over this. They were sold to children-- anyone with CCard info.
and very few buyers had eye protection.
I'm sure there are many out there FS
any way not the lasers fault. good luck.
do a search....

Lol if only I were able to get one [host] at that pricing

I was of the impression that the beam pattern remaining tight over distance wasn't as much about lens focus as it was the density of the light? LEPs are in the area of 600 lumens but the light so dense that it makes the light appear to be as "bright" as the throwers that are producing tens of thousands of lumens, and remains extremely tight over distance. There's virtually zero diffusion of light over miles of projection. Yes, lens is certainly a factor. But there are handheld, even flashlights which don't diffuse like this. It seems to me that the issue is the quality of other parts, the diode even perhaps. Not so much the lens.
 
Hi folks,.I was born yesterday to this forum and I am really close to buying this laser after reading comments about Sanwu from all members here. Is this a good high quality laser that will last and not need any modifications of the box? It's the Sanwu Striker series 7.5w blue 445nm. About $580
Thanks for the help!

why are there a bunch of new people wanting high power blue lasers now
