If you want a 405 to play with without spending a bunch of money, look on Ebay and Amazon. The 5mw ones are almost always pretty far over spec. The $8 ones I got off Amazon were close to 20mw, and for $8, its a good buy for a first 405. They are still impressive, and fun.

Yep, everyday ole $3 safety glasses. Get clear ones though, not any of the tinted ones. Yes, they are refillable. Its more expensive than buying a new tube, WAY more expensive. Unless you had a really nice expensive tube. not sure if a refiller would do that tube anyway. Best to hook it...

Its not the tighter beam that makes it show up purple. A 405nm laser is a VIOLET laser, verging on ULTRA VIOLET, regardless if the beam is 1mm, or 100ft ,which has the ability to fluoresce certain materials. The fluorescence in certain white objects make it appear blue. If you want a blue...

Actually, I would bet the percentage to scamming buyers, and scamming sellers is about 50/50. I got hit by a guy once, that within the 60 seconds that PayPal allowed him to file a dispute he did so. WAY before the item could possibly arrive in Croatia, even if I sent it overnight. I think he...

A pair of normal decent quality safety goggles is typically good enough for CO2. They actually almost completely block CO2 emission wavelengths. A prolonged direct exposure would melt through them however. You can power it with a neon sign transformer , however it will have diminished life...

You really cant compare that laser to the one in this thread. Its a 445nm laser as opposed to the 405nm in this thread. Very different beasts!! Is it better? Yes, if you want true blue, and a VERY visible beam, and much more power. No, if you want a VIOLET 405nm laser like in this thread.

The first one is definitely a CO2, about the 30-40W range as suggested. The second one, with the green trumpets, may not be a CO2. However, it could be!!

Most of the time, the person you would talk to, knows less about the product than you do. What they are telling you, they are reading right off the product listing, anything more than that is usually just BS.

Laserbee, your situation is better than mine. I have over $500 in my account that I cannot access because Paypal wants "Supplier Documentation" and "Proof of Purchase" on items that I made MYSELF on my OWN machines with my OWN material on my OWN time. I supplied them with all the info I could...

I know this is a kinda old thread, but you are absolutely right!!! They are selling the same lasers everybody else does, at higher prices to make them appear better. It called "False Economy" Also, just because you bought a cert with your laser, doesnt mean that the laser they sent you is the...

I just posted THIS if your still looking.

I have a 40W sealed CO2 tube (Chinese), a Universal Voltronics power supply that powers this tube very nicely (its actually for a much larger tube), 2 mirror mounts, 2 NEW silicon total reflector mirrors , and one NEW GaAs focusing lens. The only has a few hours on it. I had a cutter and this...

Hey RHD, any update on the crystal set?

Yes, indeed!!!! In fact, I did!!! Im sure Survival can confirm that. Anyway, this thread was in no way to implicate Survival for any wrong doing. It was merely to indicate that some of the anomalous output seen on 445nm diodes may be from a bad lens. However, indicating where the component...

Absolutely, not blaming anyone for anything. He didnt make the lens.

I just got a 445nm AR coated 3 element lens from Survival Laser. Got my laser all assembled and noticed some non-typical anomalies in the output. It appeared to be a very dirty lens, however upon inspection it was spotless. The output actually appears somewhat if its going through a...

Olike (as well as some others) sell a decent "lab style" 1W 445nm module. It may be your best bet for the display project. I may ultimately be cheaper in the long run to just buy ready made modules for this type of project. O-like also sells the glass cylindrical lenses for generating lines...

That laser style is sold by many, under many different models/brands. I dont think the real manufacturer is known for sure. I can guarantee its probably less than 100mw.

If what you bought is just a diode, it will not be green. Do you mean a green module? Post a link to what you bought.

I doubt the diode will screw out like in the pic. Most diodes are pressed in. The only modules I have seen with the threaded diode retainer is the old style NewWish modules. It will have to be pressed out, and the new one pressed in.
