Ok, I am not usually one to post a lot of reviews... Mostly because I only have 3 lasers at the moment, blue heres my review of a 100mW Blue Ray pointer from Jake21.

Starting off, delivery was incredibly quick, I have been saying for some time that I am going on holiday on Tuesday and I will need it delivered before I go. Sure enough I woke up today and there it was at my door, that was sent from America to England in just under seven days! Packing was good as well, a nice padded envelope covered in possibly a mile of sticky tape.

It seamed all ok and passed through customs with no trouble at all, although from what I can only assume, there is a 5mW 532nm sticker on the laser which would have helped it pass through customs if it was opened.


No real issue with that, anything that helps is good.

The laser came with a few little extras that I was not expecting, especially from my past experiences with DIY lasers. It came with a nice, almost white, fabric box. I am not actually sure where this box came from, it looks like it was used for another laser in the past going by the fact the laser does not fit properly in length and it is a little tight to fit it in there. I also got a nice glow tile, I have yet to test this properly though as it is rather hard to see in day light.


The laser is powered by, what look like, AAA batteries. They work well enough but I have tried using the same AAA Duracell batteries I use in my 75mW Viper. I was surprised to find that AAA Duracells did not work in this laser, I will try again with new ones but for some strange reason they do not work and they work in my greenie.


Just as a styling comparison, I placed it alongside my DL Viper 75, obviously it isn't the best looking in the world but I don't think it looks that bad. The Blue Ray is inside an all metal housing which does help with cooling as I have used the laser for 5 mins now and have started to feel the tip getting warmer.


Ok, onto the most important now, the laser itself. Now, I must admit this is my first blue ray so I cannot really tell if it is actually 100mW from looking at it and I do not have a power meter to test it on. Although compared to my 75mW viper it does seam rather bright.

I have only noticed two downsides to this, the first being the beam colimination is terrible from two meters away the dot is already 1.5cm big, from what I can see the optics used in this laser are adjustable so I may have a play around with this. The second downside is from time to time I get a 'double dot' I had this with my Viper a while back when the batteries were really low and it was mode hopping, for some strange reason if I turn the laser off and point it somewhere else at another angle it does fix itself. Perhaps the diode is loose inside? I have also noticed that sometimes when it does this, the dot turns into a rather dim blob, but as said if I move it about a bit then it does sort itself out.

Heres a shot of the dot side by side to my Viper, as you can see the blue ray has turned into a nasty looking blob. (note: the Viper was on used batteries in this shot)


...and a shot of the beam when it has fixed itself.


The actual beam itself is, almost, visible in daylight depending on which angle you look at it. I have yet to test it in the dark yet but I can only assume the beam will be visible in the dark.


Overall, this laser is not bad at all. I have had experiences in the past with lasers not even working when they turned up at my door. Obviously there are a few bad points about this laser but lets face it, it is a DIY laser so I wasn't expecting professional quality or anything. The box and glow tile are a nice little extra, and I am sure I will be spending the next few weeks playing around with it.

your rite when u move the laser around when it turns into a weard dot it fixes its self ? i thought it might of been from the axiz lens might be loose not the diode i dont think because i pressed fitted that in with a vice. and the batteries thats needed for that laser are 10440 batteries found at dx if u need help with the laser pm me ill be glad to help and thanks for the review

The dot "changing" when you move the laser sounds like the window in the diode is broken. This means that there is a loose piece of glass moving around inside the diode housing. When you move the laser (especially turning it over), the piece of glass some times block the light, sometimes deflect the light, and/or sometimes split the light coming out of the diode. Remove the lens and look at the the opening of the diode. You should be able to see a smooth piece of glass covering the opening. If not, you have a problem (or Jake does). If you turn the laser slowly while looking at the diode opening, you may be able to see the pieces of the shattered window moving around inside the diode.

If you are VERY lucky it is just one big shard and you can get it to lie against the side of the opening. If you can do that, then you MAY be able to "glue" it in place, out of the way of the laser light. IF those two conditions are present, you would have to use cyanoacrylate and a very small probe. IF you can get it to lie in a fortunate position you MIGHT be able to place a small amount of the CA on the point where the glass touches the housing. I need a set of ten power magnifiers to do this work as well. The opening and the glass shard(s) are very small.

If you can't get it to lie in a fortunate position, it is too small, or there is more than one piece in there, you (or Jake) are screwed. The piece of glass will continue to move around until it eventually strikes the fine wires that connect the crystal to the case and the diode will die.

Sorry to be the bearer of bad news.

Peace,

Thats a bit unnerving...

I have sorted out the colimination, sort of, by tightening the lens and it now has a very bright dot and goes about 5 meters before the dot gets bigger than 1.5cm.

I tried holding the power button and slowly rotating the pointer, I noticed that half a turn it has a double beam effect and the other half of the turn it is perfect. I will take a look though and see what I can find, I am not sure about blue rays but greenies do this on low powered batteries, perhaps it just needs a good charge?

Edit: hate to say this but I just took a look and it looks like there is a crack in it. Although I am not 100% sure because it is so tiny.

Like I said, I need a 10-power loop to see it well. Your green laser is "mod hopping". The actual beam from the crystal set is changing with voltage, current, and/or temperature changes. Diode lasers do not mod hop. Diode lasers are constructed differently. 405nm blu-ray lasers are diode lasers. Your blu-ray is NOT mod hopping.

The results of your "experiment" in turning the laser with it shining and observing the change in the beam, confirms my suspicion. The window is broken.

Peace,
dave

[highlight]**EDIT**[/highlight] The collimation of the 405nm beam is different from the collimation of the 532nm beam. We can get that explained after you have a good, consistent beam to collimate.

I have spoke to Jake21 and getting it sorted out.

I would be more annoyed if it was from a professional company but as I said in my review, its a DIY laser so it wont be perfect.

Why do you need to use a middle man when doing business with Jake? The red laser I got from him was defective and he gave me a refund without any trouble...

I had something similar happen with one of my blu-rays, I thought the window was cracked but there was just a piece of hair or something stringy on the window. I removed it and the dot was mostly normal aside from some cloudy light around the dot. Any suggestions for window washing.

sounds like daguin just has a bone to pick with me ;)

Not you personally, just your business practices.

You view these comments as attacks on you because you lack the maturity to understand. Everything I've said and recommended is to help make you a better builder and businessman. You appear to be in this for a "quick buck" rather than to learn about lasers or to supply quality products to your customers. In the rest of the world, I don't give a shit. In this list, I accept a level of husbandry by accepting membership here.

Peace,

You don't need to do anything. It is just my recommendation. You should have never gotten into the situation that would require the immediate replacement of a laser. These are not mass produced and then shipped blindly to resellers. These are not mass shipped without testing like DX. Each laser he ships should be completely tested by him. Quick, painless refunds are important with someone like DX. They order a laser from the supplier and ship it out again without ever opening the wrapping. Jake makes the lasers one at a time. There should be no "quality control" issues when the laser is delivered. You shouldn't need a painless refund. The laser should never have shipped.

Agreed. In our never ending search to be the cheapest consumers possible (face it, here on LPF our laser purchases are to the point of buying your potential fiance a plastic engagement ring off of DX to propose with) we have gotten far too lax with quality standards. As far as I'm concerned if a company says they'll do something, they should make good on it.

If Nova tells me I'm buying a 150mW laser - I expect 150mW. When we start dealing with companies like DX as well as many of the DIY sources for lasers, that guarantee no longer stands up. It doesn't mean you're getting a bad deal, but we should still criticize. I'd rather get a good deal from an honest company than a good deal from one with questionable business practices, and its not fair for others to have to compete with them either. I have my own share of problems and I've botched plenty an order myself, but I daresay I still look pretty damn good compared to some of the stories I see weekly around LPF. I don't know the situation with Jake21, so what I'm saying doesn't necessarily pertain to his deals, but when we deal with people like BlueFusion who are obviously trouble from day 1, and then we still have to deal with people defending him as he rips others off.... Frankly, its very frustrating to me.

I've complained many a time about one place or another engaging in fraudulent business practices to the point where I feel like some paranoid conspiracy theorist with my tinfoil hat. In retrospect, I'd have to guess I was right at least 95% of the time though, and in retrospect, I've also been criticized for trying to call these places out a majority of the time. Yes, I get it we want cheap lasers at "too good to be true" prices - I'd like that too. What are you willing to sacrifice in such a pursuit though? So far I've seen much of the forum lose nearly all sense of business ethics as well as a fair share of dignity. Perhaps we can start by demanding a higher level of ethics and quality from any people we offer our hard-earned money to? Or maybe we should just continue financially supporting those who will stop at nothing for a buck...

till next time, [/rant]
