Default Re: Does anyone have any experience with meierlight?

Ok, here's the deal...I negotiated, if you will, a $850 analogue unit that he (Fang) guarantees will come in between 1700-1800mw, this includes shipping. I mentioned to Fang there was some interest in putting together a group buy but I am not sure he understands the concept. Anyways, he says to ask for him and he will give a good deal like above for anyone who asks. I just sent the money through Paypal so I should be getting it soon. I will post a link here for a full review. Fortunately these guys accept PayPal which makes it a buyers advantage...if it doesn't perform at least I have some protection.

I contacted CNI before o bought this one and the best they could do was 1500mw for $800 PLUS $110 shipping and $7 insurance. That's not a bad deal, $917 for a CNI 1500mw laser but I am going for the 1800mw at $850. Since all their lasers come in over spec I am hoping, by chance, mine will come in even higher than 1800mw...wouldn't it be great if we broke the 2w mark for less than a grand! Doubt that will happen but you never know...these guys seem to be real interested in getting a good name for themselves.

OK, order placed and paid for...will arrive in 3-4 days....this price included DHL shipping! I inquired again about a possible group buy but I really think he doesn't understand the concept. Anyways. his response was he would sell a 1200-1500mw for $790 shipped. I think for the extra $60 you might as well go for 1700-1800mw.

i should have this by the weekend and I will get back with some data then.

This is great! Honestly the prices are so low already that I don't know how much lower they could even go for a group buy so it's no big deal if he doesn't quite get it. $850 for a 1,700-1,800mW 532 with DHL shipping is (excuse my language) fucking awesome. I think I might have to place my order sooner than originally planned. I'm looking forward to you getting yours. Keep us posted.

Got a phone call from DHL this morning, they confirmed the arrival of the laser in OKC today and that it will be deliverd to me today between noon and five this evening. They were spot on the delivery time, 3-4 days is what Fang said and today is day four. I will link a full review here when I receive it and have run some LPM numbers for everyone.
2-7 hours and it will be here....I can't wait!

Default Re: Does anyone have any experience with meierlight?

I'm really looking forward to you getting your laser. 3-4 days for a laser from china is also really awesome. LoL I'm looking forward to this as if I was getting a laser. But if all goes well with yours I am 100% going to buy the same one.

Meierlight seems like a real diamond in the rough IMO. 1,700-1,800mW of 532 for $850 is unheard of. Despite the fact that several people here have purchased lasers from them it seems like nobody ever mentions them when talking about sources for lab lasers.

Default Re: Does anyone have any experience with meierlight?

Ok, it just arrived...there's a pair of wires coming out of the back of the PSU that says analogue 0-5VDC, red and black. There is a note inside the box that says to connect 5v to these wires otherwise the laser is off...

Can someone explain to me exactly what this is and how I should best implement it? Also the note says with 5vdc connected the lasers at max output...does this mean at a lower voltage the output is lower...is this how the output is regulated, by varying the voltage to this "trigger"?

I am leary to connect 5vdc to these wires until I have some input, I don't want to screw anything up. I plugged the unit in and connected everything except the 5vdc and the PSU powers up and the fan on the laser head powers up as well. No laser output though, which is to be expected I guess...until I connect 5vdc to the analogue trigger.

Someone please give me some advice here, the instructions are written in the standard English translated from a chinaman so I am just concerned the translation may be off a little...

Otherwise, everything looks good...no dents or dings from shipping.

It's a solid liking unit but again, I have little experience with these lasers.

Thanks,
Jeff

Analog modulation inputs use a signal to vary the output power of the laser, from 0-5V. Lower voltage = lower output. Hook a 5V supply to that wire for max output.

Default Re: Does anyone have any experience with meierlight?

I hooked up three AAA batteries in series for 4.5v and got it running. I need to make a variable power source for 0-5vdc...anybody know of a good schematic for a simple Analogue trigger source like this? I was thinking of using an LM317 or similar with a pot...my only concern would be going over the max 5vdc...anyone know if it would damage the PSU if you went a little higher than 5vdc? I am confident I can make a variable source that will go ner 5vdc but not too confident I can make it to where it doesn't go over 5vdc...a good schematic for something like this would be great if someone knows of one.

At 4.5vdc all I can say so far is......dang! It's bright! Just shot it out of the fourth floor of the hospital where my call room is....wow....the security guard at the college saw it across the street(didn't point it anywhere but up, not at anything) and he shined his spotlight back at me! I was just shooting it over and way above the campus....won't be doing that again...fortunately I have a 5mw green pointer in my bag of anyone comes snooping around..

So far I am impressed..the beam at the aperture appear to be around 2mm but I haven't measured it. It is brilliant, completely blows away my 380mw handheld, there's really no comparison.

I am on call tonight so when I get home in the morning I will measure the output at 4.5vdc immediately and will get to work on a 5v supply also. I hope to have some real data for y'all in the next 24hrs.

Cheers!

So far this sounds awesome. Im looking forward to when you get some output tests. I am also going to need to make some kind of variable power source for the 5v when I buy mine so I'll also try to find a suitable solution for it. If you can do a couple of beam shots at some point that would be awesome. errrrr I can't wait until I can get mine. I just need to be disciplined though and wait until my wallet has recovered from the holidays shouldn't be more than a month maybe 3 weeks.

One of the things Im curious about is wether it's IR filtered or not. I would assume it is but It could very well be unfiltered. If you have an IR filter try LPMing it while filtering the beam and based on the change in output we can tell if it is. Congrats on owning a (hopefully) 1,700mW 532nm.

Default Re: Does anyone have any experience with meierlight?

I bought a LM317 based variable power module on eBay for $15. It's DIY and will range from 1.25v to 35v depending on the input. I have a 6.5v AC transformer to connect to it so with the diode drop and the rectification gain I should get about a 7.5v dc max. I have yet to find out if it's ok to drive more than 5v into the trigger. If not I will solder a stop on the pot at 5v output so it won't turn past 5v. If you are interested in this kit let me know And i will find the eBay listing for you and post it here.
Cheers!
