Meierlight is simply a reseller of CNI and DHOM products, their TTL 1W green is a DHOM, while their analog 1W green is CNI.

A higher power may not only require a larger crystal set, the amount of resonant medium used may also be greater. The end result may mean that a fat beam is produced, and to meet the output beam diameter specification, a higher-power final objective lens may be used. The job of this lens is to...

Yep, they get HOT. My pair of amps came with oversized heatsinks, even then, they need forced-air cooling if they're to remain cool to the touch. This is with the included PT-ITRUST card, running at around 12kpps. Anything faster, and I'd assume air cooling would be required in order to...

Oh, sh#t. I didn't realise it had gone missing, last I checked, it was there. It was a sticky, and the link I've followed doesn't work either. Thanks for bringing it up, I've been so tied up I wouldn't have noticed either. I do have a backup (text only), so I'll try and get it online again...

The amount of power you lose depends on the scan angle. As I was saying earlier, here's an exaggerated example, but nonetheless, shows why you lose more power the higher the scan angle. This is also one of the reasons for wanting the ScanPro50s, they have an angled scan block, as well as...

Chroma is horribly inaccurate, and as qumefox said, it doesn't take beam visibility into account. @vk2fro, don't forget, there's always the divergence issue. A divergence of 2.5 (compared to 1-1.5 for a corrected 445 or 532nm beam) will be clearly noticable, not to mention an average value of...

This is why less 473nm would be needed to match an equivalent amount of 532nm, but why 473-only color blends came out looking like absolute crap. 445nm is not as bright, but is a 'bluer' blue than 473nm, by far. From what I've seen and heard, 445 to 532nm is in the ratio of 1:1. Although the...

If you're aiming for brightness, then I would actually suggest a high-power red diode. These usually do around 200-350mW (depending on the type of diode and drive current). They threshold (begin lasing) at around 60-75mA, and at 50mA, they are extremely bright, yet still well away from lasing...

Problem is, the nature of these multi-emitter diodes results in a rectangular beam profile at aperture, and there's nothing that can be done about that. All the FAC does is ensure both axes have the same divergence value, the FAC cannot 'squish' the beam into a square at aperture. There are...

It's just a common side effect of DPSS lasers- none of them will have a true linear curve when modulated through the pump diode. Remember, you've got a separate laser system running inside, with it's own needs. As Leodahsan said, the crystal assembly (both Nd:YVO4 and KTP) are temperature and...

Yes, people do actually hire them, most times just leaving them running in Auto mode in a corner of a room. Green only (30-50mW units) go around $50-$75 per night, while RGB projectors with ILDA support (and a DAC) go for up to $300 a night. It's not bad; it could be worse, and given these...

I said: All Chinese scanners (that us hobbyists use- I'm yet to see any EyeMagic or 6215 clones) are copies of the CT6800 family As a result, when compared to the orignal CT6800s, they are of a low standard (i.e. crap) Some are better than others, though, and perform to an acceptable standard...

Degrading scanners.... WTF ? That's a start. Want more results? Just search. Or talk to Things here, he's one of many who's owned Sonima, and agrees that DT is much, much better. I wasn't saying all Chinese scanners were crap, I was saying that it could be better. Much better, especially at...

The SpaceLas galvos are good for their price, but in the grand scale of things, there will always better. They're not bad, as a matter of fact, and are generally held in much higher regard than ScanPros. Nonetheless, though, DT galvos are better-built than SpaceLas units. A step up from Dragon...

The PT-40Ks are the same price as the DT30s (find a good supplier, and they should be the same). The DT30s aren't rated for as high a speed as the PT-40Ks, but the build quality is substantially better.

Word of advice. They're made by Sonima. Avoid them like the plague. They're 'good enough' for what they are, but they could be better. You get what you pay for, and frankly, these really aren't worth it. Pay a little more, and get DT30s, or just stick with SpaceLas. All the cheap Chinese...

I'm not talking about the Nd:YVO4 being 'tuned'. I'm saying there may be impurities within the YVO4 structure, that, as a result of energy transfers between the Nd+ ions and the respective rare-earth metal ions, are causing them to lase. The optical coatings on the faces of the KTP and YVO4...

Well, what could be happening is that there's some other dopant in the crystal. The Chinese aren't exactly the best with their quality control, and, well, other 'stuff' (often with their own transitions) makes their way into the vanadate along with the intended neodymium. At such low powers...

I still own a few 486 machines that work fine. There was nothing wrong with the 486 generation of processors. Now, if Intel lived off the same motto, we'd be using said 486 processors today. They still work fine, don't they? What's wrong with that, then? And of course, Intel would still be...

Their software is the best in the industry, I'll give them that. LivePRO, for example, is the only comprehensive software for running a live show. The fact that their software is the best in the industry is partly a result of their hardware. Speaking of their hardware, and I quote: How long...
