Wells I got the comparison pics up and it was quite surprising to see that the new one has more green in it than the one pushed the hardest. You just never know what you are going to get.
My desktop is fried. Unfortunately everything was on it such as my email password and all my other passwords and I'm not going to remember what they all are. The hard drive works and I have it connected with a USB cord with an adapter to my old laptop. Anyone have any idea how I can find what my email login was from the drive or any other passwords for that matter? PM me. I'm kind of desperate to be honest as I need the emails. It has xp on it.
The heat sink came from Ehg I think when he was selling them or maybe it was Moh. Have one more left for the 44 I have coming. That one is the screw down back half type.
Well it looks like way more green in it than my actual Jet 80mW 473nm. Hard to do a comparison though when you are dealing with a 5W difference in output. I had called it 471 just because of what Jordan shows on his site at 5A but that can't be right. Probably is more like 473nm or more. Have to do more comparison tests.
Fantastic, this one looks more like the usual 488nm pics than ~470nm. It's hard to take a proper measurement, but you can compare wavelengths easily with a diffraction grating or one of those cheap portable spectroscopes from ebay ($30). All you do is shine both lasers on the same spot on a wall and look at the dot through the grating. Of course with 5W it might be better to take a picture
OK, I don't get the difraction grating thing as how is it supposed to help if there's nothing to tell me what wavelengths the colors are to begin with? Someone send me a link or links as to what exactly I need to buy from eBay or whatever that won't cost much so I can try and figure some of this out better. I realize its going to be a rough estimate but I would have a hard time sending them off to someone. What should I be reading to know exactly what to do? I would appreciate links rather than just saying look up ........... I'm seriously thinking about pushing that 5A one harder like I did with the 5.5A one to see how far the wavelength will go but I would need to see if DTR has an adjustable sxd-v3 still as I only see the pre-set ones on his site. I could just drive it with one of my power supplies but I think I would rather just set the driver to max and let her rip (hopefully not R.I.P).
The optics are nothing more interesting than a standard legit G2 or 3 element. I have a 473nm Jetlaser at around 80mW so having a laser to compare them to is not an issue. My question is people kind of make it ound as if it is easy to get a good estimation on the wavelength using a simple difraction grating and I just don't see it. If it was so good and inexpensive I would expect most members to be doing it. A simple way of going about getting a pretty nice beam is using a beam expander. I have a couple as in 2x and 5x Dragon laser ones with adapters plus a 3x on the way from Sanwu with adapter but in general I only use them when I'm messing around as in I don't specifically buy one for each laser like some do.
