Thank you! The first idea would certainly work on a stationary object, but unfortunately since the scanner could be used on living specimens we will need some sort of way to constantly keep track of the position of the specimen (This is going to be compounded by the fact that we will be...

Hello All! I am working on a scanning experiment, and had a question about using lasers to find the location of the specimen inside the scanning head. I was planning to use two lasers, which would project a laser grid onto both sides of the sample, from both sides of the main optical train...

Thanks! That certainly helps a lot! I presume that the leftmost image is the internal thread? Also; Is this legal to use, or shall I cite your schematic in my resultant paper as a technical reference? What is your preference?

Hello! I'm working on a retinal projector that uses a RGB laser system. Of course, I will be testing the rig extensively and have safeguards implemented before applying for authorization to test it on humans. I have a question pertaining to the dimensions of the Aixiz modules for 3.8mm...

Greetings. Thank you for all the feedback on this matter. The main problem is not finding the pointers themselves, rather actually modifying them with the IR filters. I will act on your feedback and get back to you. That's the thing, we can't give 200 schools 'class 2' pointer which leak IR...

Greetings. I am looking for a source of low price 532nm laser pointers/ seld-contained modules. The power must be <1mW, and they must be filtered for 808 and 1064nm. I am looking to buy 200 of these, and have checked out dealextreme, o-like and Tmart. The problem was that none of them...

Greetings, gentlemen. Actually, A tunable HeNe is on sale in sam's classifieds, with ALL the visible HeNe wavelengths Avalable At the turn of A knob! Incidentally, the cost is 2000 usd. I Am in NO way Affiliated with Sam's Laser Faq. I just wish to spread the information.

Just A trick I picked up. If my Account is hacked, the poster will not follow this simple rule, And thus will be exposed. Kind of like A sig which you copy into your post, manually. When I get the pump, A review will be forthcoming.

Re: FS -SYD,AU- LaserPhysics Argon Laser Yes. I recognise the newness of the system, And it's practically nonexistant hours, But the price seems too high (for me) I will readily buy An Argon system for 200eu (266 dollars) shipped. Kind Regards, Ivan Kozlov.

Thank you for All your help. I have purchaced A pump on ebay, capable of 30 microns base pressure, for 238 dollars. (w/shipping). The company was recommended by the belljar, And that was A crucial factor. You can improve the ultimate vacuum quite easily. (using A trap) Actually, this pump is...

A 2-stage could, given enough time and A zeolite trap. I may have to purchace/create A diffusion pump later. But for now, Any offers would be great!

Amusing As it is gentlemen, I still need to purchace a pump. Could we mabe head back to topic?

course I do:eg: Buy it new, half the fun's gone EDIT: are you sure it can go down to 10 microns?

Greetings to All. Just wanted to throw this out there, in case someone has such a beast lying around. I am looking for a mechanical vacuum pump capable of reaching 10 microns and below (used, of course). For this cause, I offer 150 eu, which is 200 dollars exactly. Also looking for a vacuum...

Merry Xmas! Please count me in for the diodes!
