    Old Laser Product Patents are expiring, grab yours today.

    Lately I have noticed that a lot of the old patents for devices we have used for years have been expiring, General Scanning Inc. for example invented the Laser show scanner and there patent has now expired leaving it free for anyone to copy. As far as I know, It is not possible to re-register...

    Old Laser Product Patents are expiring, grab yours today.

    I have seen lately that a lot of US patents for devices we have been using for years are expiring lately, as far as I know it is not possible to re-register them exactly. But with some design modifications/additions it seams to be possible. General scanning who invented Laser show scanning had...

    GB: 1W 520nm diode information/giveaway

    And you can see here https://www.fedex.com/fedextrack/html/index.html?tracknumbers=804044121913&locale=en_GB&cntry_code=gb that no expense was spared to get the diode shipped this time. Me and Arg both had good intentions right from the start. Sadly we live in a world where postage systems...

    Maybe some apologies are due to ARG.

    GB: 1W 520nm diode information/giveaway

    Some news, I raised this issue with the post office last week and they called me today to tell me they might just have found it, its certainly the right dimensions. I cannot confirm this for a few days as i am away at the moment. I be back to you as soon as possible.

    GB: 1W 520nm diode information/giveaway

    Hi Everyone, Seen as you asked I decided to login to LPF to clear this situation up a bit. I very rarely get chance to login to forums so did not realize the situation had escalated so pardon me for being busy. My Name is Andy, I am the owner of S.C. Laser Shows S.R.L. based in Romania; our...

    GB: 1W 520nm diode information/giveaway

    As said already on PL, I have some "on the way" but certainly I have no guarantee if they will ever arrive but the risk is one I take because I had some spare cash. ARG is doing the right thing to get them from ebay where there are some guarantees because the last thing anyone wants is the...

    GB: 1W 520nm diode information/giveaway

    I think it is good to order more than one Diode before they might vanish into the corporate only world and re-appear later with some huge price tag. Of course they could also re-appear at 50 bucks too but given the demand for them I doubt that. What I find very interesting is how these ebay and...

    GB: 1W 520nm diode information/giveaway

    ARG; What i suggest you do now is to start taking the payments and to keep collecting members to the list; we maybe end up with some people dropping out or more people coming in; in which case maybe we can get two diodes.

    New Nichia 9mm 1W 520nm diode (NDG7475T)

    Re: New Nichia 9mm 1W 520nm diode Prices are certainly dropping already, or I wonder if one was buying from the other :)

    New Nichia 9mm 1W 520nm diode (NDG7475T)

    Re: New Nichia 9mm 1W 520nm diode Instead to wait and then loose time testing: How about doing a "Team Buy", where a team of say 20 members chip in to buy one or two diodes for testing and lens selections for different beam requirements, then the resulting info is given only to the team...

    New Nichia 9mm 1W 520nm diode (NDG7475T)

    Re: New Nichia 9mm 1W 520nm diode CORRECT!!, and according to the datasheet; the optical angles are all fine to create a reasonable beam; but the emitter which is not documented could be much larger and that would certainly blow all theories out of the window. The only real way to know is to...

    New Nichia 9mm 1W 520nm diode (NDG7475T)

    Re: New Nichia 9mm 1W 520nm diode You can shrink a beam indeed but he divergence will go up.

    New Nichia 9mm 1W 520nm diode (NDG7475T)

    Re: New Nichia 9mm 1W 520nm diode Lenses only bring the angles into focus. The line is a focus of the emitter shape, corrective optics make that line more into a circle by compressing it. Divergence grows with emitter widths. Turning a raw diode beam into a spot is collimation of the angles...

    New Nichia 9mm 1W 520nm diode (NDG7475T)

    Re: New Nichia 9mm 1W 520nm diode Noooo!, the angles can always be changed; what cannot be changed is the emitter which dictates everything!!
