    Laser diode chip aperture, lens aperture & wavelength relationships to divergence?

    Re: Laser diode chip aperture, lens aperture & wavelength relationships to divergence Well I went and removed the lens from the 120mw module, got about the same results.

    Laser diode chip aperture, lens aperture & wavelength relationships to divergence?

    Re: Laser diode chip aperture, lens aperture & wavelength relationships to divergence After I get the proper lenses I will make a video and put it out to see. I think that it is just a question of lenses at this point, I can always go tear apart my 120mw laser and pull that lens out but I...

    Laser diode chip aperture, lens aperture & wavelength relationships to divergence?

    Re: Laser diode chip aperture, lens aperture & wavelength relationships to divergence It has to fit in a 12X30mm laser diode module. The one that accepts the TO-5 (5.6mm) diode. This thing goes mounted in the cassette chuck of a microtome so I do NOT have space for a HeNe. It is used to align...

    Laser diode chip aperture, lens aperture & wavelength relationships to divergence?

    Re: Laser diode chip aperture, lens aperture & wavelength relationships to divergence So far so good. I had been googling data, I am using the copper 12mm DTR diode modules, with the Osram PLT-510. At this moment I have been using the lens that is sent with the module, I know it is not ideal at...

    Laser diode chip aperture, lens aperture & wavelength relationships to divergence?

    Re: Laser diode chip aperture, lens aperture & wavelength relationships to divergence This thread is about 3 years old, I hope some of you are still tracking it, as I have a question. I need to keep a beam as tight as possible. at least from about 15mm from the aperture to about 170mm from the...

    OSRAM 10mw PLT5 510 515nm Green Laser Diode

    I have ordered the Blitz Linear driver from Survival Lasers, the International page tossed me a rock, but figured it out and got things ordered. I am interested in probably a buck driver in this case as I plan to power these from a wall wart 8-10 vdc output. We are aiming for a single power...

    OSRAM 10mw PLT5 510 515nm Green Laser Diode

    I just ordered the Blitz Linear from SL, I went to their web page made the order and got this rather terse message telling me that they could not complete the order due to being the international page, some mumbojumbo about the FDA. So I closed that up and started looking for the page that was...

    OSRAM 10mw PLT5 510 515nm Green Laser Diode

    Good info, I will continue to be all ears, thank you very much for all so far. Indeed one of the options is to just build the driver into a wall wart and be done with it but then that means we will need a wall wart for each laser type (or a switch to set it up for the laser in use) . I am...

    OSRAM 10mw PLT5 510 515nm Green Laser Diode

    I have been looking all over the place for a driver for this diode. I am building it into a tool, I have the space, it does not need to be real small, as indeed I could even put the driver in the wall wort, but I am trying to put the drivers in the tool as we plan to use other wave lengths for...

    OSRAM 10mw PLT5 510 515nm Green Laser Diode

    Folks, I have seen a lot of comments about the higher power Osram 510-520 nm diodes, but I am having an issue finding a driver for the 10 mw diodes. I got a driver from DTR but no joy, a little bit too much power for this unit. At the moment I have on a larger power supply the following CC...
