    Default Review - 100mw 473nm Lasever module

    Ok ive only been able to test this for a few mins in my projector.

    this is a great module, i love its small size. makes it great for fitting into a scanner.

    the psu gets mega hot and does need some serious cooling

    The module starts at 40mw and after 5 mins of warming up goes to 122mw and seems to stay around that power. There is hardly any scatter at all from this laser, this module has analogue blanking.






    the unit is focusable which i did adjusted slightly




    the module does have a great beam

    its about 2-3mm at apeture



    and measures about 8-10mm at 16 metres

    Looking good man! Cant wait to see some white light pictures!

    I remember reading somewhere that the Power Supplies needed a lot of cooling otherwise you could damage the head. Cant remember where I read that, I think it was something that David mentioned at one point.

    and maby have a fan blowing into the PSU ?
    I like the smal modules of lasever, but because of the heat problems, I have not ordered any lasers from them.

    So IF a fan is blowing directly over the PSU will be fine??
    Maby an 60mm fan?

    Mounting the PSU to a piece of aluminum makes a world of difference. If you really wanna fix the problem though, I just wire tied a regular el-cheapo computer fan through the holes in the PSU case and it more than gets the job done. Also keep in mind you don't need to worry about keeping the PSU as cool as the laser head. The head should normally be kept as close to room temp as you can, the electronics on the PSU are usually spec'd to a good many celsius above ambient temp though.

    mounting the psu on ally plate will make a world of difference but make sure that your optics lasers and scanners are not mounted on the other side. I know you were talking about a split level system - if that plate is the divider you may run into alignment drift as it all warms up - you will never eliminate this ut you can minimise it by keeping everything cool.Therefore it may be better to have 2 plates close together with an air space between - even if its only a few mm. Then you can have your fans moving air across the psu plate on both sides and it will move some air from the laser plate and assist cooling there without having fans in the optics area.

    If you need to ask the question 'whats so good about a laser' - you won't understand the answer.
