    SOLD: CNI GLP 485nm

    Re: FS: CNI GLP 485nm It's built by CNI so they are using one of their own lenses. The GLP 485 is sold.

    SOLD: CNI GLP 485nm

    Re: FS: CNI GLP 485nm Upper dot is sharp 490nm and lower dot is the GLP 485. There is extra dot to the right which is just camera reflection. It’s not as bad as it looks on the picture.

    565nm From LaserLandAustralia

    I can’t believe I missed this earlier. I just put my 575nm through the spectrometer and I noticed a small peak of 937nm and shifted up to 940nm as it heated.

    565nm From LaserLandAustralia

    Here is a close up picture of the crystal, it seems that this crystal does all the work as the rest of the setup is just lenses.

    565nm From LaserLandAustralia

    Most of their items shows false description. I can assure you this is 100% laser and not an LED or anything else. The spectro test and the beam characterstics is more than enough to prove that it’s a laser.

    565nm From LaserLandAustralia

    This is the module, only if I can take the back plate then we can know much more about it but this thing is sealed I started from the top by removing the collimation lens which revealed the following (lens ?), anyway it was easy to pop off and here is a close up picture of it Under...

    565nm From LaserLandAustralia

    I got my order of the two 575nm modules from optlaser And the question you are looking an answer for, is it really a 575nm ? well..... Yup, they are 573nm. it doesn't have a wide linewidth like the 565nm. I didn't have the time to do an extensive power testing but they do about 15mW, I...

    SOLD: CNI GLP 485nm

    Up for sale a ~10mW CNI GLP 485nm This one has a Osram PLT5 which known to have some kind of dirty window that add some splash around the dot. Asking $old.

    565nm From LaserLandAustralia

    I ordered two units from the alibaba seller and it should ship tomorrow. I’ll keep you updated on what I find about these, I’ll even tear one apart if it’s 565nm or 575nm.

    565nm From LaserLandAustralia

    I’m wondering if it’s really 565nm or just a mislabeled 561nm. From a quick google search, it doesn’t seem that any company produces 565nm.

    some 488, 495, 505nm pics 4/27/18

    Your photography is simply stunning. I really like the color accuracy of your camera, unfortunately my DSLR picks the whole 485-495 range as the same color.

    Killer deal on USB spectrometer! (update: legitimate!)

    They offer a newer model with "more sensitivity" https://www.ebay.com/itm/Spectrometer-Spectrometre-Spektrometre-hHigh-sensitivity-with-Optical-Fiber-SMA/282905865333?hash=item41de80ec75:g:gcMAAOSw5nFavni3 The real killer deal was the RGB Photonics spectrometers that were selling for $280 on...

    Sharp 490nm GH04850B2G 55mW Laser Diode

    I don't have an exact number for current but I always ask them to do the test around threshold current.. The output of my GLPs are always around 10mW and heat is not a problem for the non-dpss GLPs. I did a test on my GLP-495 and the wavelength increase 0.2nm over a period of 5 minutes of...

    Sharp 490nm GH04850B2G 55mW Laser Diode

    These are the readings of the 6 diodes I sent to CNI. 486nm 487.07nm 489nm 489nm 490nm 491nm I’ll probably have both the 486nm and 490nm built into GLPs.

    Sharp 490nm GH04850B2G 55mW Laser Diode

    Re: Sharp 495nm GH04850B2G 55mW Laser Diode It's interesting how your camera picks the color. Would you call it green or blue from the very first look ?

    Sharp 490nm GH04850B2G 55mW Laser Diode

    Re: Sharp 495nm GH04850B2G 55mW Laser Diode CNI will receive 6 of these GH04850B2G tomorrow so stay tuned for some results. I’m praying for 491nm.
