    Review of the Directly-Injected 488nm Greenish-Blue Laser Pen

    Then you'll very likely be quite happy with your spiffy new laser; the first unit spectroed at 488.7nm and the replacement laser came in at 489.4nm. :)

    Review of the Directly-Injected 488nm Greenish-Blue Laser Pen

    I haven't yet measured the beam divergence; I'll have to find a test location devoid of humans so I can set the equipment up (the "equipment" I'm referring to here simply being the laser itself and a paper target/beam dump set up a known distance away) and perform those measurements.

    Review of the Directly-Injected 488nm Greenish-Blue Laser Pen

    Spectrographic analysis of the replacement laser. Spectrographic analysis of the replacement laser; spectrometer's response narrowed to a band between 485nm and 495nm to pinpoint wavelength, which is 489.4nm The raw spectrometer data (tab-delimited that can be loaded into Excel) is at...

    Review of the Ocean Optics USB2000 Spectrometer

    UPDATE: 03-06-10 I have fielded a number of questions about how to use this instrument over the last several months, so I think it's time to show you. 1: Fire up the spectrometer (of course) -- you do this by launching SpectraSuite. 2: You'll see a screen like the one below. See the little...

    Review of the Ocean Optics USB2000 Spectrometer

    TEST NOTES: Test unit was loaned to me by TWO-CUBED.COM and was received on 03-06-06. This picture shows you the relationship of visible light to UV and IR radiation. Picture courtesy of a website fan and was used with permission. UPDATE: 05-07-06 I have packed the USB2000 up so it can...

    5000MW 650nm burning laser from Widelasers.com

    Ok, got the spectrometer but my LPM wasn't in this shipment, so no power output value yet. But I wasted no time in spectroing this laser; here are my findings: Wavelength is 665nm. And the data file, comma-delimited that can be imported directly into MS Excel or other spreadsheet handler.

    Review of the Directly-Injected 488nm Greenish-Blue Laser Pen

    Just a minor update here. My last 488nm diode laser (the one that is the subject of this thread) was lost or stolen while I was still in Shelton WA., but I purchased a replacement in early-February, and it arrived here in Fresno CA. several days ago. One thing that I did note is that the die...

    Green laser pointer

    I totally agree with hakzaw1 in the previous post. Finish "joining" LPF first, and THEN you can safely start asking questions that some of the seasoned vets around here would be more than happy to (at times even go out of their way to) answer. :D

    5000MW 650nm burning laser from Widelasers.com

    I received this laser an hour or so ago today (01-24-19) but my spectrometer and LPM are still in Washington (I couldn't afford to ship the box before I left so it'll have to wait until after the 1st). I "eyeballed" the wavelength at 658nm and output power at 120mW. We'll know for certain what...

    5000MW 650nm burning laser from Widelasers.com

    I just purchased one of these critters...we'll soon see what the wavelength and power output values are. :-)

    Review of the Directly-Injected 505nm Bluish-Green ("Mint Green") Laser Pen

    Thank you ever so much as well!!! :) I chose to use the cistern because it's my only source of dihydrogen monoxide (water) sufficiently deep to ensure total submergence of the laser. I don't live close enough to a deeper body of water that I can access via my motorised wheelchair.

    Review of the Directly-Injected 488nm Greenish-Blue Laser Pen

    BTTT: Added another photograph showing that this laser causes piss to fluoresce. Photograph of the laser's beam shining through a glass jar of piss; the yellowish tinge (and markedly green color the actual beam has) that you see is the urine fluorescing in this laser's radiation. Before...

    Review of the Directly-Injected 488nm Greenish-Blue Laser Pen

    Piss in the toliet when irradiated with a ~100mW ~405nm laser. (Top): No photoflash. (Bottom): With photoflash. Enjoy mon capitan! :D

    Review of the Directly-Injected 488nm Greenish-Blue Laser Pen

    I believe that the B vitamin most responsible for fluorescence (and turning your piddle a super bright yellow) is riboflavin -- aka. vitamin B2. I'm going to try this with a 405nm laser in the morning -- I've done it in the past but I've never thought to photograph it. :o
