The "Magic Sabre" 2W High-Wavelength 454nm Build
This is the latest "Sabre" build I've tackled. It follows in the footsteps of the twin sabres built several months ago here, and adds something new: polarity-free "Magic". This build is completely polarity-agnostic. As long as both cells point in the same direction, you can insert them however you want, and the driver will make it work!
The diode was intentionally binned for high-wavelength, and at 454nm on the spectrometer, it's a beautiful blue. I'll echo what I said in the earlier thread. Our eyes are much more sensitive to light in the higher blue wavelengths, and it's amazing how much brightness the high wavelength adds here. In addition to the brightness benefit, you can definitely tell the difference in colour vs a diode that is hitting closer to 445nm.
This build runs on 2x 26650 cells. You can also use adapters (which I'll provide if you'd like, just remind me) for 18650s instead. It is a remarkably stable build. In the attached LPM chart, you'll see that it held within 10% of it's 2W rating, for the full 5 minute run time.
I only ship via fully tracked and insured methods. Please PM me for a shipping quote.
You MUST own laser protection goggles appropriate for this wavelength, and
You MUST be over 20 years of age, and
You MUST be familiar and experienced with the appropriate safety precautions to take with lasers of this power.
You MUST NOT be a resident of Canada
This is not a laser pointing device. At all times, protective laser safety glasses appropriate for this wavelength must be worn by the operator. This laser should not be used around 3rd parties (non-operators) pets, or for any recreational purpose.
