Hello guys,
I want to introduce my new laser's collection item - 473nm laser pointer.
This is very rare to find thing like this on local auction portal, especially in European domain but some time it happens :yh:
I hope it's good bargain:
- used but like a new
- ϕ180x25mm aluminium tube with "sexy" cyan strip
- DPSS 473nm
- TEM01
- divergency 0.9mrad (calculated by pseudonomen137's calculator)
- power around 18-20mW with 37mW peak (measured by my dirty LPM)
- 1x18650 baterie with charger
- price $140 (converted form CZK)
It's history is unknown but from some chinesse factory. The man who sold it says he bought it in 2008 with emphasis to long duty cycle and needed it "for pointing" for thermal imaging (i don't know why expensive blue and not green???).
Other thing is TEM01 mode. When started it is in TEM00 and after 30sec has been changing to TEM01... but i think it is not such a big disadvantage for LP.
When i saw its color for the first time i was a bit disapointed because of there weren't big color's difference against 450nm LP - it seems to me for the first look (when i compare 532 vs. 543nm i feel bigger difference) So although it was not love for the first look for the second it already is :beer:
Sum up:
Pros: price, price, price..., color, design, easy using
Cons: unknown origin, TEM01, soft trigger, no lock
Regards,
Beam
Btw. be patient with my Czenglish, please...
