LP10
Pocket CW laser power measurement from 400–1100 nm.
- 400–1100 nm
- Made in Japan
- Si photodiode
The SANWA LP10 is a pocket laser power meter for CW laser measurement from 0.01 µW to 40.39 mW. It gives direct readings at 633 nm, with a spectral-sensitivity conversion table for other wavelengths from 400–1100 nm. Bhumika, SANWA’s authorized Canadian distributor, quotes this model for laser measurement users in Canada and the USA.
