Laser power meters are extensively used in laser-equipped laboratories to measure laser powers and observe the continuous wave (CW laser). They are used to analyze lasers within a particular wavelength and intensity range.
The silicon photodiode-based LP1 laser power meter has a spectral range of 400nm to 1100nm. It uses 633nm of He-Ne laser as a reference wavelength. The spectral sensitivity conversion table given with the apparatus is used for the characteristic measurement of wavelengths between 400-1100nm. It can be installed conveniently, has a small volume, and shuts down automatically after half an hour to facilitate power saving.
ConductScience offers rodent laser power meters.
