Notes
- To determine laser power:
- Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle P=V/((Amps/W) * (V/Amps)) }
- With Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle V} as the measured voltage from the photodetector, and Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle Amps/W} and Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle V/Amp} as two conversion factors depending on the wavelength of the laser and the gain setting of the detector respectively (page 9 and 11 in user manual).
- Response is consistent from photodiode to photodiode.
- Zero point can shift a few tenths of a millivolt depending on the temperature.
