Model	Range	Sensor	Display	Power
LP10	0.01 µW – 40.39 mW	Si photodiode, Ø9 mm, diffusion sheet	4039-count digital + 41-segment bar graph	LR44 1.5 V ×2
LX20	0.1 lx – 403.9 klx	Si photodiode approximating CIE relative luminous efficiency	4039-count + 41-segment bar graph	LR44 1.5 V ×2

What should I consider before buying?

Choose LP10 for CW laser measurement from 0.01 µW to 40.39 mW at wavelengths from 400–1100 nm; its direct reading is at 633 nm. Choose LX20 for illuminance from 0.1 lx to 403.9 klx. Both have dockable stick sensors and 4039-count displays with 41-segment bar graphs.

What do buyers usually ask?

Can LP10 be customized for another wavelength?

Factory wavelength customization is offered on special order for any wavelength within 400–1100 nm through an authorized agent.

Does LP10 measure pulsed lasers?

LP10 is specified for CW laser measurement only.

What does LX20 measure?

LX20 measures illuminance from 0.1 lx to 403.9 klx in four ranges, using a Si photodiode approximating CIE relative luminous efficiency.
