Laser Power Meters/Environmental Meters

Laser Power Meter



Measurement range (CW laser): 0.01μW~40.39mW
Customization of wavelength to 400 ~ 1100 nm is available by factory default setting.

Made in JAPAN

  • Pocket size.
  • Separate light sensor probe can be integrated with the main body for measurement.
  • 4039 full-scale count with a bar graph display.
  • Direct reading of the laser power of the reference wavelength of 633 nm, while the laser power of other wavelengths can be read by converting it according to the spectral sensitivity characteristic table.
  • Wide measuring range from 0.01 μW to 40.39 mW.
  • MIN/MAX hold functions.
  • The diffusion sheets are used in the sensor, it can suppress the "return light" that is generated when a laser light enters the sensor.
  • Auto power save function prevents wasting of battery power.


Wavelength customization
The standard LP10 is calibrated at 633 nm but can also read any other wavelength in the 400 ~ 1100 nm range using a chart inside the case cover.
We can calibrate directly to any other 400 ~ 1100 nm wavelength for special orders, with one month lead time, so please contact our authorized agent if necessary.
