Sanwa LP10 Laser Power Meter
Manufacturer: Sanwa Electric Instrument Co., Ltd
Model: LP10
Features
The CW laser power meter measures from 0.01μW to 40.39mW and supports wavelength customization from 400 to 1100 nm. Its compact, pocket-sized design includes a separate light sensor probe, a 4039 full-scale count, and a bar graph display for precise readings. It directly measures laser power at 633 nm and adjusts for other wavelengths using a spectral sensitivity table. Additional features include MIN/MAX hold, diffusion sheets to reduce “return light,” and an auto power save function. Calibrated at 633 nm, the LP10 also measures wavelengths between 400 and 1100 nm using the included chart. You can request direct calibration to any wavelength within this range with a one-month lead time for customized accuracy.
