VLPM100 is a portable automatic range test instrument. It uses professional photoelectric detection probes and high-precision low-power digital chips. The detectors are strictly calibrated for spectrum and angle characteristics, with stable performance and strong applicability. Temperature correction is used to improve accuracy. It can be used to measure the irradiance of sunlight (300-1100nm), and can also be used to test solar simulators, simulated sunlight xenon lamps, LED light sources, xenon lamps, halogen lamps, monochromatic light, etc.

VLPM100 digital handheld optical power meter consists of two parts: main unit and detection probe. The measurement results are directly displayed on a 7-inch touch screen, which is convenient for observation and recording.
