Portable Spectroradiometer

Majantys Probe4Light

The Probe4Light is an innovative spectroradiometer for colour and spectral characterization of light sources offering flexibility at a realistic price. Works with all lighting technologies.

The instrument consists of a miniaturized spectrometer-based sensor and all the

necessary electronics embedded in a hand held, stand alone unit. Simply connect the device to any PC through a USB port. Its Windows Graphical User Interface delivers, an immediate, easy to use display of the spectrum as well as the colour parameters such as the colour coordinates, the dominant wavelength, the correlated temperature and the colour rendering index.

The instrument is suitable for diagnostic tests, incoming inspection and quality control in laboratories, as well as factory and on-site testing.

Majantys Master4Light

Master4Light integrates both a current generator and a spectroradiometer as a turn-key solution to the measurement of LEDs. It accurately controls the LED current and voltage while measuring its optical parameters.

The instrument is available either as a bench instrument or enclosed in a rugged case for in-field or factory floor measurements.

Using the USB communication protocol, the instrument offers a single Windows software graphical user interface for monitoring all the LED variables. The current signal may be continuous or pulsed, with various amplitudes and frequencies. In addition, two thermocouple inputs enable the measurement in real-time of the temperature of the light source under evaluation.

The spectrophotometer delivers the spectral characterization. The software delivers, an immediate, easy to use display of the spectrum as well as the colour parameters such as the colour coordinates, the dominant wavelength, the correlated temperature and the colour rendering index. Analysis tools such as the complete spectrum and alarms are also available.
