MAS 40

Low Cost Entry Level Design For Quality And Precision Measurement Tools For LEDs Lamp.

Instrument Systems MAS 40 mini-array spectrometer is value for money,  very versatile and ideal for application in industrial quality control, research and development work. The MAS 40 meets all the quality specifications guaranteed by Instrument Systems in a spectroradiometer designed for absolute measurement of light radiation in cost-sensitive applications. The full range of accessories from Instrument Systems can be connected to the MAS 40 using a fiber optic cable. This capability allows users to access the full range of applications offered by the instrument.

The MAS 40 mini-array spectrometer requires no dedicated power supply because power is provided via the USB port. This makes the MAS 40 ideal for mobile applications.

Like all spectrometers from Instrument Systems, optical fiber connectivity provides access to all the measurement adapter accessories. This capability supports for a wide range of applications. Flexibility of this nature means that the MAS 40 is also ideal as a cost-effective instrument for
research and development work.
