GOSSEN Mavospec Base Spectral luxmeter

The MAVOSPEC BASE is a highquality, miniaturized spectrometer for routine daily measurement of all conventional and modern light sources such as LEDs and OLEDs. All characteristic measured quantities such as illuminance, correlated color temperature, color rendering index, color coordinates in accordance with various CEI standards, flicker, spectral power distribution, peak wavelength and dominant wavelength are determined for the measured spectrum and displayed such that they can be understood by experts as well as laypersons.

Great variety of applications
Development and manufacturing of lamps and light fixtures
Wholesale and retail sale of lamps and light fixtures
Medical technology
Shop lighting
Workplace lighting
Interior design, lighting design
Exhibitions, museums, libraries
Studio, stage and film lighting
Human centric lighting research
Monitors, projectors, largeformat Screens

Illuminance
Calculation of illuminance based on spectral data. Cosinecorrected measuring probe in accordance with class C per DIN 50327.

Large dynamic range
The meter is capable of measuring values from 10 to
100 000 lx, thus covering a broad range of applications.

Spectral power distribution
Measurement of spectral power distribution over a large spectral range of 340 to 750 nm with determination of the peak wavelength and dominant wavelength.

Chromaticity, color coordinates
Measurement of color coordinates in accordance with CIE 1931 x,y, CIE 1960 u,v and CIE 1976 u', v', and
display of the CIE standard color table.

Light quality
Measurement of the correlated color temperature CCT and color rendering index Ra, as well as individual indices R1 through R15.

Flicker value
Measurement of flicker as an index and as a percentage.

Outstanding measured value stability
The integrated temperature sensor and automatic temperature compensation of the dark stream assure outstanding measurement results over a large temperature range.

Individual calibration
Each spectrometer is subjected to photometric and radiometric calibration prior to shipment. A simple calibration report is included in the scope of delivery.

Convenient daily use
Highly practical onehand operation with the ring controller and just a few keys, easily legible color display with high resolution, compact design, protected transport in a highquality aluminum case.

Automatic measured value storage
Thousands of light measurements can be automatically or manually saved in CSV format to the 8 GB microSD card which is integrated into the battery compartment where it’s well protected.

Easy data transfer
The integrated USB port permits easy data exchange with the PC. The data, which are saved in CSV format, can be imported to any desired programs.

Individual system integration
The open protocol for device control and data communication permits incorporation into the user’s own applications.

Sustainable device concept
The ability to update the device via the USB port keeps it open for future expansions and standards

Ecological power supply
Replaceable, rechargeable lithiumion battery, charging via USB port with external mains power pack, display of charging status and battery level, approximately 8 hours of continuous operation without shutdown.

Extremely long rechargeable battery operating time
Can be extended by reducing display brightness, with automatic display and device shutdown.
