Mavospec Base M521G | Lite M530G from Gossen
Mavospec Base M521G and Mavospec Lite M530G - Spectrometer from Gossen
The MAVOSPEC BASE and the "little brother" the MAVOSPEC LITE are perfect for everyday measurements of all conventional and modern light sources such as LEDs or OLEDs. In every lighting situation - from private housing to the professional and industrial sector - compliance with defined values ??and standards as well as the consideration of quantitative and qualitative requirements is decisive for the lighting effect achieved. The MAVOSPEC light meters support lighting planning, find problems with electrical installations and offer simple light measurement and documentation for every user.
All characteristic parameters such as illuminance, color temperature, color rendering index and much more. are determined from the measured spectrum and clearly shown on the color display. Operation is user-friendly and intuitive via a ring controller and a few buttons.
Versatile application options and a wide range of uses make the MAVOSPEC BASE M521G and MAVSPEC LITE M530G a reliable partner for lighting specialists when it comes to selecting, matching, checking, verifying, comparing and evaluating the light and color quality of different light sources or different manufacturers.
The following calibration certificates are available on request: factory certificate - H997S

Spectral power Distribution - measurable with both devices
represents the radiant power of a light source for a wavelength or wavelength band in the visible range. It provides information about the colour characteristics and can be used to compare the colour composition of different light sources. The colour rendering property can also be derived from this, because missing or reduced areas in the spectrum cause errors in colour rendering.
Color rendering index - measurable with both devices
Ra is a measure of the colour rendering properties of lamps whose theoretical maximum value is 100. The higher the colour rendering index, the better the colour rendering properties of the lamp. The most natural colour rendering possible is achieved by using lamps with Ra > 90. Ra is the arithmetic mean of the color deviation of the first 8 of 14 test colors according to DIN 6169, with the color rendering index Re, calculated across all 14 test colors and the additional test color 15 (Asia Skin Color), which also takes saturated colors, leaf greens and skin tones into account. DIN EN 12464 defines the colour rendering properties of lamps for lighting in different types of rooms and activities.
color coordinates - measurable with both devices
are a measure to precisely define a color or the color location belonging to the color in the CIE standard color system. The human eye has sensory cells for the perception of the three primary colours red, green and blue. The spectral eye sensitivity curves were determined by the CIE for the normal observer in 1931 and show the sensitivity for the individual wavelength ranges.
Flicker - only Mavospec Base
refers to changes in the brightness of the light due to voltage fluctuations. The noticability threshold for luminance changes is a frequency-dependent variable that indicates from which relative luminance change at a given frequency this is perceived. These fluctuations have an impact on human health. A good LED driver regulates voltage fluctuations and avoids flicker. The flicker value is a measure of the quality of the lamp or luminaire and should be as low as possible.
Illuminance strength - measurable with both devices
indicates the intensity with which a surface is illuminated. It is one lux if the luminous flux from one lumen illuminates the surface of one square metre evenly. One luxmeter is used to measure illuminance on horizontal and vertical surfaces. However, it does not reflect the impression of brightness of a room, as this depends largely on the reflective properties of the room surfaces. Under normal lighting conditions, no uniform light distribution is usually achieved, which is why specifications in standards usually refer to average illuminance. It is calculated as the weighted arithmetic mean of all illuminances in the room.
Colour temperature - measurable with both devices
is a measure to quantitatively determine the respective colour impression of a light source. The unit of colour temperature is Kelvin (K). In concrete terms, it is the temperature whose light effect is most similar to the colour to be described at the same brightness and under fixed observation conditions.
Color rendering IES TM-30-15 - only with Mavospec Base
is a new IES standard for evaluating the colour rendering of light sources, which works with 99 reference colours distributed over the entire colour space. It therefore includes considerably more colours and shades in the calculation of the Fidelity index Rf, which describes the same relationship as the colour rendering index Ra. The Gamut-Index Rg provides information regarding color saturation and color shift similar to the Gamut-Area-Index GAI of the previous observation of color rendering.
