MSC15

LEDs enable much greater control of the lighting quality than the technologies they are rapidly replacing. Many international standards now specify requirements for internal and external lighting systems in terms of both ‘quality’ and ‘quantity’ of light as well as in terms of efficiency and life time. Photometry in the lighting industry generally focuses on the intensity (i.e., illuminance) and color (i.e., correlated color temperature, CCT and color rendering index, CRI) of light falling on a surface. LED lamps are extremely versatile in terms of emission spectra, which is why spectral measurement of the illuminance and color has now become essential for any high-end light meters.

MSC15 Light Spectrum Meter    

The compact, hand-held MSC15 light spectrum meter from Gigahertz-Optik GmbH focuses on the precise measurement of the illuminance spectrum, color, and color rendering. Its cutting-edge design concentrates on measurement accuracy rather than unnecessary esoteric electronic features. This makes the MSC15 a high quality LED light meter at an attractive price. The light sensor consists of a fast spectroradiometer that covers a spectral range between 360 nm and 830 nm (V-lambda range according to CIE S023) with a spectral bandwidth of 10 nm. The device also integrates an optical bandwidth correction feature (CIE 214) in order to further improve the quality of the values calculated based on the spectral measurement data.

Excellent cosine response plus a wide measurement range

Another key feature that ensures accurate illuminance measurements of extended lighting conditions is its carefully designed field of view.  Accurate illuminance measurements are only possible with a precise, cosine-corrected entrance optic. The MSC15 light meter has an excellent cosine response (f₂≤ 3 %), at the same time as offering a wide measurement range for  illuminance and color between 1 lx and 350,000 lx.

Intuitive simple color touch-screen operation

The colored touch screen of the device makes it extremely easy to use. Activating and deactivating of individual measurement displays is possible as well via a configuration menu which is implemented into the MSC15 spectral light meter. Uninterrupted operation of more than 8 hours is provided by its lithium ion battery which is recharged via the USB 2.0. Remote control of the device and data read out are made possible by the supplied software.

Application Software

The included software allows control of the MSC15 light meter device via its USB 2.0 interface.  It provides numerical and graphical displays for all the measured parameters. Measurement data can be stored, loaded and exported.  The software also enables the configuration of which display screens are active on the meter.

Store up to 100 Measurements internally

In addition, the MSC15 is equipped with an internal memory  which can be used to store up to 100 measurements internally and read them out via software later (10 meausurements for Firmware <1.62). The device allows the comfortable management of the stored measurements on its screen.

Calibration of the MSC15 Light Meter

One essential quality feature of photometric devices is their precise and traceable calibration. The MSC15 is calibrated by Gigahertz-Optik’s calibration laboratory that is accredited by DAkkS (D-K-15047-01-00) for the spectral responsivity and spectral irradiance according to ISO/IEC 17025. Every device is supplied with its respective calibration certificate.

Over 30 different light, spectral, color quantity & actinic measurements

With over 30 different light, spectral, color quantity & actinic measurements, this versatile light meter for LED and other light sources can work precisely for you in a multitude of lighting conditions in the field, lab or in production.

PAR Meter measurements for horticultural applications

LED grow lights need to be measured in terms of the Photosynthetically Active Radiation (PAR) they produce. An additional function of the MSC15 is the display of Photosynthetic Photon Flux Density (PPFD) in µmol/m²s (400 nm to 700 nm) which is a measure of the total number of photons within the PAR wavelength range that reach a surface each second per square meter area.

Photomedicine measurements

Neonatal phototherapy lamps used for the treatment of hyperbilirubinemia can be accurately measured in accordance with the latest standards and guidance, irrespective of the lamp type or manufacturer. The MSC15 directly displays total irradiance for bilirubin, E_bi (mW/cm²) in accordance with IEC 60601-2-50:2009+A1:2016 as well as average spectral irradiance (µW/cm²/nm) in accordance with the latest American Academy of Pediatrics recommendations.

Human Centric Lighting measurements

Circadian or Human Centric Lighting requires new metrics beyond traditional photometric and colorimetric values (ref. CIE TN 003:2015). The MSC15 directly displays melanopic irradiance, melanopic illuminance (equivalent melanopic lux) and melanopic daylight equivalent illuminance according to CIE S 026:2018.

DALI Alliance tests IEC 62386-209

Enables CCT measurements to be fully automated in the official DALI Alliance tests in accordance with IEC 62386-209 (colour control gear).
