The compact and user-friendly MSC15 spectral light meter is an inexpensive entry-level light-color-spectral measurement solution for any type of conventional and solid-state light source such as LEDs and OLEDs.

Cost Effective Measurement of Lighting Conditions

The hand-held MSC15 spectral light meter is designed for quick and easy light intensity and color evaluation of all types of light sources. As a spectral light meter it is ideally suited for new technology SSL light sources such as LEDs and OLEDs. Spectral measurement capability is necessary for accurate solid state lighting analysis. In addition to illuminance and color coordinates the MSC15 also determines color rendering indices, tristimulus values, color temperature and light spectrum.

Measurement of Effective Photosynthesis Lighting

In order to evaluate the effectiveness of lighting in ​​plant growth, agronomy, greenhouse design and maintenance, Photosynthetically Active Photon Flux Density, PPFD or short PFD radiation is measured. PAR is measured in quantum units of µmol/(m²s) from 400 to 700 nm. The MSC15 spectral measurement method ensures accurate readings regardless of light source type (natural or artificial).

Measurement of Effective Blue Light Irradiation in Neonatal Jaundice Treatment

Newborn jaundice or neonatal hyperbilirubinaemia, a yellowish appearance of the skin and whites of the eyes, can be treated by application of phototherapeutic blue light irradiation of ideally 459 nm (practice: 450-475 nm). In order to minimize the side effects of phototherapy and ensure proper dosimetry, Bilirubin effective irradiance can be measured and adjusted with the MSC15 spectral light meter.
