GOSSEN Foto- und Lichtmesstechnik – Your Guarantee for Precision and Quality
GOSSEN Foto- und Lichtmesstechnik is specialized in the measurement of light, and has decades of experience in its chosen field. Continuous innovation is
the answer to rapidly changing technologies, norms and markets. The outstanding quality of our products is assured by means of production in Germany and a
certified quality management system in accordance with ISO 9001.
Illuminance (abbreviation: E, unit of measure: lux)
indicates with how much intensity an area is illuminated. It amounts to one
lux when a luminous flux of one lumen illuminates a surface of one square
meter. This corresponds roughly to a normal candle flame at a distance of
one meter.
Luxmeters are used to measure illuminance at horizontal and vertical
surfaces. However, illuminance does not indicate the brightness impression
of a room, because this depends to a great extent on the room’s reflective
characteristics. A white room gives a much brighter impression than a dark
room.
With normal lighting, uniform light distribution is not achieved as a rule,
for which reason specifications in the standards usually make reference to
average illuminance. This value is calculated as the weighted arithmetic
mean of all illuminance values in the room.
Applications
GOSSEN’s precision luxmeters are used for planning, installation, testing and
monitoring of lighting systems, as well as for adhering to lighting conditions
for hygienic, physiological, psychological and/or safety reasons. Scope of
validity, terminology, responsibilities, requirements and practical guidelines
are set forth to a great extent in the standards.
Reliable measurement results with defined error limits are guaran-
teed by luminance meters and luxmeters classified in accordance with
DIN 5032-7 and DIN EN 13032-1. This ensures that quality inspections,
reference measurements and assessments conducted with these meters
deliver accurate statements.
Calibration certificates and recalibration at regular intervals are required for
use in quality-relevant applications and for assessments. The GOSSEN Light
Lab offers these services, even for products from other manufacturers, and
issues factory calibration certificates. The optical bench used for this purpose
is subject to strict test equipment monitoring, and is retraceable to the PTB
in Germany (Highest technical authority under the auspices of the Federal
Ministry of Economics and Technology). Aside from the PTB, our lab is
the first in Germany to be accredited for illuminance by DAkkS (German
accreditation authority), and is thus authorized to issue internationally
recognized DAkkS calibration certificates. This assures that acquired
measured values comply with official regulations and norms, which also
stand up to legal argumentation.
Longstanding customers from industry, the public authorities and the field
of medical engineering hold the products and services offered by GOSSEN
Foto- und Lichtmesstechnik in high esteem, are pleased to receive our expert
advice, and ask us to implement their special requirements.
