QUALITYPRECISION

GOSSEN Foto- und Lichtmesstechnik Your Guarantee or Precision and QualityGOSSEN Foto- und Lichtmesstechnik is specialized in the measurement o light, and has decades o experience in its chosen feld. Continuous innovation isthe answer to rapidly changing technologies, norms and markets. The outstanding quality o our products is assured by means o production in Germany and a

certifed 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 ux o one lumen illuminates a surace o one square

meter. This corresponds roughly to a normal candle ame at a distance o

one meter.

Luxmeters are used to measure illuminance at horizontal and vertical

suraces. However, illuminance does not indicate the brightness impression

o a room, because this depends to a great extent on the rooms reective

characteristics. A white room gives a much brighter impression than a dark

room.

With normal lighting, uniorm light distribution is not achieved as a rule,

or which reason specifcations in the standards usually make reerence to

average illuminance. This value is calculated as the weighted arithmetic

mean o all illuminance values in the room.

ApplicationsGOSSENs precision luxmeters are used or planning, installation, testing and

monitoring o lighting systems, as well as or adhering to lighting conditions

or hygienic, physiological, psychological and/or saety reasons. Scope o

validity, terminology, responsibilities, requirements and practical guidelines

are set orth to a great extent in the standards.

ApplicationsGOSSENs precision luminance meters are used or distance and contact

measurements or all types o light sources. For the purpose o adhering

to applicable norms, this allows or testing o minimum and maximum lu-

minosity, assurance o quality requirements specifed or products with

displays or lamps, ascertainment o maintenance requirements due to aging,

and optimization o illumination uniormity. Scope o validity, terminology,

responsibilities, requirements and practical guidelines are set orth to a great

extent in the standards.

Luminance(abbreviation:L, unit of measure:cd per m)indicates the brightness impression perceived by the eye when positioned in

ront o a back-lighted or illuminated surace. It describes the physiological

eect o light on the eye, and is used as a planning actor or outdoor lighting.

Reliable measurement results with defned error limits are guaran-

teed by luminance meters and luxmeters classifed in accordance with

DIN 5032-7 and DIN EN 13032-1. This ensures that quality inspections,

reerence measurements and assessments conducted with these meters

deliver accurate statements.

Calibration certifcates and recalibration at regular i ntervals are required or

use in quality-relevant applications and or assessments. The GOSSEN Light

Lab oers these services, even or products rom other manuacturers, andissues actory calibration certifcates. The optical bench used or this purpose

is subject to strict t est equipment monitoring, and is retraceable to the PTB

in Germany (Highest technical authority under the auspices o the Federal

Ministry o Economics and Technology). Aside rom the PTB, our lab is

the frst in Germany to be accredited or illuminance by DAkkS (German

accreditation authority), and is thus authorized to issue internationally

recognized DAkkS calibration certifcates. This assures that acquired

measured values comply with ofcial regulations and norms, which also

stand up to legal argumentation.

Longstanding customers rom industry, the public authorities and t he feldo medical engineering hold the products and services oered by GOSSEN

Foto- und Lichtmesstechnik in high esteem, are pleased to receive our expert

SpecifcationsMaximum precision Classifed measurement o illuminance in lx or c in

accordance with class B or class C per DIN 5032-7, appendix B o IEC

13032-1 and CIE 69.

Broad measuring range High initial sensitivity and a resolution o 0.01 lx

or 0.001 c or the MAVOLUX 5032 B USB, right on up to large illuminance

values o 199,900 lx or 19,990 c.

V() adaptation The spectral sensitivity o the silicon photodiode is

color corrected and corresponds to the spectral brightness sensitivity o the

human eye V(). The quality o this adaptation represents a signifcant

dierence between the class B and class C variants.

Cosine correction The luminosity o a at measuring surace is proportional

to the cosine o the incident angle o light. This relationship is taken into

consideration by the sensor during evaluation.

Simple expansion o unctions Unclassifed measurement o luminance

in cd/m2 or L is made possible by the optional luminance attachment.

An additional adapter disc prevents erroneous measurements due to

incidence o light rom the side.

Convenient everyday use Simple operation, easy to read display, compact

design, protection during transport in a high quality aluminum case.

Non-volatile memory 100 measured values can be saved, retrieved or

transmitted to a PC via the integrated USB port. Average illuminance values

can also be calculated as a result.

Computer-aided measurement The meters continuous operating mode is

assured thanks to power supply via the USB port. Meter control, as well as

reading, display and storage o measured values, is managed with GLUX 2

sotware, included in the delivery contents.

MAVOLUX 5032 B/C USB

Due to its outstanding accuracy in accordance with class B, the MAVOLUX

5032 B USB is used primarily or certifcation and inspection applications.

An additional measuring range with high initial sensitivity o 0.01 lx makes

it possible to measure extremely small light intensities. This even permits

reliable measurement o emergency lighting. Ater pressing the HOLD key,

the measured value is saved to memory and display illumination included

with this version is activated, making it possible to read the display in dark

environments. Adaptation to the spectral brightness sensitivity o the humaneye V() is highly precise with minimal deviation o just 1 < 3 %.

With accuracy according to class C, the industrial luxmeter Mavolux 5032 C

USB is primarily used or general applications.The smallest o our measuring

ranges begins with an initial sensitivity o 0.1 lx. V() adaptation deviation,

which amounts to 1 < 7.5 %, is considerably better than the admissible

error limit or class C.

Both variants can be used as unclassifed luminance meters with the help

o an optional luminance attachment with an acceptance angle o 15.

Luminance is measured in candelas per square meter (cd/m) or oot-

lamberts (L), and defnes the perceived brightness o a back-lighted or

reecting surace.

At GOSSEN, great emphasis is placed upon reliability by means ocalibration. For purposes o documented evidence, a actory calibration

certifcate or a DAkkS calibration certifcate can be ordered along with either

variant. Depending on how the meter is used, we recommend a calibration

interval o 12 to 24 months.

This high precision luxmeteris available in class B and class C versions in accordance with DIN 5032-7, appendix B o IEC 13032-1 and CIE 69. Both variants are equipped with V( )adaptation as well as cosine correction, and reliably measure the illuminance o daylight and artifcial sources o light. Even in the case o very bright sunlight or

light rom headlights, no accessories are required.

MAVO-SPOT 2 USBIs equipped with an excellent adaptation to the spectral brightness sensiti-

vity o the human eye V() and is highly precise with a minimal deviation o

just 1 < 3 %, which is signifcantly better than specifed in the standard.

By means o the mirror reex optics, the measuring subject may be targeted

precisely in a 15 feld o view and a sharply marked 1 measuring circle in

the center o the viewfnder. Focus can be set or distances ranging rom 1

meter to infnity. Shorter distances as o 34 cm are made possible by meanso optional close-up lenses. Alternatively, contact measurement can also be

perormed with an optional, top quality probe. The velvety coating on the

adapter disc prevents scratching o sel-luminous and back-lighted suraces.

Measurement unctions are selected and measurements are started with

convenient on-hand operation. The display on the viewfnder is activated

along with back-light by simply pressing a key. The comparative and ratio

measurements are especially advantageous, by means o which deviation

o measured value B rom reerence value A is evaluated and displayed.

The relationship A/B is used or contrast measurement at workstations.

Percentage deviation %A allows or an assessment o the consistency o

monitor screens and projection screen lighting, and dierence A-B is used to

detect deviation during the production process.Special tests or proving and observing norms and standards or quality,

general saety, work protection, as well as saety on monitors in the feld o

medical diagnostics and ofce technology may get its documented evidence

by means o our actory Calibration Certifcate. Depending on how the meter

is used, we recommend a calibration interval o 12 to 24 months.
