Our story
Two Global Leaders.
One Complete Solution.
Konica Minolta Sensing Americas provides
advanced optical technology that precisely
measures the elements of color and light. Their
products have become a staple in research and
manufacturing environments, helping organizations
to meet product quality and operational goals with
less waste, time, and effort. This commitment
to creating value for customers is the core
principle behind the Konica Minolta brand, and
has led them to develop the world’s first portable
spectrophotometer and the first light meter used on
board a spacecraft (Apollo 8). It’s also the driving
force behind the high level of quality and precision
built into each of their products. These are some of
the reasons why Konica Minolta is regarded as the
technological leader in color and light measurement
solutions today.
Based in Germany, Instrument Systems develops
and produces high-quality optical test and
measurement instruments for a broad spectrum
of applications. Their extensive product range
includes spectrometers, imaging photometers
and colorimeters, goniophotometers, integrating
spheres, and turnkey system solutions.
Instrument Systems is dedicated to working with
standardization committees and associations
such as ICDM and CIE. They also cooperate with
leading national metrology institutes.
Now, these two experts have combined
their knowledge and tools together to offer
the complete solution for the most accurate
measurement of light and color available in the
market today.

Product Highlights
Temperature range from +5°C to +85°C (TEC heating
and cooling)
Interchangeable sockets for all common high-power
LEDs and small Level 2 printed circuit boards
Accuracy to 0.1°C
Maximum LED power rating of 10 W
High-Power Also Means
High-Temperature
The temperature of the LED’s chip has an enormous influence
on the light output emitted and on the radiation spectrum
(LED color). This interdependency must be taken into account
particularly in the case of high-power LEDs because the high
operating temperatures lead to an undesirable deterioration in
performance (i.e. reduction in their light output). To be able to
integrate high-power LEDs successfully in final applications, it
is therefore essential to understand the optical properties as a
function of the temperature.
Modular Design for Flexible Usage
The modular system consists of the basic LED-850 unit with
Peltier element and heat sink, and a socket (with centering cap)
specifically matched to the respective model of high-power
LED. A mechanical locking lever locks the centering cap securely
in place, guaranteeing correct mounting of the LED every time.
The centering cap also provides the electrical connection.
Measuring Thermal Behavior with
the LED-850
TEC test adapter LED-850 enables the influence of electrical
and thermal operating conditions on the optical parameters
of high-power LEDs to be assessed quickly and easily. A
Peltier element with cooler fan is used to cool or heat the test
LED within a range between +5 and +85°C. What’s more,
the integral PT100 sensor and the Peltier element can be
connected to a TEC controller that controls and displays the
temperature. Robust test probes also ensure reliable electrical
contacting of the LED.
Two types of centering caps are available:
A sand-blasted, white anodized cap for measuring the
luminous flux using integrating spheres (this centering cap
belongs to the scope of delivery of the LED socket)
A black anodized cap for measuring the luminous intensity
using CIE compliant, LED25-xxx series averaged LED
intensity adapters (cap optional)

Rapid Change-Over of the
LED Socket
The LED socket can be changed over easily and quickly. The
modular design principle makes it possible to test various types
of LED using just a single base unit and interchangeable sockets.
The range of LED sockets (with matching centering cap) covers
all commonly available high-power LEDs from the world‘s leading
LED manufacturers, as well as Level 2 printed circuit boards
(e.g. Luxeon Star). Customer-specific adapters can also be
supplied on request.
The temperature of the LED is controlled by means of a gold-plated
copperzirconium rod that is pressed against the heat-conducting
slug of the LED’s housing by springs. The high thermal conductivity
of the copper-zirconium rod and the Peltier element – with maximum
cooling/heating capacity in excess of 120 W – allow the temperature
to be set quickly to the desired value within a range from +5 to
+85°C. In addition, a large heat sink and a fan assist efficient
dissipation of the heat loads. This results in temperature control
times of just a few minutes. What’s more, a PT100 temperature
sensor that guarantees setting accuracy down to 0.1°C is housed in
the copper-zirconium rod beneath the contact surface for the LED.
Setting time from ambient temperature (Tu=23°C and 35°C) to 15°C; LED power
dissipation 5 W; Peltier power rating 50W; PID parameters: P=80, I=0.3, D=0
Efficient Heat Transfer Using A
Copper-Zirconium Rod
Precise 4-Wire System for
Electrical Contacting
Electrical contacting of the LED is provided by a four-wire
system, a set of test probes and contact springs in the
centering cap. This enables not only the operating current to be
applied but also the forward voltage to be measured precisely
at the same time. TEC test adapter LED-850 is rated for LED
power ratings of up to 10 W. The test probes can easily be
changed by users themselves.
Power Supply and TEC Controller
Instrument Systems recommends the 5305 TECSource made
by Arroyo Instruments for controlling the temperature. We have
developed control software for this device that is included in the
scope of delivery of the LED-850. This userfriendly software can
be used to automate measurements. A Keithley 2400/2600 series
sourcemeter is highly suitable as the current source. Instrument
Systems has developed software for this device, too.
Thermal simulation results: The LED is efficiently cooled and the heat at the Peltier
element dissipated by means of the heat sink
