CAS-140CT Array Spectrometers
|
| |
| The CAS 140CT is the perfect instrument for testing all optical parameters of LEDs, OLEDs, and solid-state lighting products. Beyond that, the CAS 140CT’s exceptional accuracy and reliability have made it the time-honored, internationally recognized reference in LED test & measurement, both in the lab and on the production floor. With add-ons such as CIE 127-compliant adapters for measuring luminous intensity and averaged LED intensity(ILED-A and ILED-B), integrating spheres in various sizes for measuring luminous flux, and a compact goniophotometer for analyzing spatial radiation pattern, the CAS 140CT is a turnkey LED measuring system. Thanks to the fiber connection, adapters can easily be changed without sacrificing the calibration. All radiometric, photometric and colorimetric quantities such as color coordinates, color temperature, color rendering index, and dominant wavelength are calculated from each measured spectrum. |

Integrating Sphere
|
| |
|
The various ISP series integrating spheres serve to determine the radiant power and total luminous flux of all kinds of light sources ranging from lamps and luminaires in general to diverse solid-state lighting products in particular.
|
 |
|
| |
| |
| |
LED Goniophotometer
|
| |
| The spatial radiation pattern of individual LEDs, LED arrays, and smaller LED modules are easily determined using the LEDGON 100 goniophotometer. And a special software function provides a convenient and very precise goniometric method of measuring radiant power and total luminous flux. |
 |
|
| |
| |
| |
Precision Test Sockets
|
| |
| Precision test sockets serve to mechanically align the LED and to provide electrical power. Therefore, the LED remains in exactly the same position in the measurement adapter, ensuring reproducible results. Instrument Systems also offers special test sockets with passive and active cooling for operating high-power LEDs. The LED-850 test adapter with active TEC control allows the LED to be set to a specific temperature. |

TEC test adapter and a TEC controller
|
| |
| TEC test adapter allows users to determine the influence of electrical and thermal operational parameters on the optical performance of high-power LEDs. A thermoelectric cooler element (fan assisted) permits cooling or heating of the LED with an accuracy of 0.1°C. In addition, the integrated PT100 sensor as well as the thermoelectric cooler element can be hooked up to a TEC controller for setting and displaying the temperature. |
