Lanfei Optical Releases New Products for LED and Light Source Characteristics


Labsphere Releases Upgraded LED and Light Source Characterization Features The new "Starter and Choice" series of new devices provide users with a complete and flexible optical test solution to meet the growing wide range of light in the Chinese scientific and industrial markets. For testing needs, Labsphere, a world leader in the design and manufacturing of optical test solutions, has released a new line of LED and light source measurement products. Labsphere's products are ideally suited for the development of luminaires and display technologies that China is committed to. The new products in the "Starter and Choice" range include spectrometers, light intensity probes, spectral irradiance receivers, standard calibration light sources, LED space analyzers and the new LightX software platform. The new product range is tailored to the user's research, development and production needs with precise calibration measures and fast test solutions.
The highly sensitive CDS 1100 and CDS 2100 CCD array spectrometers provide full spectral irradiance, luminosity and colorimetric measurements for a wide range of source sizes, providing a broad spectral range covering the UV-VIS-NIR band. This type of electric refrigeration, rear sensitive CCD design features low noise and large dynamic range.
A variety of accessories are available to extend spectrometer performance. The I 1000 and I 2000 probes are used to make repeatable measurements of the average spectral intensity of the LED. To measure spectral irradiance, an E 1000 optical probe can be used with the Labsphere spectrometer for precise measurement at the touch of a button. Using the IES 1000 standard calibration light source, end users can calibrate intensity and spectral irradiance probes to NIST traceability standards in the field. Durable tungsten halogen lamps based on point source standard calibration have a 2000 hour rating life.
In the application of LED space measurement, the LSA 3000 automatic angle measuring spectrometer in the new product range can be used. It can perform precise LED measurements at small angles or wide distributions, as well as plot relative strength versus angle.
The series' accessories are integrated and controlled by Labsphere's Windows-XP(R) and Vista(R)-based operating system, LightX. The software is quick to install, intuitive to calibrate, and easy to use. The user interface is easy to use for both engineering and production line staff.
All Labsphere series components are designed to be compact and ergonomic and easy to transition from research and development to production. The “Starter and Choice” range is versatile and can be selected with the help of the Labsphere sales team to build special-purpose products.
