24 Jan 2014 Jenoptik has expanded its opto-electronics portfolio to include new customer-specific LED point sources for ultraviolet and infrared spectral range applications. In doing so, the company is adding to its red-emitting point source product group. These new LED point sources have an excellent homogeneous beam emissions area without side radiation and speckle formation. They ensure an evenly illuminated, sharply defined reflection on the radiating surface. The emissions area, shape, and optics of Jenoptik LED point sources can be fully customized and are therefore also suitable for integration into devices with space restrictions. Since they consume little power, the point sources are also ideal for use in mobile, battery-powered devices.
Tailored to meet the requirements of the application, the point sources can be assembled either as a chip solution, COB solution (Chip on Board), or a standard solution in the robust TO housing. Customer-specific COB solutions allow individual point geometries.
The new UV point sources for the wavelength of 360 nanometers are available with a spot diameter of 60 or 100 micrometers in the TO housing. They offer a well collimated radiation with an angle of radiation of up to seven degrees and a high power density focus. UV point sources are used predominantly in medical devices, for instance for blood analysis and fluorescence microscopy.
For applications in the infrared wavelength range Jenoptik offers new IR point sources group for a wavelength of 850 nanometers. These can be adapted to the customer's specific application with a spot diameter of 25 to 150 micrometers. The IR point sources make the smallest focus areas possible for high resolution in optical rotary encoders, as well ensuring efficient coupling to fiber optics for data transfer and a good collimation with high radiances for light barriers and motion sensors.
Jenoptik develops and manufactures customer-specific opto-electronic semiconductor devices that have high-intensity dynamics and are reliable and durable. High-quality LED chips, COB solutions, and a TO housing with an excellent processing capability allow for efficient system integration.
The technology for the new semiconductor devices was developed by Jenoptik and its partners as part of the WideBaSe research project investigating AlGaN-based UV technologies.
