High intensity in any colour required
Phlox RGB backlights are lit by a linear array of LEDs using a light pipe structure to redirect the light to the surface of the diffuser. The CO2 laser etching process of the diffuser allows a combination of refraction and diffusion to improve backlight luminance. This allows up to 80% of the injected light to be re-emitted from the surface with a fan angle of 30°.
Thanks to mathematical modelling, Phlox backlights emit light in a deterministic and perfectly controlled manner. The sophisticated colour mixing control in the RGB illuminations produces a very uniform and stable light in any desired colour.
Reasons to select the Phlox RGB
The luminance of the light ranges from 6.000 to 16.000 cd/m², depending on the actual size. Thanks a fan angle reduced to 30°, most of the light is directed to the camera sensor, therefore the illumination efficiency is improved. The RGB provides a uniformity of over 95% (+/-10%): Phlox delivers each backlight with a data and distribution chart that specifies uniformity and luminance.
Phlox offers a variety of standard sizes for the illumination: 50x50, 100x100 and 200x200 mm.
The Gardasoft LFC 420 is the ideal device to control the output of each channel.
The chromaticity shift is smaller than 10% over the complete LED lifetime. Recalibration (white balance) of the system is therefore generally not necessary, even for colour sensitive applications.
IP65 rating permits the use in harsh environments without the need for additional housing. This reduces the costs but also allows for a more flexible integration.
The RGB models offer a long expected lifetime, with more than 50.000 hours.

Markets and Applications
Phlox backlights are especially useful in applications requiring high uniformity, luminance and chromaticity stability over a long period as well as a high resolution. A typical application besides shape measurement is quality control of transparent objects (structure, cracks and scratches).
