Gamma Scientific has expanded their family of SpectralLED Tunable LED Light Sources for camera and image sensor calibration with a new system having a substantially larger output port, as well as increased output uniformity.  Specifically, the new SpectralLED RS-7-2 mates up to four LED light source engines together with a 1 meter sphere that includes a 300 mm output port (other sphere and port sizes are available, as well).  The result is a calibration light source for very large area detectors and large field of view cameras that delivers significantly higher brightness and approximately an order of magnitude higher radiometric stability (<0.1%) and wavelength accuracy (0.25 nm) than any competitive product.

New signs and display panels improve navigation through Lyon St. Exupéry airport. LED modules and LNU dimmers from Tridonic ensure optimum readability of the signage in all areas of the buildings at all times of day and night. The brightness of the light sources is adjusted according to the amount of ambient light, reducing energy consumption by around 40 percent compared with a standard LED solution.
