Stabilized Xenon Flash: The Sharp Platform
PHOXENE Sharp platform
In 2018 Phoxene launched the Sharp »platform, based on a patented technology for regulating – in real-time- the light emitted by a really compact flash device.
This flexible platform powers three on-the-shelf products:
- Sx-1 unit: for stroboscopic pulses with a high stability in light emission over the entire life of the flash unit.
- Sx-2 unit: for plateau pulses of light, with constant output power over each pulse. This type of strobe is the ideal fit for rolling-shutter cameras.
- Sx-3 unit : compact flash strobe for short and mid-range illumination.
- Sx-IP unit : IP64 flash strobe for outdoor application.
Sx-1: A Xenon strobe for regulated light pulses
Designing a strobe able to produce pulses of light with constant output is very challenging: a flashlamp tends to behave differently at each shot, and loses overall efficiency when ageing occurs, hence reducing the amount of light produced for a given energy.
Sx-1 strobe, based on the Sharp platform, brings a solution and opens the way to many possibilities in terms of image processing and analysis.
A patented light regulation system
Sx-1 flash unit is fitted with a patented retroaction system for light regulation. This enables a real-time adjustment in the amount of energy injected to the flashlamp, leading to a very stable pulse-to-pulse production of light. Furthermore, this system balances flashlamp’s ageing and ensures a high stability in output over its entire lifespan.
Accurate and stable colors
Sx-1 flash unit also ensures superior color rendering thanks to Xenon flash large spectrum. Particular attention has been given to stabilize the color of light on the X, Y and Z axes.
A short and powerful pulse
Sx-1 flash unit for industrial applications produces an intense pulse of light out of 2.5J energy, with a pulse duration of 60µS. It addresses primarily machine vision applications where LEDs cannot compete – i.e. very short exposure times and/or mid- to long-range.
Sx-2 : A plateau-shaped pulse of light
The combined retroaction and discharge control implemented in the « Sharp” platform leads to a regulation of the power in emission of light. This way it is possible to create plateau-shaped pulses of light which are very stable in power from the beginning to the end of each full pulse.
Sx-2 also allows to adjust the duration of each plateau, with a maximum duration of multiple milliseconds, which enables the use of a rolling-shutter camera.
Sx-3 : A very compact and powerful Xenon strobe
With its ability to produce powerful pulses with a high repetition rate (1Hz), and with a long life of its lamp (1 Million shots), Sx-3 excels as a compact, active-cooled, mid-range (<15m) Xenon strobe for image capture.
Sx-IP : A IP64 and Versatile Xenon strobe
Designed with an IP64 aluminum enclosure, the Sx-IP is the perfect flash strobe for many outdoor applications.
Its versatile conception makes it suitable for traffic enforcement and ride photography thanks to its burst capability, or precision farming thanks to its powerful flashes at high frequency.
