Z760 LED Light Sources are arrays of high-performance light emitting diodes (LEDs) that can operate in multiple regimes: flash, continuous light, harmonically modulated light, or they can work with a user-defined modulation. Different versions of the device vary spectrally from UVA to IR. The device can be used as a stand-alone unit or it can be integrated into other instruments, such as the Z200 Open – FluorCam, Z230 Arch FluorCam, Z150 Photobioreactor. Base LED Clusters can be used to outfit growth rooms.

Instrument Highlights:

• High light output – up to 3,000 µmol(photon)/m2/s at the distance of 20 cm (depends on the LED type).
• Measuring flash duration 10-40 µs
• Uniform light distribution over the desired area.
• Both panel and control unit cooling (automatic control).
• Hardware or software control of the light regime (flashes, continuous light, used-defined modulation), timing, and intensity.
• Different color versions varying spectrally from UVA to Infra-Red
• standard colors available: white cold, white warm, blue royal, red-orange, red, blue, green
• Bi-color, tri-color versions available.
• Long longevity of LEDs (6-7 yrs)

Z130 FytoScope Chamber represents a remarkable combination of a LED-based growth chamber and measuring device.  It provides well defined culture conditions.  The illumination can be controlled in its intensity, spectral composition and temporal modulation.  Temperature, gas atmosphere composition can be constant or varied.  Z130 FytoScope Chamber has primarily been designed for cultivation and monitoring of higher plants.  Alternatively, it can be used for growing algae and cyanobacteria in Petri dishes or Erlenmeyer flasks that are exposed to well defined irradiance, kept in constant temperature and, if needed, supplied by gas mixture (also see Z140 Algaetron).
