PS-3703
Photomorphogenesis Effective Irradiance Detector

The PS-3703 is a high quality compact detector for the measurement of the Photomorphogenesis effective irradiance. Photomorphogenesis describes the way in which plants are formed under the influence of optical radiation. Radiation in the red region of the spectrum encourages linear growth, while blue radiation yields small, strong plants. To be more precise, the ratio of the radiation intensities in the range of wavelengths from 690 nm to 780 nm (long wavelength red) to the range of wavelengths from 560 nm to 680 nm (short wavelength red) is of great importance for the plant's biological processes. The detectors is supplied with a 2m long coaxial cable with selectable –1, -2 or -4 type connector for use with Gigahertz-Optik’s range of optometers. This detector can also be supplied with an optional water proof dome cover. Calibration of Photomorphogenesis effective sensitivity in µMol*m_-2* sr_-1 is performed at Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
