Emission Spectra for LEDs

Emission spectra for LEDs build in the MultispeQ v2.0 - Emission normalized to maximum emission peak


The MultispeQ v2.0 comes with two detectors. One covering the near infrared on the main body, the other covering the visual range on the leaf clamp.

# Detection Range Model Specifications
1 700nm - 1150nm Hamamatsu, S6775-01 (main body) view
3* 400nm - 700nm Hamamatsu, S6775 (leaf clamp) view

*Note: The detector 3 is covered with a BG-18 bandpass filter with a center wavelength around 493 nm. If you are using the detector to detect signals on the edges of the detection range, expect the signal strength to be low.


The MultispeQ v2.0 has a set of sensors to measure the environmental parameters
