# Emission Spectra for LEDs

Emission spectra for LEDs build in the MultispeQ v1.0 - Emission normalized to maximum emission peak

# Detectors

The MultispeQ v1.0 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 (opens new window)
3* 400nm - 700nm Hamamatsu, S6775 (leaf clamp) view (opens new window)


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.

# Sensors

The MultispeQ v1.0 has a set of sensors to measure the environmental parameters.

Sensor Model Specifications
