Emission Spectra for LEDs

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

Detectors

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.

Sensors

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

Sensor Model Specifications

Magnetometer Freescale, MAG3110FCR1 view
Hall Effect Sensor TT Electronics, OHS3150U view
PAR light sensor AMS-TAOS USA, TCS34715FN + 700nm low pass filter view

Filters

The MultispeQ v2.0 has two filters, a Band Pass filter covering the visible light detector (#3) and a Low Pass filter used in the PAR sensor.

Filter Model Specifications
Band Pass Schott, BG-18 1mm thickness view
Low Pass UQC Optics, Hot Mirror HM-07 view

Indicator Lights

The MultispeQ v2.0 has now two indicator lights. One to indicate if the device is charging which is located next to the micro-USB port. The second one is located on top to indicate progress or required actions.
