Note
The MultispeQ v1.0 has been discontinued. Please see the improved version MultispeQ v2.0. In general the Getting Started section from MultispeQ v2.0 applies to the v1.0 too, though calibrations will require a CaliQ adapter.

# Emission Spectra for LEDs
# 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) |
*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 v1.0 has a set of sensors to measure the environmental parameters.
