# 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.
