HyD reflected light detectors (HyD RLDs)

If you are using HyD RLDs you have to switch them on before LAS X starts. Otherwise, the
LAS X software cannot initialize the detectors. The HyD RLDs consist of a supply unit (see
Figure 41) and a detector module (see Figure 42).
• The power switch for switching on and off the power supply and the cooling for the
detector module is located on the front side of the supply unit (see Figure 41).

• For image acquisition, activate the detectors in LAS X. The yellow status LED (see
Figure 42, item 2) flashes if photons are being detected.

• The filter cube cover (see Figure 42, item 1) ensures the housing's EMC stability and
prevents light from entering or exiting.
• Never change or remove the filter cube or short pass filter during operation.
Replacement of the short pass filter is only allowed starting from LAS X Version 2.7 or later.
