Confocal Operation with Multi-photon

Detector Filters and Barrier Filter

The Super HyD detectors have a 620 nm barrier filter in front of them to protect against reflected IR

light. For bandwidth selection, you will need a suitable filter in front of the detector or detectors. Ask us

how to set this up.

Start Up

It is not necessary to power down the computer or the microscope when switching from

MP_LASER_OFF to MP_LASER_ON operation. However, certain steps must be followed for the
correct sequence.

Switch on the Electro-Optical Modulator.

The modulator is ready for use immediately, but does not

achieve full modulation depth for about 15 minutes. Switch it on

first

.

Switch off the Compact Supply Unit at the back of the table.

Switch on the Super-HyD detectors power and cooling unit.

Switch the Compact Supply Unit back on.

Application Start -

Select

MP_LASER_ON.
