3.3.2 OCTOPUS 300
Handle the instrument using both lower housing halves to lift it out of the packing. Two ribbed grips hinder sideways slipping.
Since the OCTOPUS 300 works without a cupola, a fully darkened room is not required. In order, though, to make the examination
conditions pleasant for the patient and for obtaining reliable results, the instrument is to be placed in the room so that no direct light
falls on the instrument or the patient.
The positioning between the patient and the operator or the operating panel can be so chosen that the room conditions are optimally
used.

5PRINCIPLE OF OPERATION
HAAG-STEIT is the only company offering perimeters with direct projection systems (OCTOPUS 300, 1-2-3). By means of the
‘Optical unit’, which is replacing the cupola, stimuli are directly projected into the patient eye. This technique does not require dark
room condition to take a visual field.

5.2 Stimulus Intensity Control
The required dynamic range of the stimulus intensity of 40 dB (1:10'000) is achieved with a combined control mode:
a) Two point current control (I)
b) Pulse-width modulation (S)

Tradition and Innovation
OCTOPUS 300 Service Manual Page 13 / 64
5.2.1 Current Control
Two current reference values (operating points) are ascertained during the stimulus calibration procedure:
Operating point OP1: 0dB (max. stimulus intensity)
Operating point OP2: 20dB (max. stimulus intensity/100)
Thus the entire dynamic range is divided into two segments:
Segment 1 / operating point OP1: 20dB ... 0dB
Segment 2 / operating point OP2: 40dB ... 20dB

5.2.2 Pulse-width Modulation
A typical stimulus of 100ms duration is formed by a burst of 20 5ms pulses. The width (ratio LED switch-on/LED switch-off time) of
the 20 pulses can be increased or decreased by processor control in steps of 0.4s (12'500 steps for 5ms). With a longer switch-on
time the LED is emitting light for a longer time period, resulting to the human eye, which has an integrating characteristic, in an
impact of higher brightness. Pulse-width and light emission are proportional. Pulse-width modulation and stimulus duration are
controlled by the microprocessor software through logic timer signals.

5.3 Background Intensity Control
The light source for the background illumination consists of a number of white LED’s. During initialization of the perimeter the
background brightness is measured by a photo sensor and controlled by a DAC value. Pulse-width modulation is not used for
background illumination.
5.4 Reference Point
During initialization of the perimeter the stimulus projection unit is centered to the optical system (position x/y = 0/0). The photo
sensor for background illumination calibration is used as reference point.
