Position Sensor C7339
(For Laser Beam Alignment)
DATA SHEET
FEATURES
The C7339 Position Sensor is an opto-electric position-
sensing unit which measures the position of a single
point of light spot-focused onto the sensor head.
The use of hybrid circuitry allows for a compact, light-
weight design and a divided configuration with a light,
compact sensor head and a controller equipped with a
light level indicator and data displays for ease of opera-
tion. The measured position is displayed digitally in terms
of X- and Y-coordinate voltages on the front panel of the
controller and may be simultaneously output to a re-
corder.
• Quick Response
The response time of less than 20µs enables accurate mea-
surement of the spot, even while it is moving at high speeds.
• Stable Measurement
The position data (X-Y coordinate voltages) of a light spot is
obtained without being affected by signal current fluctua-
tions from the PSD, enabling accurate position measurement
regardless of fluctuations in the light intensity.
• Broad Spectral Response
The C7339 has a broad spectral range, from 300 to 1100 nm,
enabling the detection of a variety of light sources, including
lasers.
• High Resolution
The C7339 does not possess a background-light cancel-
lation function and is suited for use in locations where the
signal light is distinct from the background such as in the
detection of laser beams.
The PSD employed in the sensor head is of the non-discrete
type, which, contrary to a discrete-type sensor, has no insen-
sitive area. This enables continuous measurement at a high
resolution of 1/5000 (when using a recorder).
• Light Level Indicator
The input light level is indicated in digits on the front panel
of the control unit (0.00 to 10.0) so as to make it easy to adjust
the lens iris and select an ND filter.

Fig.3 Response frequency of the output
voltage when a spot light is moved
right and left repeatedly while it is
being applied to the sensitive area.
The rise time is the period of time required for the output voltage to rise from 10%
to 90% of its full level.
The fall time is the period required for the output voltage to return from 90% to 10%.
OPTIMUM INPUT LASER POWER
When light with the value on the table at the left is input, "8" appears on the
display indicating the volume of incident light. If strong laser light is used, an
ND filter or similar means should be used to reduce the volume of laser light
to the optimum volume before beginning measurement.
