Technical content

(For Laser Beam Alignment) 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. 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.

FEATURES

  • 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 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.

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%. 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. 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.
