C7339

• Quick Response
   The response time of less than 20ms enables accurate measurement 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 fluctuations 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 insensitive 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 C7339 Position Sensor is an opto-electric positionsensing unit which measures the position of a single point of light spot-focused onto the sensor head.

The use of hybrid circuitry C7339 allows for a compact, lightweight 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 operation. 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 recorder.

The C7339 does not possess a background-light cancellation 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.
