Operating example
S1352, S3931 and S3932 (PSD made by Hamamatsu) can be
directly mounted on the board. To mount other types of 1-D
PSDs, use through holes on the board.

Measurement conditions
1. Light source: LED (
λ
p=900 nm)
2. Light spot:
φ
200 μm
3. PSD: S1352 (L=34 mm)
4. PSD photocurrent: 10 μA
5. Voltmeter: 195A (KEITHLEY)
6. Frequency bandwidth: 10 Hz
7. Constant voltage power supply: ±15 V, power supply capacity:
0.1 A or more, ripple voltage: 3 mVp-p or less
When measured under the above conditions, the following output
voltage amplitude and position resolution can be obtained.
· Output voltage amplitude: V
FS
=±10 V
· Position resolution:
l
=approx. 0.3 μm (calculated value)
