PSD
One-dimensional PSD
S3979, S3931, S3932, S1352, S3270
3 to 37 mm resistance length PSD for precision distance measurement
Hamamatsu provides various types of one-dimensional PSD (Position Sensitive Detector) designed for precision distance measurement such as
displacement meters. S3979 has a 1 × 3 mm active area sealed in a TO-5 package. S3931 and S3932 have an active area of 1 × 6 mm and 1 ×
12 mm respectively, and are mounted on a compact ceramic package with a transparent resin window. Variant types (S3931-01, S3932-01) with
a visible-cut resin window are also available. S1352 and S3270 offer an active area longer than 30 mm, allowing position detection at a long
distance.
S3270 has a visible-cut resin window, and S3270-01 with a transparent resin window is also available.

*1: K: borosilicate glass, R: clear resin coating, R
*2: Works with microscopic spot light detection.
*3: A range of 75 % of that from the center of the photosensitive surface to the edge.
*4: The upper limit of linearity of photocurrent in response to the quantity of light is defined as the point where the linearity
deviates by 10 %.
*5: Position resolution
This is the minimum detectable light spot displacement. The detection limit is indicated by the distance on the photosensitive
surface. The numerical value of the resolution of a position sensor using a PSD is proportional to both the length of the PSD
and the noise of the measuring system (resolution deteriorates) and inversely proportional to the photocurrent (incident
energy) of the PSD (resolution improves).
