Photodiode PR5030

Application Notes

CHANNEL SEPARATION

A perpendicular crossover of a light beam be-

tween photodiodes C1 and C2 is illustrated. In-

crements of 10 µm were performed using red

light with a diameter of 50 µm. The position of

0 µm is related to the center of the metal line

between both photodiodes. The photocurrent

was measured with zero applied voltage.

Considering a gap between the photodiodes of

20 µm, the observed behavior is consistent

with a sharp channel separation.

MOVING APERTURE

By shining light on aperture, the passing light

can be detected. Due to the geometry of the

photodiodes, the position of the aperture can

be detected as given in the diagram.

MOVING OBJECT

The location of an object moving above the

triangular shaped photodiodes can be detected.

According to the position of the edge, at C1 and

C2 the following signals are received.
