The C4258 series of picosecond photodetectors consists of pho-
todetectors featuring a light detector, a high-frequency circuit,and
a battery integrated in a single unit, as well as fast response. Opti-
cal phenomena in the picosecond region can be measured sim-
plyby irradiating the unit with an optical beam and connecting the
output to an external oscilloscope.
A high-speed MSM photodiode is used as the detector, enabling
a fast rise time , a large active area. For this reason, the C4258 is
ideal for pulse waveform observation of picosecond lasers such
as Ti: sapphire / YAG lasers, and semiconductor lasers for
DVDs and optical communications. In addition, by combining it
with a short-pulselight source, the C4258 can be used in applica-
tions such as measuring the transmission characteristics of opt-
ical fibers.
Four models are available. This lets the user select which ever
model is optimum for the wavelength of the pulse being meas-
ured.
