Description
Typical Responsivity for J16Si Series
Two color detectors consist of a high
1.0
performance Silicon detector mounted in
a "sandwich" configuration over another
Silicon
Germanium
detector.
The silicon photodiode responds to
radiation from 400 nm to 1000 nm.
Longer wavelengths pass through the
silicon and are detected by the detector
underneath.
J16Si Series detectors are ideal for
optic power measurements that need to

differentiate between 800nm and either
1300nm or 1550nm. They are also useful
for two-color temperature measurements
from 500°C to 2000°C.

The Si and Ge elements each require a
preamplifier. A Teledyne Judson model
PA-7 is recommended for each element.

1. Qλ(TGB) is photon flux per unit wavelength interval from greybody source.
2. Ratio S1/S2 can be used to determine greybody temperature TGB
regardless of emissivity or absolute signal levels.
