Spectroscopy Detectors - InAs Series

High performance INAS series NIR detectors with a  spectral range from 1 to 3.8 µm

DInAs 3800: Built-in import,   Room temperature detectors

DInAs 3800-TE: Built-in import, TE cooling detectors

Before connecting to the signal processors (i.e. oscilloscope or lock-in amplifier, )  the IV Tranc-impedance Amplifier (ZAMP) is recommended to be connected as a preamp and which can be the input current signal.

The user can connect the detectors to the signal processors directly but in order to improve the detection sensitivity, the IV Tranc-impedance Amplifier is recommended

When used with DCS data acquisition system, the IV Tranc-impedance Amplifier is also recommended in order to improve the detection sensitivity.

If the DInAs 3800 and DInAs 3800-TE detectors are used with the DCS 300PA data acquisition system, as signal amplifier has been integrated in the DCS 300PA dual-channel; it does not meet to match a preamplifier.

In the TE cooled mode, DInAs 3800-TE detectors must work with Temperature controller (ZTC) for cooling control.
