Pyroelectric detector SPY

The SPY is a vacuum-compatible, highly sensitive pyroelectric detector for the measurement of different radiation sources.
It provides the performance of the MPY-01 detector while being significantly smaller in size. It is also equipped with an external power supply, so that long measurement series are possible without changing batteries.

In the vacuum-compatible version, the supplied vacuum feed-through for power supply and a standard SMA feed-through (not included) allow easy integration into your vacuum measurement system.

The optical bandwidth of the detector element is extremely wide, so that it can be used as a terahertz detector and infrared detector but also in the visible and UV range. The specific applicability is only limited by the choice of the optical window. Different windows with different transmission bandwidths are available.
The signal output with SMA socket is adapted for the connection of a Lockin amplifier as well as for data acquisition cards and oscilloscopes.

Examples of use and help for integration into an existing measurement system can be found on this website under Tutorials.
