Terahertz (THz) sensors

THz sensors are sensitive to the terahertz wavelength region, which has attracted attention in recent years. They utilize metasurface technology to convert terahertz waves into electrons.

The R17201-01 is a photomultiplier tube (PMT) that utilizes metasurface technology for THz wave-to-electron conversion and has sensitivity in the THz wave region. It utilizes field electron emission technology, and the signal current changes non-linearly in accordance with the electric field intensity of the incident THz wave, making it possible to enhance and detect micro-changes in THz waves that had been difficult to detect with conventional detectors.

The H17362 is a photomultiplier tube (PMT) module that utilizes metasurface technology for THz wave-to-electron conversion and has sensitivity in the THz wave region. This THz PMT module incorporates a THz PMT, driver circuit, and high-voltage power supply into a compact housing. It can be operated by simply connecting it to a PC via USB. It comes with an attachment that can be easily installed on an optical table and a C-mount adapter for attaching optical components. Easy to handle even for those who are new to photomultiplier tubes.

The C17198 is an imaging device that utilizes metasurface technology for THz wave-to-electron conversion and has sensitivity in the THz wave region. It is useful as "THz beam visualizer" for laboratory use, where it can visualize and observe invisible THz waves at hand. In addition, it is capable of high-speed imaging at up to 1000 fps, making it possible to image high-speed phenomena that had been difficult to capture with conventional thermal THz cameras.
