In the photosensor field, photomultiplier tubes (or PMT) are known to have particularly high sensitivity. PMT also have dozens of other advantages such as high-speed response time.
Electron multiplier tubes are also called electron multipliers or ion multipliers, and are used to detect electrons, ions, charged particles, vacuum ultraviolet rays, and soft X-rays, etc.
The UVtrons are UV sensors that utilize the photoelectric effect from metal and gas multiplication. These devices are sensitive only to UV light in a spectral range of 185 nm to 260 nm.
MCP is an electron multiplier that detects and multiplies electrons in two dimensions. MCP is also sensitive to ions, vacuum UV rays, X-rays and gamma rays and so can also be used as devices to detect their position and energy.
Image intensifiers produce high-contrast images even under dark conditions, and are used for night-time (surveillance) viewing as well as for scientific and technical research.
Photon Detection Units are photon counting units designed to make low-light measurements at single photon levels without a time-consuming measurement setup.
The C9536/H9535 series are UV power meters that directly measure UV light at specific wavelengths. The H9535 (sensor head) uses a UV sensor (phototube) that ensures stable UV measurement over a long period of operation and is calibrated in combination with the C9536 (controller) based on NIST standards.
The optical blocks are compact units that contain components such as bandpass filters and dichroic mirrors. They are designed for lowlight- level measurements that use PMT modules and high-sensitivity cameras.
