Manufacturer Introduction

Hamamatsu Photonics K.K is a company specialized in the developing, manufacturing and marketing of the opto-semiconductors, photosensitive electron tubes, LED/LD light sources, cameras/image measurement, optical measurement, X-ray, etc. The company was established in 1953 and headquartered in Shizuoka, Japan. The company has formed branch offices in Germany, Netherlands, Danish, Poland, France, Switzerland, Belgium and Spain to establish a global distribution sales network. 

Hamamatsu Photonics K.K has developed a wide range of products. The opto-semiconductors cover photodiodes, photo IC, image sensors, infrared detectors, LED, X-ray flat panel sensors, optical communication devices and some related products. The photosensitive electron tubes include photomultiplier tubes (PMT), phototubes, electron multiplier tubes, flame sensors (UV TRON), MCP(Microchannel Plate), image intensifiers(I.I.), photon detection unit, UV power meter, UV power meter for photocatalyst and optical blocks. The LED/laser/light source mainly include LED, laser diodes, xenon flash lamps, spot light sources and so on. The cameras/ image measurement include industrial cameras, TDI cameras, high sensitivity models, etc. The products are widely used in life science, medical, optical communications, spectroscopy, multiband plasma-process monitor, FPD measurement and product support, semiconductor failure analysis and product support and so on.

At present, CCDs in the field of scientific imaging can be divided into three categories: one is interline transfer CCD (IG-CCD), and the other is
A full-frame transfer CCD (FFT) is used, and the last one is a frame transfer CCD (FT-CCD).
Based on the development of chip technology, there are many types of CCD cameras. The quantum efficiency of ILCCD is as high as 70%, the quantum efficiency of BT is as high as 90%, and the detection limit is close to the theoretical value. The noise of the CCD now determines the strength of the signal detection. The dark current and the readout noise are the two main factors that produce noise. They decided on the performance of the CCD and its application in low light.
In view of the innovation of CCD technology, various high-sensitivity and low-noise CCDs are achievable. However, the readout noise of the CCD is still the main factor limiting the detection of weak signals. The signal below the readout noise can be detected by signal integration of the CCD chip. After a period of signal accumulation, the signal becomes larger than the readout noise. In addition, there are other image enhancement techniques for signal amplification, such as microchannel plates (MCP) and direct electron bombardment electronbombardment. The direct CCD electron multiplication mechanism has been in use for many years, but the core issue surrounding this technology is the electron multiplication process on the chip, which is the main problem limiting EM CCD applications. With the latest chip electron multiplication technology, EMCCD is increasingly used in ultra-weak photo bio-imaging.
Hamamatsu Photonics K.K. uses the latest cooling and CCD design techniques for the ImagEM EM-CCD. The ImagEM camera was produced after years of experimentation and years of experience, including deep cooling, high vacuum and low noise CCD technology. It provides optimized signal and noise for a wide range of applications. The same digital camera, which now captures low-brightness and high-brightness images, wide dynamic range images and single-photon binary images, long-time integrated exposure and high frame rate images, which provides a very high density over a wide range of wavelengths Quantum efficiency. The following features almost all confirm that this new camera can work on any application.
◆-90 °C vacuum packaging deep cooling
◆gain stability / temperature stability
◆ ImagEM has EM-CCD read mode and normal CCD read mode.
◆Multiple pixel clock selection
◆Photon imaging mode (patent pending)
◆ Real-time image processing
◆External trigger / synchronous read trigger
◆Programmable trigger signal output
◆Multiple camera head capabilities

Hamamatsu is product portfolio consists of Photomultiplier tubes, sensors, optoelectronic semiconductors, light sources, laser products, light detection science and medical instruments, etc..
