Hamamatsu Photonics releases a new highly sensitive photon-counting head with lens, ideal for blood testing with compact instruments

  • Hamamatsu Photonics K.K.

Hamamatsu Photonics has developed a new photon-counting head with lens by applying our well-known capabilities in photomultiplier tubes (PMT) and optical design technology. The photon counting head1, ‘H10682-110W’, is integrated with a newly designed condenser lens offering high light-collecting efficiency while using a thin profile. Its sensitivity is 5 times superior to our currently available products, though still maintaining the same small size.

The H10682-110W can be installed into compact in-vitro diagnostic instruments to increase their sensitivity. This reduces the amount of blood and other specimens that need to be collected from patients while still providing the same accuracy, making testing more comfortable. Another benefit is the shorter measurement time which will lower the workload of medical staff.

Sales of the H10682-110W will start on Wednesday, November 1 this year for domestic and overseas manufacturers of compact in-vitro diagnostic instruments and other measurement devices utilizing low-level light. The H10682-110W will also be on exhibit at “PHOTON FAIR 2023” which is an all-inclusive Hamamatsu Photonics exhibition showing off our advanced technologies and products from Thursday, November 16 at Act City Hamamatsu.


1:  A high-sensitivity sensor head that contains a PMT along with a high-voltage power supply circuit needed for PMT operation, and a photon counting circuit for measuring the number of photons (light particles). It offers excellent signal-to-noise ratio and stability for low-level-light measurements.
