Frequently asked questions
What is the founding family's role in Hamamatsu Photonics?
The Hiruma family founded the company in 1953 and retains operational control. Akira Hiruma, grandson of founder Teruo Hiruma, serves as president and CEO. The family's stake ensures long-term R&D commitment rather than quarterly earnings pressure.
What makes Hamamatsu's photomultiplier tubes unique?
Hamamatsu's photomultiplier tubes detect single photons across wavelengths from ultraviolet to near-infrared, achieving quantum efficiencies above 40%. The company integrates in-house scintillator growth and glass fabrication, enabling custom designs for CERN experiments and medical PET scanners that competitors cannot replicate.
What industries rely on Hamamatsu's technology?
High-energy physics (CERN, Fermilab), medical imaging (PET, CT, fluorescence microscopy), semiconductor inspection (wafer defect detection), environmental monitoring (fluorescence analysis), and defense (night vision, laser detection).
How does Hamamatsu invest in R&D?
The company allocates approximately 8% of annual revenue to R&D (per company reports, 2024). Its Hamamatsu-based central research lab collaborates with universities and national labs. Recent focuses include quantum photonics, lidar for autonomous vehicles, and ultra-fast cameras.
What competition does Hamamatsu face in the photonics market?
Competitors include PerkinElmer, Excelitas Technologies, and Onsemi in related sensor categories. For photomultiplier tubes specifically, Hamamatsu holds over 60% global market share; no single company matches its sensitivity range and custom manufacturing capability.
