Silicon photodiode
Hamamatsu Photonics

Photodiodes are semiconductors that generate a current or voltage when illuminated by light. They have no internal gain but can operate at much higher light levels than other detectors. Silicon photodiodes are suitable for precision photometry, making them useful in medical instrumentation, analytical instruments, semiconductor tools and industrial measurement systems.

Hamamatsu's silicon photodiodes have low capacitance and dark current, which reduces noise and increases speed. They cover a broad spectral range from the near infrared to vacuum ultraviolet light. Our ultraviolet photodiodes resist degradation in performance that results from continuous exposure to ultraviolet light. Silicon photodiodes are available in various active area sizes and in various packages (metal, ceramic, and plastic). We also welcome enquiries for custom-designed photodiodes to meet special needs.
