High-speed photodiodes (S5973 series: 1.5 GHz)
S5971, S5972 and S5973 series are high-speed Si PIN photodiodes designed for visible to near infrared light detection. These photodiodes
provide wideband characteristics at a low bias, making them suitable for optical communications and other high-speed photometry. S5973 series
includes a mini-lens type (S5973-01) that can be efficiently coupled to an optical fiber and a violet sensitivity enhanced type (S5973-02) ideal for
violet laser detection.
