Parameters
Brand: Hamamatsu
Model: S5973-01
Operating Principle: Image Sensing

1. Basic Product Introduction
The S5973-01 from Hamamatsu is a mini-lens type silicon PIN photodetector, mainly designed for high-speed optical signal acquisition in the visible to near-infrared range.
It has a built-in micro condenser lens that allows direct efficient coupling with optical fibers, eliminating the need for additional optical focusing structures.
It only requires a low reverse voltage of 3.3V to achieve full bandwidth performance, and its wide spectral response makes it suitable for various detection scenarios.
The package is a standard TO-18 metal through-hole, making it easy to solder and assemble for industrial use.

2. Key Features
Ultra-high response speed
With a reverse bias Vᵣ=3.3V, the bandwidth can reach up to 1GHz, perfect for high-speed modulated optical signal reception; maximum reverse voltage tolerance is 20V.
Spectral Detection Range
Wavelength response is 320~1000nm, covering the UV end, all visible light, and near-infrared communication bands, with a peak response around 760nm.
Cost and Reliability
Mature for mass production and low procurement cost; fully metal-sealed package provides moisture and vibration resistance, ensuring long-term operational stability.
Optical Advantages
The top-integrated micro convex lens greatly improves fiber coupling efficiency, suitable for direct fiber-connected detection solutions.
