Photodetectors
Packaged photodetectors based on PIN photodiodes for monitoring Q-switched and mode-locked pulsed lasers.
- Compact Integrated Package Complete ready-to-use solution in a compact package, including optional bias.
- Flexible Options Full range of detector materials and sizes, free-space or fiber-coupled, plus wall-plug option.
- Simple Operation Plug directly into 50 Ω coaxial input of oscilloscope or spectrum analyzer.
Complete Family of Photodetector Products
Three types of photodetectors to support all your laboratory and OEM needs. <10 GHz photodetectors for general use, >10 GHz devices for high repetition-rate applications, and amplified detectors including a transimpedance amplifier for low-energy pulses.
Don’t know which is the right product for you? We can help you choose.
 <10 GHz Photodetectors Monitor the pulse energy and/or pulse shape of your laser at speeds up to a few GHz, at wavelengths spanning the visible and near-IR with very low noise equivalent power (NEP). BNC output connector. |
Wide Wavelength Coverage - Choice of Si or InGaAs photodiodes. |
Optimized Detec or Sizes - Active area diameters from 100 µm to 4.6 mm. |
Integrated Internal Bias - Each photodetector includes a long-life lithium cell. |
 >10 GHz Photodetectors For very high-frequency applications include heterodyne signal detection and fast time-domain measurements. SMA output connector. |
Ultra-high Frequency Response -Bandwidths as high as >22 GHz. |
Input Options - Choice of single- or multi-mode fiber, or free-space inputs. |
Broad Wavelength Options - Responsive from 500 nm to >2000 nm. |
 Amplified Photodetectors Integrated transimpedance amplifier combines high gain for low input power < 1 mW together with high bandwidth – up to 10 GHz. |
High Conversion Gain - As high as 3.25 V/mW. |
Input Flexibility - Fiber-coupled or free-space, with half-angle acceptance up to 20°. |
Compact Design - Small footprint integrates easily into your system. |
