Our standard photodetectors are ideal for implementing quantum measurements such as characterizing squeezed light. They offer the lowest noise equivalant power and highest quantum efficiency of any commercially available detectors, at a highly competitive price. When ordering, first select one of the following photodiodes.
Once a photodiode is selected, we will integrate two of these into one of our balanced detectors. The table below gives the performance specifications of our balanced transimpedance amplifier.
| Parameter | Value | Unit | Notes |
|---|---|---|---|
| Gain | 10k | Ohms | |
| -3dB power bandwidth | 500 | MHz | Typical, depends on photodiode selection |
| Noise flatband | 1k - 300M | Hz | Typical, depends on photodiode selection |
| Minimum noise equivalant current | 2 | pA/rtHz | |
| Output voltage range | +/-5 | V | 50 Ohm load |
| Output impedance | 50 | Ohms |
