Compact, Low-Cost Optical Power Meters for Photonics Alignment Provide High Bandwidth |
|
| (Nanowerk News) The F-712.IRP1 and its two channel sibling, the F-712.IRP2, convert optical signals in the 600nm to 1700nm range with optical power from 230 picowatts to 1.3 milliwatts into an analog output voltage of 0.1V - 1.6V. In order to be useful for fast optical alignment systems, the output signal conversion is logarithmic and optical power changes can be detected and converted with a bandwidth of 6kHz. | |

Features & Advantages |
|
| The logarithmic output scaling is very important for fast scans and gradient search algorithms, because the signal strength can fluctuate by several orders of magnitude within a few milliseconds, considering the minute dimensions of modern fiber optical components, such as waveguides and arrays. | |
| The broad optical range from 600nm to 1700nm allows for usability in both the visible and infrared range without switching. | |
| A clever design of the optical input connector / socket interface eliminates the influence of the position of the optical fiber in the connector on the optical signal. | |
| Next to the affordability of the new power meters, the compact size of the single channel version (roughly only 4x3x2 inches) is another advantage. | |
