OC-1100 Optical Counter

OC-1100 is a high-sensitivity optical detector for oscilloscope-based measurements, providing clear visualization of optical signals on the measurement system display. The instrument combines high sensitivity, wide frequency capability, very low APD photodetector noise, and frequency counter functionality. The optical counter is housed in a compact and robust enclosure and features analog and USB outputs, an external clock input, and a power connector.

The analog output can be used for signal monitoring, for example with an external spectrum analyzer. The instrument is supplied with a power supply, USB cable, and PC software. The software enables automatic measurement of frequency deviations with averaging times from 100 µs to 1000 s, display or storage of results, and Allan deviation calculation, making the OC-1100 an efficient tool for testing laser frequency stability. The device is primarily intended for scientific and university laboratories.
