Diodes with Built-In Shut-Off Circuitry for Eye-Safe Applications

UK59-0480

The new “A4” series of compact APC laser diodes offers additional protective functionality for applications in which an eye-safe source of radiation is required. The “automatic power control” (APC) will shut down the laser once a specific operating current is exceeded.

The A4 laser diodes are insensitive to electrostatic discharges of up to 10 kV and a stable output power is guaranteed for supply voltages of 2.5 to 6 VDC. As was the case for the device’s predecessor, the APC is located at an ASIC on the same chip as the photodiode and the emitting laser diode, and is integrated in compact TO housings (3.3 mm or 5.6 mm). Diodes from this series are available at wavelengths between 635 nm and 850 nm and lend themselves well to applications in highprecision measurement.
