Technical details and manufacturing context for Laser Emitter

Definition
The laser emitter is a critical component of the Laser Safety Scanner that produces a coherent, focused beam of light used to create a protective detection field. It works in conjunction with a receiver to monitor for intrusions into hazardous areas by detecting beam interruptions. The emitter is typically based on a semiconductor laser diode, with a wavelength of 905 nm (IEC 60825-1 Class 1 or 1M), and an output power of 1–10 mW. The beam divergence is 0.1–0.5 mrad, and the pulse duration is 5–20 ns with a repetition rate of 10–100 kHz. The device operates on a 24 V DC supply (±10%) and consumes 2–5 W. It is designed for an operating temperature range of -10 to 50 °C and storage from -20 to 70 °C, with relative humidity 10–95% non-condensing. The housing provides ingress protection of IP65–IP67. The emitter is compact, with dimensions of 30×20×15 mm and a weight of 50–200 g. Materials include semiconductor (GaAs/GaAlAs), optical glass, and an aluminum housing. This component is intended for integration into safety scanners; all values are typical reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier.
Working Principle
The laser emitter generates light through stimulated emission, typically using a semiconductor laser diode. Electrical current excites the active medium, causing it to emit photons that are amplified and collimated into a narrow, directional beam. This beam is precisely aimed at a corresponding receiver to establish a continuous detection line. In a safety scanner, the emitter produces short pulses (5–20 ns) at a high repetition rate (10–100 kHz) to enable time-of-flight measurements and to create a protective field. The beam divergence is kept low (0.1–0.5 mrad) to maintain accuracy over distance. The emitter is designed to be eye-safe under normal use (Class 1 or 1M per IEC 60825-1).

Frequently Asked Questions

What is the typical wavelength of this laser emitter?

The typical wavelength is 905 nm, as listed in the reference parameters. This is a common wavelength for safety scanners and is classified as eye-safe under IEC 60825-1 Class 1 or 1M. Always confirm the exact wavelength for your specific model.

What are the electrical requirements?

The emitter requires a 24 V DC supply with a tolerance of ±10%. Power consumption is typically 2–5 W, including drive electronics. Ensure your power supply meets these requirements and consider inrush current and stability.

What environmental conditions can it withstand?

The operating temperature range is -10 to 50 °C, and storage temperature is -20 to 70 °C. Relative humidity should be 10–95% non-condensing. The housing offers ingress protection of IP65–IP67, making it dust-tight and water-resistant. Verify these ratings for your application.

How does the emitter contribute to safety scanning?

The emitter generates a pulsed laser beam that is directed toward a receiver. If an object interrupts the beam, the system detects the intrusion and can trigger safety measures. The short pulses and high repetition rate enable precise time-of-flight measurements, enhancing detection accuracy.
