Power Meter for Blue/Green Lasers

Name: Power Meter for Blue/Green Lasers
Brand: MKS Ophir, Light & Measurement

In the automotive industry, heat conduction welding with blue and green lasers is increasingly the first choice for battery welding and connecting small copper parts in electrical components. The Ophir Helios Plus power meter measures high power industrial lasers of up to 12 kW and, for increased flexibility, provides an expanded choice of wavelengths: 450-550 nm (blue/green) and 900-1100 nm (infrared). The Helios Plus power meter is compact, requires no water cooling, and provides a high damage threshold. PROFINET, Ethernet/IP, and RS232 communication options make it easy to integrate into manufacturing networks. Once integrated into the production control system, fully automated measurements can be made.

The Helios Plus industrial power meter measures high power solid state lasers – such as diode, fiber, and Nd:YAG lasers – with powers from 100 W to 12 kW and energies from 10 J to 10 kJ. The system operates by measuring the power, energy, and exposure time of a short 0.3 to several seconds pulse and then calculating power. By keeping the pulse energy under 10 kJ, there is no need for water or fan cooling. This results in a convenient, compact design.

The Helios Plus power meter has a high damage threshold of over 6kW/cm2, a fast 2s response time, and short 10s wait between pulse measurements. The Helios Plus laser power meter is housed in a dust-resistant industrial enclosure to keep the power meter clean and in good working order, even under harsh factory conditions. The sensor’s cover can be opened and closed remotely, protecting the optics and electronics when not in use. Two communications options are provided: PROFINET and RS232, or EtherNet/IP and RS232.

The Helios Plus power meter comes with a simple PC application and command set for easy integration into the customer's system.
