Ensuring beam quality in automated industrial laser materials processing poses many challenges for measurement technology. MKS addressed these challenges by developing Ophir BeamWatch Integrated. This measurement system is based on non-contact measurement technology Ophir developed with the BeamWatch system, but comes with additional functions that have been enhanced for the needs of the digital process chain: Ophir BeamWatch Integrated laser measurement systems add a robust housing and include either Profinet, Ethernet/IP, or CC-Link interfaces. All data collected is directly sent to the network and can be analyzed and stored, displayed in individually configurable reports, and displayed on a machine interface in a special configuration for operators. For the first time, it is possible to measure focus shift and focus spot size in real-time, with the full measurement ready in less than one minute. An integrated power meter measures the overall power and serves as a beam dump.
All these features make the system attractive, especially for new cutting and welding applications. Recently, a new BeamWatch Integrated 500 with a longer distance was released (see fig. 1) - 500 mm instead of 250 mm between the BeamWatch optics and the power meter. This version is designed for use with single mode lasers with a low divergence, as found in battery welding, for example. All in all, there are six different models of the BeamWatch Integrated system available today, each serving different needs.
