Optical micrometer with HTML5 interface is smartphone-compatible

Paul Boughton

The optoCONTROL 2520 high performance, self-contained optical laser micrometer from Micro-Epsilon has been upgraded with several new features that simplify user set up and configuration.

The optoCONTROL 2520 laser micrometer with integrated controller and Ethernet interface stands out due to its high precision, 46mm measuring range and a maximum transmitter/receiver distance of up to 2m. The web browser interface now runs on HTML5 instead of Java, which means improved stability and reliability.

With no additional installation software required and its web browser interface for configuration and set up, the optoCONTROL 2520 laser micrometer is now even easier to use. The laser micrometer now runs on HTML5 and can be operated from a smartphone. A measurement chart displays limit values. In addition, the system provides various averaging and filter methods, as well as statistical features. Up to eight segments can be measured and output simultaneously. The user can also switch the display from Metric (mm) to Imperial (inch) measurement units.

OptoCONTROL sensors measure the dimensions, edges or gaps on a target using the ThruBeam ‘shadow’ principle. The transmitter produces a parallel light curtain that is transmitted via a lens arrangement into the receiving unit. The beam is interrupted if there is an object in the light path. The CCD camera in the receiver unit measures the ‘target’ contour formed by the shadow and outputs this as a geometrical value. The target object can be in any position within the light curtain. The smallest detectable diameter of the target object is approximately 0.5mm, which means the system can be used to measure small gaps or objects such as IC pins and pin strips in electronics production. The sensor is also suitable for detecting large objects, performing large distance measurements, counting tasks and roundness measurement. Up to eight segments of the target can be measured and output simultaneously.

As well as having an extremely compact design, the optoCONTROL 2520 also offers high accuracy and a maximum transmitter to receiver gap of 2 metres, which, unlike any other micrometer currently on the market, allows the target to be positioned at any point in the gap.
