Acuity Laser Announces New AS2100 Accurate Distance Sensor Posted in: Updates

Acuity Laser is pleased to announce the release of a new product, the AS2100 Accurate Distance Sensor. Coming from the company’s long range sensor group, the AS2100 is an improved replacement product for the now retired AR2000.

“For many years the AR2000 was a great choice for distance measurement in difficult environments,” said Nick Catalano, Acuity’s General Manager. “Now we have an even stronger option in the AS2100.”

A highly accurate laser distance sensor, the AS2100 is designed to work well outdoors, in bright lights, and even on difficult hot or dark surfaces. It provides superior accuracy at long range. It can measure natural targets up to 100m away and Acuity reflective targets up to 500m away with an accuracy of +/- 1 mm.

The AS2100 has a Class 2, red, visible laser diode for simple aiming and setup. The spot size starts at 0.15 inches and grows to only about 2 inches at distances of 100 meters. Larger targets may be necessary at longer distances.

With a maximum measurement frequency of 250Hz, these sensors excel in distance measurement applications with bright, dark, hot, and textured surfaces.


Due to the product’s high performing specs and ability to provide accurate measurements on difficult targets, it’s the perfect laser for a wide variety of applications and industries, including:

  • Metal production applications, for example controlling fill level for steel and iron, cut to length applications for steel and aluminum, and dimensional measurements of hot materials.
  • Transportation industry applications, for example, positional measurements during materials handling processes, crane positioning, trolleys and vertical lifts positioning, and flood gate position measurements in dam operations.
  • Process control applications, such as cut to length measurements (steel & lumber industries), diameter and width measurements of rolls (paper & steel), length/width positioning measurements for sorting applications, and more.
  • Fill level measurement applications, such as silo level measurements & controlling the filling and pouring of steel and iron.

“We hope by including the AS2100 in our catalog,” Catalano said, “we can provide new and existing customers with the best distance sensor options they need for their measurement challenges.”
