The Simmons Pro measures distance using a combination of two lasers

  1. One infrared (IR) laser
  2. One visible red laser.

IR Laser

The IR laser emits light at a 940nm wavelength which is invisible to the human eye but can be detected by the camera lens of your smartphone. This allows you to easily see where the measurement point is located on your smartphone’s screen.

Visible Red Laser

The second laser beam is emitted from the tip of the measuring probe, which is made out of plastic. It has a diameter of about 1mm.

The laser beams are reflected off the surface being measured and then return back to the sensor in the measuring head. The distance between the sensor and the surface is calculated based on the time it takes for the laser beams to travel back and forth.
