Large screen overview

Status screens

The main CALM (Control And Laser Monitoring) screen can be set to show the following example of a laser laboratory installation indicating which areas are safe and which areas are not to be entered.

Also, minimal information about the laser is shown – i.e. wavelength, power and mode of operation

Remote control and monitoring can be carried out on a main screen.

It can also be seen on the ICS Buddy, which is a portable laser safety interlock controller.
