The first step in defining a measurement system is to choose the detector needed for your specific application.
The next step is the meter selection:
4π is a small, battery operated meter designed for a laser engineer who spends much of his time in the lab and needs multi-function and sophisticated equipment for his qualitative measurements and laser set-up alignment.
PLUS -2 offers powerful analysis software and extends measurement capabilities when budget or environment constraints require a simpler monitoring system.
PC-Link mates with all Laser Point detectors and can be plugged in to any portable PC. Ideal for the service engineer who will need compact and low weight equipment when travelling. While having the ability to use different heads, e.g. for high and low powers.
The following at-a-glance table will help in your meter selection.
