FieldMax II Laser Power & Energy Meter

The laser power meter that defines versatility

Versatile is the word that best sums up FieldMax II. Small enough for field service, but smart and capable for use in the lab, FieldMax is available in three models: FieldMax II TO is compatible with thermal and photodiode heads; FieldMax II P works with pyroelectric sensors; and FieldMax II TOP can be used with thermal, photodiode and pyroelectric sensors for all-round flexibility. A USB interface, LabView® drivers and ability to measure every pulse at up to 300Hz complete the picture.

A large, easily read LCD display makes using FieldMax a pleasure, combining a bold digital display of the laser power or energy and an analogue-like bar graph for laser tuning and alignment. An adjustable kick-stand makes FieldMax more easily viewed. Hooking FieldMax up to your computer couldn’t be easier; a USB interface and supplied application software allows you to control the meter from a PC and record test data. LabView® drivers and an ActiveX API make it straightforward for those wishing to write their own software to control FieldMax. FieldMax operates from an AC adaptor; a rechargeable battery pack is available as an option for those wishing to use FieldMax away from the laboratory.

The FieldMax II TO is available with selected sensors at reduced prices as part of Coherent's power meter value package programme.
