PRODUCT DESCRIPTION

PRODUCT INTRODUCTION 

Coherent PowerMax-USB sensors provide plug-and-play laser power measurement directly on a PC without the need for additional electronic instrumentation. The circuitry and USB connector have been adapted into a ‘PowerMax-USB’ cable that can be integrated to most Coherent power sensors providing accurate power measurements of all types of CW and pulsed sources from the UV to Far IR.

FEATURES 

USB 2.0 port 

PowerMax USB provides direct USB 2.0 connection to PC. Power provided via USB connection. Software and driver is
compatible with Microsoft XP, Vista (32-bit and 64-bit), and Windows 7 (32-bit and 64-bit)

Instrumentation platform 

Instrumentation platform is compatible with thermopiles and optical sensors and can be adapted to most power sensors that Coherent manufactures.

High resolution 24-bit A/D converter 

High resolution 24-bit A/D converter supports four digits of resolution and measurement accuracy equivalent to that found in Coherent’s LabMax meters.

Correctly determine the wavelengths

Sensors include spectral compensation for accurate use at wavelengths that differ from the calibration wavelength. Each device receives a unique spectral compensation curve specific to the absorption of its specific element, as well as transmission characterization of any associated optics.

The algorithm increases the reaction speed of the heat detector

Thermopile sensors include a speed-up algorithm that speeds up the natural response of the thermopile detector without overshoot.
