SID4-eSWIR

Introduction

HIGH RESOLUTION EXTENDED SWIR WAVE FRONT SENSOR


The SID4-eSWIR wave front sensor integrates PHASICS patented technology with a T2SL detector. Thanks to its high spatial resolution and great sensitivity, it offers accurate wave front measurement over the extended SWIR range from 1.0 to 2.35 µm
SID4-eSWIR is an innovative solution for testing SWIR sources and lenses used in optical communications, inspection instruments or night vision in military and surveillance devices. It provides both MTF and aberrations in one single shot measurement.
Applications: Free-space optical communication | Defense & Security | Aerospace

Introduction

COMPLETE BEAM CHARACTERIZATION | High resolution wavefront analysis software


The SID4 software package manages wavefront acquisition and analysis with one of our wavefront sensors. This software is entirely dedicated to laser beam analysis. It eases the use of the wavefront sensor (camera settings, acquisition modes, alignment helpers, automatic mask adjustment) and provides relevant tools for beam phase analysis: PSF, wavefront aberrations, laser beam parameters, beam profiles…
