Product Introduction

Description

Variable beam expanders are ideal for systems in which different magnifications and precise control of laser beam pergence are required. We offer Galilean type variable beam expanders with high LIDT AR coatings that minimize ghost reflections. Our variable beam expanders allows to separately adjust magnification and pergence. Two main standard products change magnification in the range of 1x-4x and 2x-8x.

Features

• High pointing stability (<1 mrad)

• Inpidual reports of beam ellipticity, M2 and pointing stability parameters

• Mounting adapters at the input, output and middle are available on request

• Extended lifetime and LIDT for UV applications
