KR-1W

INTRODUCTION

Thank you for purchasing the TOPCON Wave-front Analyzer KR-1W.

This instrument has the following features:

• The refractive power of the eye, the curvature radius of the cornea and the pupil diameter can be determined by simple operations.

• By displaying the Hartmann image and Mire image, wavefront aberration measurement of the eye can be done.

•

Auto alignment and auto start functions enabling quick measurement under best conditions

This text outlines the TOPCON Wave-front Analyzer KR-1W and describes basic operations, troubleshooting, checking, maintenance and cleaning. To encourage the safe, efficient use of this instrument, carefully read "DISPLAYS FOR SAFE USE" and "GENERAL SAFETY INFORMATION."
