Introducing 3rd Generation

Available Scanning Modes for MIRA

Resolution Depth Field Wide Field Channeling

Wide Field Optics™! Unique Tescan four-lens column design offering a varity of

working a displaying modes! IML - Intermediate lens for beam aperture optimization! No physical final aperture; ALL electronically controlled

Modern Optics!Minimized distortion effect!Ultra-fast scanning rates down to 20 ns/pixel!Automated alignment- NO need of mechanical adjustment

SEM Column

In-Flight Beam Tracing™! Newly implemented for high precision computation of optimal

parameters

! Probe Current and Probe Diameter Easily Specified by User

!SEM Can Capture 16k x 16k Images (Competitors Charge over $24k for this option; standard for Tescan)!These extremely large images can then tiled into massively high-resolution image (Over a Gigapixel)!Area of interest can be clicked; user can zoom in with full resolution.!It‘s like Google Earth for the SEM
