Evident BFMX-MET Industrial Brightfield Darkfield Mix

Description

Built for multi-contrast metallographic failure analysis, the Evident BFMX-MET Industrial Brightfield Darkfield Mix delivers 50x to 1000x optical-digital magnification across an infinity-corrected UIS2 optical path. A cooled 2.35MP CMOS camera captures high-resolution digital streams. Dedicated brightfield and darkfield objectives isolate micro-fractures with high contrast, though dense opaque specimens require precise coaxial stage leveling.

A 14.2 kg industrial aluminum stand houses a quintuple BD revolving nosepiece with 5x, 10x, 20x, 50x, and 100x plan metallurgical objectives and a vertical LED illuminator supporting brightfield, darkfield, and MIX modes. The ceramic-coated stage measures 180 by 150 mm with 100 by 100 mm XY travel. Coaxial focus provides 1-micron fine tracking, paired with a dedicated digital camera dock and electronic current-regulated power box.

Key Features of Evident BFMX-MET Industrial Brightfield Darkfield Mix

Semiconductor cleanrooms, aerospace metallurgical laboratories, and micro-electronics failure analysis teams rely on this modular opto-digital system to detect fine surface defects. The specialized MIX lighting combines brightfield surface color with darkfield directional edge contrast, revealing micro-cracks and wafer scratches in a single live view.

UIS2 BD Objective Physics & MIX Contrast Lighting

Infinity-corrected UIS2 BD metallurgical plan objectives feature dual-path illumination rings, routing incident light through an outer annular channel for darkfield inspection and through the core lens for brightfield analysis. The directional MIX mode balances both illumination channels simultaneously, highlighting sub-micron polishing scratches and grain boundaries on reflective silicon wafers without wash-out.

Heavy Industrial Stage & Coaxial Gearing

Translating samples across an oversized 100 by 100 mm mechanical range, the ceramic-coated stage accommodates large circuit boards and metallurgical mounts with smooth, repeatable XY movement. Coaxial focus knobs operate with 1-micron fine sensitivity, enabling operators to measure step heights and fracture depths with dependable precision.

• Ceramic stage surface withstands years of heavy metal specimen friction without scratching
• Peltier-cooled CMOS camera sensor eliminates thermal noise during high-gain darkfield exposures
• Coaxial focus mechanism features an adjustable upper limit stop to safeguard front lens elements
