Evident BX53-MET Metallurgical Brightfield Darkfield

Description

Engineered for multi-mode semiconductor wafer and alloy defect screening, the Evident BX53-MET Metallurgical Brightfield Darkfield delivers 50x to 500x incident magnification across an infinity-corrected UIS2 optical path. Widefield 10x eyepieces provide a 22mm field number. The specialized BD optical train resolves micro-cracks with high contrast, though dense opaque specimens require precise stage leveling.

A heavy 15.4 kg cast-aluminum stand houses a coded quintuple BD nosepiece with four MPlan FL N objectives, an incident white LED illuminator with a MIX slider, and Smart ILS brightness management. The ceramic-coated stage measures 240 by 180 mm with 76 by 52 mm right-hand XY travel. Coaxial focus provides 1-micron fine graduations with a torque lock, paired with a 30-degree inclined trinocular head offering 50mm to 76mm interpupillary spacing and a three-way light split.

Key Features of Evident BX53-MET Metallurgical Brightfield Darkfield

Semiconductor quality engineers and failure analysis metallurgists select this flagship research frame to identify surface anomalies across reflective components. The coded nosepiece links directly with software to recall calibrated scale bars automatically, while the MIX illumination slider combines directional darkfield shadows with brightfield color fidelity.

• Heavy-duty coaxial coarse and fine focus drive with 1-micron fine graduations and torque lock

UIS2 BD Objective Physics & MIX Contrast Lighting

UIS2 MPlan FL N BD objectives feature dual concentric illumination channels, directing incident light down the core lens for brightfield observation while projecting ring light through an outer darkfield mirror jacket. The motorized MIX slider blends brightfield surface reflectivity with directional darkfield grazing light, illuminating subtle wafer fractures and sub-micron polishing scratches that wash out under flat coaxial beams.

Ceramic Stage Stability & Fine Gearing Mechanics

Low-positioned right-hand coaxial controls allow your forearm to remain resting flat on the table while navigating the 76 by 52 mm stage stroke. The oversized ceramic stage plate resists scratching from rough metal castings, and the coaxial focus assembly tracks through 1-micron fine increments with an adjustable torque lock to prevent stage creep under heavy sample holders.

• Ceramic-coated stage sheet provides lifelong protection against specimen abrasion and etching fluids
• Three-position prism selector routes 100 percent of light to eyepieces, camera port, or an 80:20 split
• Coded nosepiece synchronizes objective magnification with imaging software for instant measurement calibration
