Product Description

IntroductionEquipped with varisized wafer holders (including 6/8 inches), BS-4050 is professionally applied for wafer and flat panel display detection. More comfortable, flexible and quicker operation is available with upgraded ergonomics design.
Features
1. Multi optional splitting ratioWith broad beam image system, maximum field of view of BS-4050 reaches to 26.5mm. Trinocular head with two optional splitting ratios of 100:0 or 0:100, 100% image outputs from eyepieces or camera. Trinocular head with three optional splitting ratios of 100:0 or 20:80 or 0:100, double-way image output of 20% from eyepieces and 80% from camera is achievable. The erect gemel trinocular head, same direction and same moving direction for objective and image, easy to view and operate.2. Stable frame
All metal frame with the characteristics of low center, high rigidity and stability for professional industrial inspection, ensures to present a stable and clear image.
3. High-performance nosepiece
High-performance nosepiece with precision bearing, is available for light and handy operation, precision resetting, controllable concentricity.
