Key Features
- 12.5X zoom ratio with 0.58X-7.5X optical magnification.
- Integrated coaxial episcopic illumination structure.
- Infinity-corrected parallel illumination for reduced shadows.
- Uniform illumination for improved magnified image quality.
- High resolution, low distortion and high numerical aperture.
- Resolution down to 3.05 μm at higher magnifications.
- Stable 77.4 ± 2 mm working distance.
- Supports industrial camera sensors up to 2/3 inch.
- Standard C-Mount camera interface.
Coaxial Illumination Advantages
Conventional side illumination may produce shadows and uneven reflections when inspecting flat or reflective surfaces. The coaxial illumination structure directs light along the optical axis and toward the inspection surface, providing more uniform illumination.
This lighting method is particularly suitable for inspecting semiconductor surfaces, PCB pads, metal components, connectors, printed characters and other reflective or low-contrast features.
