Ideal for both observation and digital imaging applications.

Large 12.5:1 Zoom Range

The precision zoom system offers continuous magnification from 0.63× to 8× with positive click-stops at popular magnifications for repeatable inspection work.

Combined with the standard optics this provides:

• 6.3× – 80× total magnification

Optional objectives and eyepieces allow magnifications up to 320×.

Built-In Aperture Diaphragm

An integrated aperture diaphragm allows users to optimise:

• Depth of field
• Image contrast
• Resolution
• Brightness

This is particularly beneficial when inspecting three-dimensional specimens.

Precision Focusing

Both models feature a robust integrated focusing system with:

• Coaxial coarse and fine focus controls
• 50 mm focusing range
• Fine focus accuracy of 0.002 mm

Ideal for demanding laboratory and industrial inspection tasks.
