Meiji MA718 Super-Widefield 7.5× Eyepieces — Sold in Pairs
The Meiji MA718 Super-Widefield 7.5× eyepieces are designed for applications requiring increased magnification while preserving a wide, comfortable field of view. Compared to lower-power eyepieces, 7.5× eyepieces provide greater visual detail without the extreme narrowing of context associated with high-power oculars.
Sold as a matched pair, the MA718 eyepieces support balanced binocular viewing and are commonly selected for cleanroom inspection, electronics assembly, and medical device manufacturing where finer features must be evaluated without sacrificing operator comfort.
Published configuration
- Eyepiece type: Super-widefield
- Magnification: 7.5×
- Field of view: Widefield design (expanded viewing area)
- Viewing style: Binocular (matched pair)
- Compatibility: Meiji stereo microscope systems
- Quantity: Sold as one pair (two eyepieces)

Why choose 7.5× eyepieces?
Seven-and-a-half-power eyepieces increase effective system magnification while maintaining situational awareness. They are often selected when inspectors need to resolve smaller features but still benefit from a wide viewing window for alignment and handling.

When 7.5× Eyepieces Make Sense in Cleanroom Microscopy
Eyepiece magnification as a system decision
Eyepiece selection directly affects effective system magnification, working comfort, and inspection repeatability. Moving from 5× to 7.5× eyepieces increases visual detail without requiring changes to objectives or stands—making it a common optimization step in established inspection stations.
Widefield design and operator efficiency
Super-widefield eyepieces preserve a larger viewing window even at higher magnification. This helps operators maintain orientation, align parts more easily, and reduce repetitive sample repositioning—important factors in both productivity and contamination control.
Balancing detail and ergonomics
While higher magnification eyepieces can reveal smaller defects, they also demand more precise focus control and stable handling. Seven-and-a-half-power eyepieces are often considered a practical upper limit for routine cleanroom inspection before fine-focus mechanisms and tighter SOP controls become critical.
Cleanroom reality check
Increased magnification amplifies everything—including vibration, contamination, and poor technique. Eyepiece upgrades should be paired with disciplined handling and cleaning practices.
Cleaning and maintenance considerations
- Clean eye lenses regularly to prevent haze and contrast loss.
- Use optical-grade swabs and controlled solvent application.
- Include eyepiece barrels in routine microscope wipe-down SOPs.
- Re-verify diopter settings after cleaning or eyepiece changes.
SOSCleanroom technical perspective
Eyepieces are a high-impact, low-disruption upgrade. SOSCleanroom supports Meiji optical systems with compatible eyepieces, Texwipe optical cleaning products, and cleanroom PPE to help customers improve inspection capability while maintaining compliance.
