EWF 10x/20 mm Eyepiece (30 mm Barrel) by Euromex

EWF 10x/20 mm eyepiece for microscope observation and basic measurement tasks, offering a wide apparent field and an integrated micrometre scale with crosshairs for alignment and repeatable inspection

• EWF wide-field design for expanded view
• 10× magnification for routine inspection
• Integrated 10/100 micrometre scale and crosshairs
• 30 mm barrel for standard eyepiece tubes

Precise measurement without complex calibration

The wide-field ocular provides a clear measurement aid through its integrated micrometre scale and fixed crosshairs, enabling straightforward linear comparison and alignment tasks in routine inspection workflows. The combination of 10× magnification and a 20 mm field number increases usable field area, which reduces repositioning and saves cycle time during repetitive checks. As a simple mechanical scale, the micrometre facilitates quick visual readings; for traceable metrology, it serves as a practical reference when paired with calibrated stage scales or digital imaging systems.

Comfortable wide-field viewing for extended use

A larger apparent field supports longer observation sessions with reduced fatigue, making the eyepiece well suited to inspection benches and teaching environments where frequent focus changes occur. The wide-field design increases situational awareness under the microscope and helps operators maintain orientation across the specimen without repeated optical adjustments. The optical layout prioritises a balance of sharpness across the field and comfortable eye relief, which benefits hours-long tasks that demand steady attention rather than extreme magnification.

Seamless integration with existing microscope setups

The eyepiece’s 30 mm barrel diameter conforms to a common standard for many stereo and teaching microscopes, allowing quick exchange with existing oculars and minimal downtime. The mechanical reticle and scale are incorporated directly into the ocular assembly, so the element is ready to use without additional adapters or modifications. This compatibility supports lean equipment strategies: one eyepiece upgrade can extend the measurement capability of several microscopes across a workshop or classroom.

Built for reliable routine inspection and alignment

Designed for daily use in inspection and alignment roles, the eyepiece offers a pragmatic combination of optical performance and mechanical simplicity. The presence of crosshairs allows exact centring for alignment procedures, while the 10/100 micrometre marking assists in coarse sizing and repeat checks. For shops and facilities seeking an economical way to add basic measurement functionality to optical systems, this ocular provides a durable, no-fuss solution that complements calibrated instruments and digital capture workflows.

FAQ

How does the micrometre scale on this eyepiece work? The micrometre scale is an engraved visual scale within the eyepiece; the EWF 10x/20 mm eyepiece by Euromex provides a 10/100 micrometre marking for quick comparative measurements and alignment under magnification

Can this eyepiece be used in stereo microscopes with a 30 mm tube? Yes, the eyepiece is designed with a 30 mm barrel and fits standard 30 mm eyepiece tubes commonly found on stereo and teaching microscopes

Is the eyepiece suitable for long inspection sessions? The wide apparent field and comfortable optical layout of the Euromex eyepiece reduce eye strain and support longer observation periods for routine inspection tasks

Will the crosshairs affect image quality for observation? The integrated crosshairs are designed for alignment and centring and have minimal impact on overall image quality when using the EWF 10x/20 mm eyepiece

Is the micrometre sufficient for precision metrology? The micrometre scale in this ocular offers practical, repeatable reference readings; for traceable precision metrology, combine the eyepiece with calibrated stage scales or digital measurement systems
