EWF 10×/20 mm eyepiece with crosshairs, Ø 30 mm tube — Euromex wide-field inspection eyepiece

The EWF 10×/20 mm eyepiece with crosshairs is a wide-field eyepiece designed for precision alignment and visual inspection on microscopes equipped with a 30 mm eyepiece tube

• Wide-field view, 20 mm field number
• 10× fixed magnification for clear detail
• Integrated crosshairs for alignment tasks
• Fits 30 mm eyepiece tubes

Enhanced visual field for faster inspection and decision-making

The wide-field optical design delivers an enlarged apparent field of view, indicated by the 20 mm field number, which permits more of the specimen to be seen at once. With a 10× magnification, fine details are brought into clear focus while preserving situational overview, reducing the need for frequent stage movement. This combination supports more efficient visual inspection cycles and lowers throughput times in quality-control routines. The optical characteristics are well suited to tasks where rapid identification of features is required rather than high-magnification measurement.

Precise alignment and reference with integrated crosshairs

An integrated crosshair reticle provides a fixed visual reference that simplifies alignment, centring and comparative checks. The reticle enables repeatable positioning during assembly checks or when marking coordinates for documentation. For users requiring documented references, the reticle serves as a stable visual datum that can be combined with calibrated stages or camera systems to transfer positional information. This function supports workflow consistency in inspection and assembly processes, improving traceability without introducing complex calibration steps.

Robust compatibility and workshop-ready design

Engineered as an EWF (extra wide field) eyepiece for microscopes with a 30 mm tube, the optic is a straightforward upgrade for many bench and laboratory systems. The eyepiece’s mechanical dimensions ensure simple interchangeability with standard ocular tubes, while the wide-field optics enhance ergonomic comfort during prolonged examinations. Its straightforward configuration reduces downtime for replacement and keeps instrument maintenance uncomplicated. Suitable for production inspection, laboratory evaluation and general workshop use, the eyepiece combines practical compatibility with optical performance.

FAQ

Which microscopes are compatible with this eyepiece?
The EWF 10×/20 mm eyepiece with crosshairs is designed for microscopes that accept a 30 mm eyepiece tube and follows the EWF wide-field eyepiece format.

Can this eyepiece be used for basic measurement or alignment tasks?
Yes, the built-in crosshair reticle in the EWF 10×/20 mm eyepiece provides a stable reference for alignment and coarse positional checks; for calibrated dimensional measurement, additional stage scales or camera calibration is recommended.

What does the field number (20 mm) mean in practice?
A 20 mm field number denotes the diameter of the visible field at the eyepiece’s image plane; higher field numbers give a larger viewing area, which speeds inspection by showing more of the specimen at once.

Is the magnification adjustable?
The eyepiece provides a fixed 10× magnification; variable magnification requires changing objectives or using a different eyepiece with a different magnification.

What is the SKU for ordering and specification reference?
The product is listed under SKU IS.6310-C and can be referenced when discussing compatibility or placing an order.
