Glass ruler M910.521 — precision reference scale for microscope verification, 0–100 mm range, 0.5 mm graduation

A Glass ruler designed as a compact reference scale for the verification and alignment of microscopes and other optical instruments, offering a clear 0.5 mm graduation and a measurement range up to 100 mm.

• Precision graduation 0.5 mm scale
• Compact 130 mm overall length
• Soda‑lime glass construction for stability
• Lightweight 50 g for portable inspection

Accurate reference for optical alignment

A compact reference scale provides a straightforward baseline for optical checks and calibration workflows. The engraved 0.5 mm graduation and stated accuracy of (1.5 + 2L/1000) µm allow technicians to verify scale consistency and linearity on digital and analogue imaging systems. By offering measurable tolerance data, the instrument supports reproducible alignments and reduces guesswork when comparing imaging magnifications or stage travel. This rational design speeds up routine verification and helps maintain traceable measurement practice in labs and production areas.

Stable glass construction for repeatable results

Manufactured from soda‑lime glass, the scale combines dimensional stability with a flat, scratch‑resistant surface that aids optical contrast under transmitted or reflected illumination. A 5 mm thickness and 30 mm width yield a rigid profile across the full 130 mm length, limiting flex and ensuring consistent contact when placed against stages or reference surfaces. The low mass (approx. 0.05 kg) supports handheld inspections as well as mounted comparisons, while the clear, non‑reflective finish helps with accurate imaging and parallax‑free observation.

Built for workshop and laboratory workflows

Classified for the micro measurement category (measurement range up to 100 mm), this reference scale is particularly suitable for precision optics workshops, educational laboratories and quality control benches where microscope checks are frequent. The compact format fits inspection trays and instrument drawers, enabling quick daily checks without complex setup. For specialised applications or integration into existing routines, Metav Werkzeuge provides application advice and technical documentation to ensure correct use and consistent results.

FAQ

How can this glass ruler be used with microscopes?
The glass ruler M910.521 serves as a visual scale placed on a stage or imaging plane to verify magnification and linearity; its 0.5 mm graduation aids calibration and image measurement checks.

Is the material suitable for routine laboratory use?
Yes, the soda‑lime glass body is dimensionally stable and offers a flat surface that is compatible with common laboratory handling and optical inspection tasks.

What measurement range and resolution does the scale cover?
The instrument covers a measurement range of 0–100 mm with a visible graduation of 0.5 mm, intended for precise reference checks rather than sub‑micron measurement.

Can the ruler be used for both transmitted and reflected illumination checks?
Yes, the engraved scale provides sufficient contrast for both transmitted light and reflected light setups typically used in microscope alignment and verification.

Which applications are typical for this reference scale?
Typical uses include microscope verification, routine optical checks in workshops, educational demonstrations and quality control of imaging systems.
