Glass ruler M910.522 — soda‑lime glass, 0.5 mm scale (Metav IndustryLine)

The Glass ruler M910.522 is a compact inspection ruler designed for precise verification of microscopes and small optical assemblies, offering a clear scale and stable dimensions for routine quality checks.

• Soda‑lime glass body for dimensional stability
• 0.5 mm graduation for clear readings
• 230 mm overall length for workshop use
• High accuracy: (1.5+2L/1000) µm specification

Reliable accuracy for routine microscope checks

The ruler’s metrological specification, quoted as (1.5 + 2L/1000) µm, indicates a length‑dependent tolerance that remains exceptionally small across usual inspection distances; this ensures repeatable results when assessing optical stages or scale calibration. In practice, the fine 0.5 mm graduation combined with the stated tolerance supports consistent visual comparison and routine verification tasks in laboratories and teaching environments, reducing ambiguity in read‑outs and speeding up inspection cycles.

Stable construction that aids handling and readability

Manufactured from soda‑lime glass, the instrument provides a smooth, non‑reflective surface that keeps the engraved scale legible under typical workshop lighting. The profile, with a 30 mm width and 5 mm thickness, balances stiffness and manoeuvrability: it resists minor bending during handling while remaining light at 0.08 kg, so technicians can position it quickly on stages or specimens. The design minimises flex and helps maintain parallelism during placement, which contributes directly to measurement reliability.

Practical integration into quality workflows

As a compact, workshop‑oriented tool, the ruler fits standard inspection kits and serves as a fast-reference standard for incoming inspection, educational labs and routine maintenance of optical equipment. Its 230 mm overall length covers most common sample sizes for microscope verification without excess bulk, supporting efficient comparison tasks and repeatable set‑ups. The clear scale and robust form factor make it a dependable companion for production lines and bench tests where straightforward, reproducible checks are required.

FAQ

What does the accuracy formula (1.5 + 2L/1000) µm mean in practice?
The specification denotes a permissible deviation that increases slightly with the measured length L, so short inspection distances yield the tightest tolerances; the Glass ruler M910.522 therefore provides the most precise comparative readings over typical microscope stage spans.

Is this ruler suitable for routine quality control in workshops?
Yes, the compact 230 mm format and clear 0.5 mm graduation make it suitable for routine checks and quick verifications in workshop and laboratory environments.

Which materials and applications is the ruler intended for?
The instrument is made from soda‑lime glass and is intended primarily for optical verification tasks such as scale checks and alignment of microscopes and small optical assemblies.

How should the ruler be handled and stored to preserve accuracy?
Handle the ruler with care to avoid edge chipping; store it flat or in a protective tray to prevent bending and keep the engraved scale clean for consistent readings.
