Glass ruler M910.257 — glass rule for microscope verification, 0–300 mm range, 0.1 mm graduations (Metav IndustryLine)

The Glass ruler M910.257 is a precision glass rule designed for verification and calibration of optical instruments and fine measurement tasks over a 0–300 mm span.

• 0–300 mm measurement range
• 0.1 mm fine graduation
• Soda‑lime glass construction
• Delivered in protective case

Accurate optical reference that simplifies microscope checks

The instrument serves as a stable optical reference: the (1.5 + 2L/1000) µm formula defines the metrological tolerance across the measuring length and allows users to estimate expected deviation at any point along the scale. With a 0–300 mm measuring span and 0.1 mm divisions, the rule provides a readable, application‑oriented resolution for routine checks and comparative measurements. This clarity in specification reduces ambiguity in inspection protocols and supports efficient decision‑making in the quality workflow.

Robust material and compact form for consistent handling

Made from soda‑lime glass, the rule balances rigidity and fine edge definition to keep graduations sharp and reproducible. The overall length of 330 mm, combined with a width of 30 mm and a thickness of 5 mm, yields a low‑mass reference (approx. 0.12 kg) that is easy to manoeuvre yet stable against minor flexing. Delivery in a protective case ensures safe transport and preserves the scale during storage, which is particularly valuable when the rule is used intermittently across labs or production cells.

Integrates with optical inspection routines and workshop processes

As an instrument intended for microscope verification and optical comparisons, the rule is straightforward to incorporate into established procedures: lay the rule on the specimen stage or reference plane, align the microscope field and document deviations against the printed scale. The clear 0.1 mm graduations aid visual alignment and quick documentation, supporting traceable inspection records. For facilities seeking a reliable visual standard without complex electronics, this glass rule provides a practical, low‑maintenance option that complements digital and analogue measurement systems.

FAQ

How precise is the glass ruler for microscope verification?
The stated tolerance is given by the formula (1.5 + 2L/1000) µm; this defines the expected deviation across the length of the Glass ruler M910.257 and enables reliable comparative verification of optical instruments.

Can the rule be used directly on a microscope stage?
Yes, the design and dimensions of the Glass ruler M910.257 allow direct placement on many microscope stages for visual alignment and quick scale checks.

What protection is provided during transport?
The rule is supplied in a protective case suitable for transport, which reduces the risk of damage to the graduations and helps preserve the optical reference surface.

Is the material suitable for workshop use and repeated handling?
The soda‑lime glass construction combines sharp graduation definition with sufficient mechanical stability for routine handling; the low mass (approx. 0.12 kg) and compact form factor aid practical use in inspection environments.

Which category does this instrument belong to and what is it best used for?
Listed among rulers/lineals, the Glass ruler M910.257 is best suited as an optical reference for microscope verification, scale checks and other fine visual inspection tasks.
