Planglas, 30 x 15 mm – Flatness reference glass 0.1 µm (Metav IndustryLine)

The Planglas, 30 x 15 mm is a compact flatness reference glass designed for precise surface inspection and checking of small parts in quality-control and calibration workflows

• Flatness accuracy 0.1 µm
• Compact 30 × 15 mm footprint
• Low weight 0.1 kg for easy handling

Consistent measurement quality for surface inspection

The glass reference delivers a clearly defined reference plane with a flatness of 0.1 µm, enabling repeatable comparisons against component faces and small workpieces. Such a tolerance places it in the category of high-precision inspection aids suitable for fine mechanical checks and optical alignment tasks. By using a stable, machined glass surface as the reference, systematic measurement deviations caused by uneven supporting surfaces are minimised, which supports reliable pass/fail assessments in production and incoming inspection.

Space-saving format that fits tight inspection stations

Measuring 30 x 15 mm with a nominal thickness of 12 mm, the reference is sized for compact vice jaws, microscope stages and small bench fixtures where larger plates would be impractical. The small footprint combined with a weight of 0.1 kg makes it simple to position and manoeuvre without auxiliary handling tools, while retaining sufficient cross-section to avoid easy warping. This format is particularly useful where quick visual or tactile verification is required without dedicating large bench space to reference artefacts.

Integrates readily into workshop routines and calibration chains

As a purpose-made parallel pad for flatness checks, the unit is well suited to everyday control tasks such as verifying datum faces, setting up measuring microscopes, or checking planarity before assembly. The specimen offers a clear, stable reference plane for short-range comparisons and is particularly valuable when high-resolution flatness verification is needed on small parts. Its traceable specification and compact design support efficient workflows in tool rooms, small-batch production and laboratory test benches.
