The Optical Composite Image Level is a high-precision industrial instrument engineered for the rigorous demands of modern manufacturing and quality control. Specialized for measuring gradients on both flat and cylindrical surfaces, this tool is indispensable for verifying the planeness and straightness of machine tool slideways, optical mechanical instrument bases, and the precise installation alignment of heavy industrial equipment.
By leveraging an advanced optical prism system combined with a magnifying lens, the instrument transforms subtle air bubble movements into clear, readable images, significantly enhancing measurement sensitivity. With a graduation value of 0.01mm/m and a professional V-groove working surface, it provides the stability and accuracy required for CNC machine alignment, aerospace component inspection, and high-end metal fabrication processes.

The composite image system utilizes prisms and magnifying glasses to make bubble alignment visually intuitive and precise.
Dual-surface base (Plain and V-groove) allows seamless switching between flat surfaces and cylindrical workpiece measurements.
Integrated lever and micro-adjusting screw system significantly amplify reading sensitivity for minute gradient changes.
Supports the professional 180° rotation method to eliminate zero-position drift and ensure repeatable industrial results.
Engineered with high-grade materials and a precision-ground base (Ra ≤ 0.1μm) for long-term dimensional stability.
Systematic cleaning with isopropyl alcohol and lint-free cloths to protect the Ra ≤ 0.1μm precision surfaces.
Application of non-acidic, anhydrous anti-rust oil to protect critical levers and micro-screws from oxidation.
Storage in temperature-stabilized environments (10°C–30°C) to prevent optical distortion and condensation.
Routine 180° rotation calibration to ensure the instrument remains at the center of its 0.01mm/m precision.
Monthly inspections of bubble clarity and lever movement to ensure backlash-free operational smoothness.
ISO-certified factory recalibration using laser interferometers to restore original NIST-traceable accuracy.

| Long-term Drift | Higher susceptibility | Low (Stabilized Prism System) |
Unlike standard levels, it uses a 45° prism and magnifying system to create a composite image of the bubble, allowing for a much finer graduation of 0.01mm/m compared to the usual 0.1mm/m.
The V-groove allows the instrument to be placed securely on cylindrical surfaces (such as shafts or rollers) to measure their gradient relative to the horizontal direction with high stability.
We recommend performing calibration before critical measurements, after transporting the tool, or quarterly for heavy industrial use to eliminate any zero-position drift caused by vibration.
Temperature changes can influence measurement accuracy. It should be kept away from direct heat sources and ideally used in stabilized environments between 18°C and 22°C for peak precision.
Only use non-acidic, anhydrous anti-rust oil. This prevents chemical reactions with the metal components and ensures the micro-adjusting screws remain smooth and backlash-free.
Yes, every Storaen optical composite image level comes with a NIST-traceable calibration certificate to ensure it meets international standards for precision metrology.
