Glass line scale
A glass substrate with clear graduations provides a length reference for vision measurement, microscope observation, and metrology calibration.
Glass line scales
Custom glass line scales
Glass line scales for profile projectors, microscopes, video measuring machines, and metrology calibration. Range, divisions, graduation layout, outer profile, and accuracy grade are confirmed by the equipment use.
Start from the use case
How should a glass line scale match the equipment?
A glass line scale provides a length, division, and position reference. Range, division value, graduation direction, zero, effective area, and mounting should match the field of view, magnification, and reading method.

Technical confirmation
Glass-scale confirmation path
- 01
Start from range and field of view
Confirm the area visible in one capture, then set the overall range and graduation distribution.
- 02
Fix divisions and reading method
Record the smallest division, unit, zero, and software or visual reading method.
- 03
Confirm glass and profile
Set the glass specification from the mounting space, edge protection, thickness, and surface requirement.
- 04
Lock inspection and packaging
Define graduation inspection, dimensional accuracy, quantity, separators, protection, and delivery.
FAQ
Glass line scale questions
Can a glass line scale calibrate a video measuring machine?
It can provide a length and image-scale reference. Range, divisions, graduation direction, magnification, and reading method must match the machine.
Does a smaller division automatically make measurement more accurate?
No. Division value also has to match lens resolving power, software recognition, glass flatness, and the actual reading method.
Can the glass scale include a special outline or mounting holes?
It can be assessed from drawing. Provide the profile, holes, effective graduation area, mounting constraints, and edge-treatment requirement.
Range, divisions, graduation accuracy, profile, glass specification, and lead time are governed by the technical confirmation sheet.
