These calibration patterns are made from high-quality soda-lime glass, offering excellent stability and durability for daily use in machine vision and precision measurement environments. They are widely used for calibrating optical systems, XY stages, and various 2D measurement setups.
With a feature-to-feature accuracy of up to 1 micron, the targets provide the precision required for system testing, alignment, and performance verification. You can select different dot sizes and spacing options depending on your specific calibration needs.
Grid arrays are commonly used to check and correct imaging distortion. In an ideal system, all rows and columns should remain perfectly perpendicular. If the captured image shows bent or curved grids, the distortion pattern can be analyzed and used for system compensation.

We start with high-quality soda-lime glass or ceramic substrates to ensure stability and long-term precision.
The calibration pattern is written onto the coated chrome layer using a high-precision laser system for consistent accuracy.
The exposed areas are developed to reveal the pattern structure.
The chrome layer is etched to form clean, high-contrast features with sharp edges.
Residual photoresist and impurities are removed to achieve a smooth, flawless surface.
Each target is carefully inspected. Any defects are corrected to maintain micron-level accuracy.
A protective pellicle film can be added to prevent dust contamination, especially for demanding environments.
Every calibration target undergoes strict quality checks to ensure it meets industrial precision standards before shipment.

One of the advantages of quartz glass is Low Thermal Expansion Rate (CTE): <5.0*107, it delivers superior thermal stability (0.55um/°C vs 8.5um/°C). Essential for precision measurements, optional for general testing applications.
Unless you need exceptional thermal stability, soda lime glass delivers excellent performance at a fraction of the cost of quartz glass.
