Laser DMC Marking for High-Precision Optical & Microfabricated Components

In regulated, high-value production environments, part traceability is non-negotiable. Laser DMC (Data Matrix Code) marking delivers permanent, machine-readable identification directly on your components—without labels, inks, or secondary processes that can fail under stress.
At Graticules Optics, we apply laser-based 2D Data Matrix Codes compliant with ISO 16022, the industrial benchmark for optoelectronic DMC symbology since the late 1980s. The result: indelible, high-contrast codes that withstand cleaning cycles, vacuum environments, sterilisation, and extreme temperature exposure.

Why Laser DMC Marking?

For senior optical design and production engineers, the value is straightforward:

• Permanent, Direct Part Marking (DPM) – No consumables. No delamination. No adhesive failure.
• Microscale precision – Suitable for fine-feature components including TEM support grids and lift-out grids.
• Material versatility – Metals, ceramics, coated substrates, and specialised optical materials.
• High readability & data density – Robust decoding even at reduced symbol size.
• UDI-ready – Ideal for Unique Device Identification and regulated medical workflows.
• Process-integrated traceability – Seamless integration into MES and quality systems.

Laser marking replaces less reliable serialization methods with durable codes engineered for lifecycle integrity.

Applied Example: TEM & Micro-Sample Traceability

We currently utilise our laser marking process line to uniquely code individual TEM support grids and lift-out grids with microscale Data Matrix identifiers. This enables:

• End-to-end workflow identification for biological and semiconductor wafer samples
• Traceability from collection and preparation through imaging, analysis, and reporting
• Positive identification of individual grids within multi-stage, multi-operator environments
• Reduced risk of sample misidentification or data misattribution

For high-consequence analytical environments, this level of control is essential—not optional.

Designed for Regulated & High-Reliability Sectors

Laser DMC marking is widely deployed in:

• Medical device manufacturing (UDI compliance)
• Automotive safety-critical components
• Aerospace and defence systems
• Semiconductor and advanced materials research
• Precision optics and microfabrication

The marking process is controlled, repeatable, and engineered to preserve component integrity—critical for optical surfaces and precision microstructures.

Technical Confidence. Production Scalability.

Our laser systems are configured for:

• Controlled marking depth and thermal input
• Minimal surface disturbance
• Repeatable contrast optimisation
• Inline or batch production workflows

Whether you require prototype-scale traceability or scalable production marking, the process is engineered around dimensional tolerance, surface finish, and downstream functional requirements.
