Sharper Slits. Clearer Results

High-precision electroformed metal foil and chrome-on-glass apertures, slits, pinholes, and multi-apertures engineered for demanding optical, scientific, and industrial applications.

Precision Engineered for Superior Optical Performance

When beam quality matters, edge quality matters.

Our electroformed metal foil apertures are manufactured to deliver exceptional edge definition, straightness, and roundness. These critical characteristics minimise light scatter and provide highly accurate beam shaping, resulting in improved measurement accuracy and optical performance.
Whether you require standard products or bespoke solutions, our precision manufacturing ensures reliable, repeatable results every time.

Why Electroforming is Best

At Graticules, we have perfected electroforming processes to create the highest-quality precision apertures available.
Unlike conventional manufacturing methods, electroforming builds metal layer by layer, producing exceptionally smooth and sharply defined aperture edges. This unique process creates superior edge geometry and aperture shape, significantly reducing unwanted light scatter while generating cleaner, better-defined beam profiles.
The result is a precision component that delivers enhanced optical performance where accuracy is critical.

Benefits of Electroforming

• Superior slit edge definition
• Reduced light scatter
• Improved beam quality and shape
• Exceptional straightness and roundness
• High dimensional accuracy
• Consistent and repeatable performance

The microscope images below clearly demonstrate the difference, highlighting why electroforming remains the preferred choice for high-performance optical apertures.

Advanced Chrome-on-Glass Technology

For complex patterns and ultra-fine features, we manufacture chrome-on-glass products using vacuum-deposited chrome and precision photolithographic techniques.
This process enables the creation of intricate micro-patterns with outstanding image definition, dimensional accuracy, and repeatability.
