Custom Optical Gratings & Ronchi Rulings

Custom Optical Gratings & Ronchi Rulings

We provide custom optical gratings and Ronchi rulings manufactured according to your required dimensions, line density, substrate material, and optical pattern. Both standard and fully customized designs are available for research, imaging, optical testing, spectroscopy, calibration, and industrial applications.

Customization Options

• Pattern: Ronchi ruling, line grating, slit array, grid, checkerboard, or customer-supplied design
• Line density: Custom lines per inch (LPI) or lines per millimeter
• Duty cycle: Standard 50% or customized line-to-space ratio
• Substrate materials: Borosilicate glass, fused silica, quartz, sapphire, or other optical substrates
• Pattern materials: Chromium, chromium oxide, or other suitable metal coatings
• Dimensions: Small laboratory samples to large-format optical gratings
• Shape: Square, rectangular, circular, or custom geometry
• Clear aperture and border: Customized according to your optical setup

Available Features

• High-contrast opaque and transparent line patterns
• Fine linewidth and accurate line spacing
• Large-format gratings available
• Custom alignment marks, labels, borders, and mounting holes
• Single prototypes and small production quantities
• Design review and final layout confirmation before production

Applications

• Optical system resolution testing
• Camera and imaging-system calibration
• Laser alignment and beam characterization
• Spectroscopy and diffraction experiments
• Moiré pattern and displacement measurements

How to Request a Quote

Please send us your drawing or provide the following information:

1. Overall substrate dimensions and thickness
2. Substrate material
3. Line density, pitch, or linewidth
4. Transparent and opaque line widths
5. Patterned area or clear-aperture size
6. Required quantity
7. Any special requirements for coating, mounting holes, edge finishing, or dimensional tolerance

Design files in PDF, DXF, DWG, GDS, Gerber, or other common formats are accepted. After the order is placed, we will prepare a final layout for your approval before manufacturing.

Typical lead time: 3–6 weeks, depending on the dimensions, pattern resolution, material, and quantity.
