Description
Chrome on glass reticles are precision optical components designed for alignment, measurement, calibration, targeting, and image reference applications. Manufactured on optical glass substrates with precision chrome patterns, these reticles provide clear, high-contrast reference markings for optical instruments and imaging systems.
Jiujon Optics manufactures custom chrome on glass reticles according to application-specific requirements, including substrate material, reticle pattern, line width, dimensions, coating characteristics, and clear aperture. The combination of precision glass processing and chrome patterning allows the reticle to be integrated into demanding optical assemblies where dimensional accuracy and pattern consistency are important.

Applications
Chrome on glass reticles are used in a variety of optical and optoelectronic systems where a stable reference pattern is required.
Typical applications include:
- Optical instruments and measurement equipment
- Microscope and imaging system calibration
- Surveying and alignment instruments
- Machine vision and optical inspection systems
- Laser alignment and positioning equipment
- Scientific and analytical instruments
- Targeting and aiming optical systems
- Custom OEM optical assemblies
For measurement and calibration applications, reticles can incorporate scales, crosshair patterns, grids, reference marks, or other customer-defined geometries. Pattern dimensions and positioning can be customized to match the optical design of the instrument.
Precision Reticle Manufacturing
The manufacturing process combines optical glass processing with precision pattern formation. Depending on the application, Jiujon Optics can provide glass cutting, grinding, polishing, cleaning, chrome coating, pattern processing, and optical inspection.
Chrome-coated areas can be designed to provide high optical density, while transparent areas allow light transmission through the required portions of the reticle pattern. This structure enables the reticle to provide a defined visual reference without unnecessarily affecting the optical path.
For OEM projects, customers can provide drawings or technical specifications covering the overall dimensions, substrate, thickness, pattern geometry, line width, tolerance, and optical requirements. Jiujon Optics can then manufacture the reticle according to the specified design.
