Frequently Asked Questions

Q1: How does the dual-side polishing enhance the substrate’s performance?
A1: Dual-side polishing reduces surface roughness and minimises scattering losses, which improves the optical clarity and performance in high-resolution systems. This process is critical in applications requiring precise light propagation and minimal surface interference.

Q2: What handling precautions are recommended for these substrates?
A2: These substrates should be handled in a clean environment using lint-free gloves to avoid contamination. They must be stored in temperature and humidity-controlled conditions to maintain the integrity of the polished surfaces and overall dimensional accuracy.

Q3: Can the substrate be customised for specific processing requirements?
A3: Yes, customisation options are available for dimensions, surface finish, and packaging. Adjustments can be made to meet specific requirements, such as tailored thickness or special storage conditions, to suit particular optical or semiconductor process needs.

Additional Information

Calcium Fluoride (CaF2) substrates are widely utilised in optical applications due to their low refractive index and minimal optical absorption in the ultraviolet and infrared spectra. The material’s inherent chemical inertness and thermal stability make it a viable option for high-precision optical components and integrated circuit fabrication.

Advancements in materials processing have enabled the production of CaF2 substrates with controlled crystallographic orientations and improved surface finishes. Such enhancements support their application in sophisticated imaging systems and semiconductor processes, where precise dimensional control and low-defect densities are paramount.
