Frequently Asked Questions

Q1: How does the dual-side polish affect the substrate’s optical performance?
A1: The dual-side polish minimises surface roughness, reducing light scattering and enhancing transmittance. This is critical in systems where optical clarity and accurate light propagation are essential.

Q2: What storage conditions are recommended for the CaF2 substrate?
A2: The substrate should be stored in a low-humidity, temperature-controlled environment. Cleanroom conditions with minimal particulate exposure are preferred to maintain its surface integrity and optical properties.

Q3: Can the (111) orientation impact the substrate’s performance in optical systems?
A3: Yes, the (111) crystallographic orientation offers a uniform surface structure that aids in achieving consistent light transmission and reduces internal scattering, which is beneficial for high-precision optical measurements.

Additional Information

Calcium Fluoride (CaF2) substrates are widely used in optical systems due to their excellent transmission properties in the ultraviolet to infrared range. The inherent characteristics of CaF2, such as low refractive index variation and minimal birefringence, make it a suitable material for high-resolution optical devices. Additionally, the crystallographic orientation plays a crucial role in achieving uniform surface properties, which is essential in precision optical measurements.

In research and industrial settings, the detailed control of substrate surface quality is paramount. Techniques such as interferometric surface analysis and advanced polishing processes help achieve the stringent tolerances required for modern optical components. This level of control supports the development of systems that demand consistent optical performance under varying operational conditions.
