Frequently Asked Questions

Q1: What is the significance of the (111) orientation in this CaF2 substrate?
A1: The (111) orientation ensures a uniform crystal structure that reduces internal scattering. This is critical in optical applications where consistent propagation of light is required and defects must be minimised.

Q2: How does the one side polished surface benefit optical applications?
A2: The one side polished surface provides an optically smooth finish, minimising light scatter and enhancing transmission efficiency. This surface quality is essential for precision optical measurements and component integration.

Q3: What storage conditions are recommended for this substrate?
A3: The substrate should be stored in a clean, low-humidity environment at a controlled room temperature. Using moisture barrier packaging and static-dissipative materials helps maintain its surface integrity and optical properties over time.
