What is the expected transmission of the 0.5 mm thick CaF2 substrate across its specified wavelength range?

The CaF2 substrate has a transmission range of 0.11 to 12.00 μm. Transmission values are specified as >94% at 5 mm thickness and >85% at 0.2 mm thickness. For the 0.5 mm substrate, transmission will fall between these values, providing high throughput in the infrared region.

What are the primary applications of this (111)-oriented, single-side polished CaF2 substrate?

This substrate is designed for infrared optical components including windows, prisms, and lenses. Its wide transmission range (0.11–12.00 μm) and polished surface make it suitable for IR spectroscopy, thermal imaging, and laser optics.

What surface roughness specification does this CaF2 substrate meet?

The substrate has a surface roughness of Ra < 5 Å for routine processing, ensuring low scatter and high optical quality for demanding infrared applications.

Calcium fluoride (CaF2) crystal substrate (5×5×0.5 mm, (111) orientation, single-side polished) offers transmission from 0.11 to 12.00 μm with >94% at 5 mm thickness, making it suitable for broadband IR optics, but its low hardness (4) and high thermal expansion coefficient (18.85×10^-6/°C) require careful handling and thermal management.

Positive

  • Broad UV-to-IR transmission range: Covers 0.11–12.00 μm, enabling deep UV to far IR applications in spectroscopy and optical windows without absorption gaps.
  • High transmission at useful thicknesses: >94% transmission at 5 mm and >85% at 0.2 mm indicate low absorption and suitability for bulk and thin-film optical components.

Trade-offs

  • Low hardness requires careful handling: Mohs hardness of 4 makes the material prone to scratching and surface damage during polishing, cleaning, or mounting.
  • High thermal expansion coefficient: 18.85×10^-6/°C expansion rate may cause thermal stress or misalignment in assemblies with dissimilar materials under temperature cycling.
