What is the birefringence of the Atomfair MgF2 crystal substrate and why is it important for optical applications?
The MgF2 substrate has ordinary refractive index no=1.3836 and extraordinary ne=1.3957, yielding a birefringence of 0.0121. This uniaxial positive birefringence is critical for designing polarization-sensitive components such as waveplates, polarizers, and beam displacers.
What is the usable transmission range of this MgF2 substrate and what are the guaranteed transmission values?
The transmission wavelength range is 110–7500 nm, covering deep UV to mid-IR. Guaranteed transmission is >93% at 5 μm and >85% at 0.2 μm, making it suitable for UV-grade windows and IR optics.
What polishing options are available for this MgF2 substrate and what surface roughness can be expected?
Both single-side and double-side polishing are available as routine processing options. The surface roughness is specified as <15 Å, ensuring low scatter for precision optical applications.
This MgF2 crystal substrate provides a broad 110-7500 nm transmission range with >93% transmission at 5 μm and >85% at 0.2 μm, combined with a surface roughness below 15 A, making it a suitable candidate for UV and IR optical components. The thin 0.5 mm geometry and requirement to confirm coating and tolerance specifications before quotation are key operational considerations.
Positive
- Broad UV-IR transmission window: The substrate transmits across 110-7500 nm with >93% at 5 μm and >85% at 0.2 μm, covering deep UV to mid-IR applications.
- Precision surface finish: Surface roughness is specified below 15 A with single- or double-side polishing options, minimizing scatter for optical use.
Trade-offs
- Thin substrate fragility: At 0.5 mm thickness, the substrate is mechanically fragile and requires careful handling to avoid breakage during processing or mounting.
- Customization prerequisites: Coating and tolerance requirements must be confirmed before quotation, indicating that the standard product may need additional processing to meet specific application needs.
