This document outlines the technical constraints for the MgF2 crystal substrate, including surface finish and optical performance requirements. Users must confirm coating and tolerance specifications prior to use to avoid compromising optical properties.
- Surface Quality Constraint: The substrate surface roughness must remain below 15 Å to maintain specified transmission performance.
- Polishing Configuration: Single-side or double-side polishing must be selected based on the intended optical application.
- Optical Performance: Transmission must exceed 93% at 5 μm and 85% at 0.2 μm, requiring careful handling to avoid contamination.
- Coating and Tolerance Validation: Coating and tolerance requirements must be confirmed with the supplier before use to ensure compatibility with the intended optical system.
What is the transmission performance of the MgF2 crystal substrate across its specified wavelength range?
The MgF2 substrate transmits from 110 nm to 7500 nm, with >93% transmission at 5 μm in the infrared and >85% at 0.2 μm in the deep ultraviolet. This broad range makes it suitable for combined UV-IR optical components.
What polishing options are available for this MgF2 substrate and how do they affect surface quality?
The substrate is available in single-side or double-side polished configurations, both achieving a surface roughness of less than 15 Å. The choice depends on whether the application requires one or both optical surfaces to be polished.
Is the MgF2 crystal substrate birefringent and what are its refractive indices?
Yes, due to its tetragonal crystal structure, MgF2 is birefringent with ordinary refractive index no = 1.3836 and extraordinary refractive index ne = 1.3957. This anisotropy must be considered in polarization-sensitive optical designs.
The Atomfair MgF2 crystal substrate (10×10×0.5 mm, 10-pack) offers broad transmission from 110 to 7500 nm with high transmission at key wavelengths, low surface roughness, and a choice of single or double-side polishing, making it suitable for UV and IR optical components. However, its Mohs hardness 6 and thin geometry require careful handling during processing and assembly.
Positive
- Broad UV-to-IR transmission range: Transmission wavelength from 110 to 7500 nm covers deep UV through mid-IR, enabling versatile optical component design for spectroscopy and imaging.
- High transmission with low surface roughness: Transmission >93% at 5 μm and >85% at 0.2 μm, combined with surface roughness <15 Å, reduces scatter and insertion loss in precision optical systems.
Trade-offs
- Moderate scratch resistance: Mohs hardness 6 indicates the substrate is susceptible to scratching during handling, cleaning, or mounting, requiring careful surface protection.
- Thin substrate fragility: 0.5 mm thickness increases risk of fracture under mechanical stress or thermal shock, necessitating careful handling in polishing and assembly workflows.
