What is the transmission performance of the MgF2 crystal substrate at key UV and IR wavelengths?
The MgF2 substrate achieves >93% transmission at 5 μm in the IR and >85% at 0.2 μm in the deep UV, with a full transmission range of 110–7500 nm. These values are specified for the standard 5 × 5 × 0.5 mm polished substrate.
What polishing options are available for the MgF2 substrate and how do they affect surface quality?
The substrate is available in single-side polished or double-side polished configurations, both achieving a surface roughness of <15 Å. This low roughness is critical for minimizing scatter in UV and IR optical applications.
What are the key material properties of the MgF2 crystal substrate for optical applications?
The MgF2 crystal has a tetragonal structure with lattice constants a = 4.62 Å and c = 3.04 Å, density 3.18 g/cm³, melting point 1255 °C, Mohs hardness 6, and refractive indices no = 1.3836 and ne = 1.3957. These properties support its use in UV and IR optics.
The Magnesium Fluoride (MgF2) crystal substrate (Atomfair Model AF-MGF2-5) provides a broad transmission range from 110 to 7500 nm with high transmission (>93% at 5 μm, >85% at 0.2 μm) and low surface roughness (<15 A), making it suitable for UV and IR optical components. However, the substrate is supplied uncoated, requiring additional coating and tolerance specification before deployment, as noted in the quotation confirmation.
Positive
- Broad UV to IR transmission range: The MgF2 substrate transmits from 110 to 7500 nm with >93% at 5 μm and >85% at 0.2 μm, and surface roughness <15 A, suitable for high-performance UV and IR optics.
Trade-offs
- Uncoated substrate requires additional processing: The product is supplied as an uncoated substrate; coating and tolerance requirements must be specified before quotation, adding steps before deployment.
