Barium Fluoride (BaF₂) Plano-Convex (PCX) lenses are high-performance optical lens widely used in ultraviolet (UV), visible, and infrared (IR) applications.
With an exceptionally wide transmission range from 150 nm to 12 µm, BaF₂ lenses are highly valued in spectroscopy, laser optics, and infrared imaging systems.
Also, their low refractive index and good radiation resistance make them a reliable choice for demanding optical designs.
Key Features of BaF₂ PCX Lenses
- Broad Spectral Transmission:
From deep UV (150 nm) to long-wave IR (12 µm).
- Low Refractive Index (~1.46):
The lenses minimize surface reflections and simplifies system design.
- High Damage Threshold:
Well-suited for high-power laser and UV applications.
- Excellent Radiation Resistance:
Stable under high-energy radiation, ideal for aerospace and defense.
- Good Thermal Stability:
BaF₂ PCX Lenses can operate effectively across a wide temperature range compared with common lenses.
What are Barium Fluoride Plano-Convex (PCX) Lenses used to?
- Perfect for UV, mid-IR, and thermal IR spectroscopic instruments.
- Thermal cameras and IR detectors.
- Effective in both UV and IR laser optics.
- Radiation-hard properties suit space-based optical systems.
- Imaging, lithography, and diagnostic equipment.
When using barium fluoride, be aware that it is a hazardous material.
For your safety, please wear gloves when handling these lenses and wash your hands thoroughly after the handling.
