🔬 Infrared (IR) Optics

• IR Windows & Lenses
  Excellent transmission in the 0.15–12.5 µm range makes BaF₂ ideal for windows and lenses used in infrared spectroscopy, thermal imaging, and gas analysis systems.

• High-Performance FTIR Systems
  Used as beam splitters and sample windows in Fourier-transform IR (FTIR) spectrometers due to its wide transmission range and low absorption.

🔭 UV and Laser Applications

• Excimer Laser Windows
  UV-grade BaF₂ is suitable for 193 nm excimer lasers due to high UV transmittance and resistance to radiation damage.

• UV Beam Delivery
  Efficient for delivering UV radiation in photolithography, medical UV treatment, and scientific light sources.

⚛ Scintillation Detectors

• Gamma-Ray & X-Ray Detection
  BaF₂ scintillators are used in nuclear physics, medical imaging (PET/CT), and homeland security because of:

  • Fast decay time (~0.6 ns component)

  • Moderate light output

  • Radiation hardness

🛰 Aerospace & Defense

• Infrared Targeting Systems
  Used in airborne or spaceborne IR seekers due to wide-range IR transparency and stable optical properties.

• Space Optics
  Low UV degradation makes it suitable for space-based sensors and detectors.
