CaF2 crystal

We supply high-quality Calcium Fluoride (CaF₂) crystals, widely used in optics, spectroscopy, and laser research due to their excellent transmission properties from deep UV to infrared. With low refractive index, minimal birefringence, and high resistance to damage, CaF₂ is a preferred material for demanding optical applications.

Key Features:

• Optical Transmission: 150 nm – 8 µm (UV to IR)
• Low Refractive Index: ~1.43 (no need for anti-reflective coatings in many cases)
• High Laser Damage Threshold: Suitable for high-power laser systems
• Durability: Resistant to moisture, thermal shock, and radiation damage
• Available Forms: Windows, prisms, lenses, substrates, and custom shapes

Applications:

• UV, visible, and IR spectroscopy
• Excimer and CO₂ laser optics
• High-power optical windows and lenses
• Space and aerospace optics
• Semiconductor lithography systems

Ordering Information:

• MOQ: 10 pieces minimum per order
