LiF optical window
- High Transmission from 150nm – 6μm
- Excellent Vacuum UV (VUV) Transmission
- Low Index of Refraction
Lithium Fluoride (LiF) optical windows offer excellent UV, visible, and infrared transmission from 120nm to 6µm. They have high damage thresholds, making them ideal for excimer laser applications. LiF windows are widely used in spectroscopy, vacuum UV applications, and thermal imaging systems. With low refractive index and minimal birefringence, they provide superior optical clarity. Custom sizes and coatings are available to meet specific requirements.
