- High-Energy Radiation Resistant
- Transmission is excellent between 200nm - 12μm.
- Provide high transmission without the use of AR coatings.

Barium Fluoride (BaF2) is the fastest known scintillator material; it has characteristics comparable to calcium fluoride but is more resistant to high-energy radiation. It is, however, more susceptible to water damage. Features
-
Brewster Windows are windows that are meant to be used at Brewster's angle (usually uncoated). This is the angle at which only incident p-polarized light has 0% transmission loss. Instead of exterior mirrors, a Brewster window is an uncoated substrate positioned at Brewster's angle within a laser. This substrate works as a polarizer, allowing p-polarized light to enter and exit the window without reflection losses while reflecting s-polarized light. Features
- Perfect for Laser Cavities.
- A substrate with UV Fused Silica.
- Without Reflection Losses, P-Polarized Light is Transmitted.

Calcium Fluoride (CaF2) Windows have a high damage threshold and low absorption and are transparent from 180 nm to 8µm. It is a great choice for FTIR analysis, excimer laser systems, spectroscopic windows, and thermal imaging systems. Features:
- <1 arc-minute parallelism
- Ideally suited for excimer laser applications.
- Transparent in UV, visible, and infrared light.
- A low absorption rate and a high damage threshold
- In comparison to other IR materials, it has a low chromatic aberration.
-
The mechanical properties of Sapphire include its great strength, thermal stability, wear resistance, and chemical inertness. As a result, a Sapphire Window outperforms other optical materials in severe conditions, acting as a shield between the elements. In optical and mechanical applications, sapphire windows are often used. Features
- Chemical resistance due to its high surface hardness.
- Transmits light at wavelengths ranging from ultraviolet to near-infrared.
- Thinner and stronger than standard glass windows.
- Available with anti-reflection coatings ranging from 400 to 5000nm
