• Excellent Transmission from 200 nm - 12 μm
• Resistant to High-Energy Radiation
• Provide High Transmission without AR Coatings
TECHSPEC® Barium Fluoride (BaF2) Windows can be used in a
variety of applications, such as infrared spectroscopy, due to their
wide broadband transmission that extends from the deep ultraviolet
to the long-wave infrared. Barium fluoride windows can be
used up to 800°C in a dry environment, but prolonged exposure
to moisture can degrade transmission in the vacuum ultraviolet
range. While barium fluoride windows are less resistant to water
than calcium fluoride, BaF2 windows are the most resistant optical
fluoride to high-energy radiation, but feature lower UV transmittance.
BaF2 has a Knoop hardness of 82. Note: These optical windows
are very sensitive to thermal shock.

• Low Absorption, High Transmission UV Grade
Calcium Fluoride
• Ideal for Applications Ranging from 250 nm - 7 μm
• Low Index of Refraction
Calcium fluoride is often used in spectroscopic windows and lenses
due to its high transmission from 250 nm to 7 μm. Its low absorption
and high damage threshold makes it a popular choice for excimer
laser optics. Calcium fluoride’s low index or refraction allows it to be
used without an anti-reflective coating. The Knoop hardness of calcium
fluoride is 158,3. TECHSPEC® Calcium Fluoride (CaF2) Windows
manufactured from vacuum UV grade calcium fluoride are
commonly found in cryogenically cooled thermal imaging systems.

• Excellent Transmission from 120 nm - 7 μm
• Rugged and Durable
• Resistant to Chemical Etching
TECHSPEC® Magnesium Fluoride (MgF2) Windows offer excellent
broadband transmission from the deep-UV to the mid-infrared.
DUV transmission makes them ideal for use at the Hydrogen Lyman
alpha line and for UV radiation sources and receivers, as well
as excimer laser applications. MgF2 is a rugged material resistant to
chemical etching, laser damage, and mechanical and thermal shock.
It has a Knoop Hardness of 415 and index of refraction of 1,38.
