TECHSPEC® Barium Fluoride (BaF₂) Windows Provide High Transmission without AR Coatings

Edmund Optics® (EO), the premier provider of optical components, introduces its new TECHSPEC® Barium Fluoride (BaF₂) Windows. These windows are ideal for use in a wide variety of applications, including infrared (IR) spectroscopy, as they offer wide broadband transmission extending from the deep ultraviolet (UV) to the long-wave IR.

Resistant to High-Energy Radiation

With excellent transmission from 200nm to 14μm, TECHSPEC Barium Fluoride (BaF₂) Windows take advantage of Barium Fluoride’s low index of refraction (1.48), which provides high transmission without the need for anti-reflection (AR) coatings. The windows can be used at temperatures up to 800°C in a dry environment. TECHSPEC Barium Fluoride (BaF₂) Windows are made from the most resistant optical fluoride to high energy radiation and feature a Knoop hardness of 82.

BaF₂ detects high energy particles

Barium Fluoride is a very fast scintillator for the detection of X-rays, gamma rays, and other high energy particles, such as 511 keV gamma photons in Positron Emission Tomography (PET). It is also used to detect high-energy (10-150 MeV) neutrons and separate them from simultaneously occurring gamma photons using pulse shape discrimination techniques.

Four models available with diameters from 5mm - 50mm

TECHSPEC Barium Fluoride (BaF₂) Windows are available in four models with diameters from 5mm to 50mm. They are in-stock and available for immediate delivery for fast turnaround and excellent value.
