Edmund Optics® (EO), a renowned provider of optical components, continuously expands its product offering to reflect market developments and customer needs. New products are added each month to better serve the industry. Edmund Optics has released new windows in a wide variety of infrared (IR) materials including Gallium Arsenide (GaAs), Barium Fluoride (BaF2), Cadmium Telluride (CdTe), Thallium Bromoiodide (KRS-5), Lithium Fluroide (LiF), and a chalcogenide material called AMTIR-1, resulting in a one-stop shop for IR windows.
Each substrate material has some numerous advantages and disadvantages compared to the others. GaAs is a very tough and durable material which is useful as a protective window in laser material processing where abrasive debris particles are expected. BaF2 has a wide transmission that extends from IR, through the visible spectrum, into deep ultraviolet (UV) without the need for an anti-reflection (AR) coating. BaF2 can also be used in environments with temperatures up to 800°C. CdTe features a broad, flat transmission spectrum from IR to longwave IR (LWIR) and are useful with low power CO2 laser systems or for spectroscopy applications.
KRS-5 windows feature flat transmission from IR to far IR and with resistance to chemicals (except strong acids) making them useful as protective windows for acid-sensitive applications and Fourier transform infrared spectroscopy (FTIR) spectroscopy. With a wavelength range from deep UV to medium wave IR (MWIR), LiF windows are excellent for use in thermal imaging applications or in X-ray spectrometry. AMTIR-1 features excellent resistance to acids, do not experience thermal runaway, and can be used in temperatures up to 300°C, making them ideal for use as protective windows for IR and forward-looking infrared (FLIR) imaging systems or IR laser systems.
