Infrared optics with broadband anti-reflective coatings

Edmund Optics (EO) has introduced an expanded offering of off-the-shelf infrared (IR) optics featuring broadband anti-reflective (BBAR) coatings. These include 3-5μm coating options on silicon PCX lenses and silicon windows and 8-12μm coating options on germanium PCX lenses and germanium windows.  

TechSpec silicon windows and PCX lenses are manufactured from optical grade silicon, which has a low density of 2.329 g/cm3, making it suitable for weight sensitive applications. The silicon optics are available with a 3-5μm BBAR coating in a range of sizes. The lenses and windows feature precision polished surfaces for IR applications including IR spectroscopy.

TechSpec germanium windows and PCX lenses are available with 3-12μm and 8-12μm BBAR coatings for use in IR applications that require rugged optics. Germanium is a durable material, which is inert to air, water, alkalis and most acids. The germanium lenses offer minimal chromatic aberration due to low dispersion, making them suitable for applications such as thermal imaging, IR spectroscopy and remote sensing.
