Edmund Optics IR optics featuring BBAR coatings

Edmund Optics introduces an expanded offering of off-the-shelf infrared (IR) optics featuring broadband antireflective (BBAR) coatings. These include 3-5 μm coating options on Silicon PCX Lenses and Silicon Windows and 8-12 μm coating options on Germanium PCX Lenses and Germanium Windows.

Techspec Silicon (Si) Windows and PCX Lenses are manufactured from optical-grade silicon, which is characterised by a low density of 2.329 g/cm³, making it suitable for weight-sensitive applications. Techspec Silicon optics are available with a 3-5 μm BBAR coating in a range of sizes. The lenses and windows feature precision polished surfaces, suitable for a variety of IR applications including IR spectroscopy.

Techspec Germanium Windows and PCX Lenses are available with 3-12 and 8-12 μm BBAR coatings and are suitable for use in IR applications that require rugged optics. Germanium is a durable material which is inert to air, water, alkalis and most acids. Techspec Germanium Lenses offer minimal chromatic aberration due to low dispersion. The optics are suitable for a variety of IR applications, including thermal imaging, IR spectroscopy and remote sensing, and are available in a range of sizes.

The company offers over 650 stock IR optic designs on a range of substrates, including calcium fluoride (CaF₂), UV fused silica, germanium (Ge), sapphire, silicon (Si), zinc selenide (ZnSe) or zinc sulfide (ZnS). Additionally, Edmund Optics offers quick modifications to stock components to take the user’s project from design to prototype to volume production.
