Optical Windows

Thin-Film Coating Equipment for Precision Optical Components

Optical windows transmit specific wavelengths of light for opto‑electronic systems while shielding them from environmental influences. They are used in the aerospace industry for applications such as earth observation, remote sensing, environmental monitoring, altitude and distance measurement, LiDAR, radar, camera sensors, pilot vision systems for collision avoidance, and in communication systems. This makes optical windows mission-critical for manned and unmanned aerospace applications.

Their shape and size can vary widely, though they are often flat glass plates optimized for maximum transmission with antireflective (AR) coatings on both sides.

The OPTA X is designed precisely for these requirements. The PVD coating system accommodates a wide range of substrate geometries and enables fast, simultaneous AR coating of both surfaces, as well as the deposition of selective interference filters. The resulting layers offer high durability, with strong resistance to climate effects and abrasion.

In ad­di­tion, it of­fers the pos­si­bil­i­ty of si­mul­ta­ne­ous and fast an­ti-re­flec­tion coat­ing of front and back sides and the de­po­si­tion of se­lec­tive in­ter­fer­ence fil­ters. The de­pos­it­ed lay­ers are cli­mate-re­sis­tant and abra­sion-re­sis­tant.

Fur­ther­more, you can use the OPTA X to de­pos­it trans­par­ent con­duc­tive ITO lay­ers—ei­ther as a top lay­er or with­in the mul­ti­lay­er stack.
