HardZap™ Beryllium Optics are used in scanning, night vision and other applications. These mirrors are made of bare-polished beryllium metal (i.e. no electroless nickel coating) and so do not exhibit the bi-metallic problems associated with the traditional electroless nickel coated beryllium mirrors. Their light weight, extreme stiffness, and excellent heat tolerance have made them a standard for fast and highly accurate scanning systems.

HardZap mirrors can be coated with a variety of evaporated coatings to provide/enhance reflectivity at most wavelengths in the IR, visible and UV.


Capabilities:

FLATNESS: We have achieved better than 1/10 lambda at 633 nm. However, our ability to achieve this depends on the mirror size and design. So specify only the flatness your application requires.

SURFACE FINISH: Depending on the size of the mirror, we have achieved better than 15 Angstroms RMS on the bare beryllium. If you need this fine a finish, review your mirror design with our engineering staff.

MIRROR SIZE: Up to 18 in. (45.7 cm) across.

COATINGS: Our standard coatings are gold, enhanced gold, silver, enhanced silver (Request our reflectivity chart). Coatings for use with high-power CO2 and YAG lasers are available. Other coatings on request.
