Optical Windows and Mirrors


Even the most complex optical systems require optics serving the primary function of a window or a mirror.  Windows are often used as the final optical component of an optical system or photonics device (think of the screen or camera lens on your smartphone for example).  Windows also can act as a “shield” against the harmful environment that could otherwise expose an optical system.  Basic mirrors with the purpose of reflecting light are equally (if not more) critical (think of mirrors in a basic periscope for example).  A telescope would not be a telescope without mirrors.

Precision Optical has capacity to handle the most demanding requirements for optical windows and mirrors.  From small plano/parallel windows, to high-powered laser line mirrors to large interferometer flats, our experienced technicians produce optical windows and mirror with superior flatness, transmitted wavefront, parallelism/wedge and mechanical dimensions, with minimal cosmetic surface defects.

Our coating chambers can be configured to handle optical windows and mirrors ranging in size from 3mm to 660mm. Coating capabilities include laser line, broadband and multi-band anti-reflection coatings, dielectric mirrors with high laser damage resistance, and plasma or ion enhanced dielectric coatings with excellent thermal stability. We also offer protected/enhanced aluminum and silver mirror coatings and neutral density filters.

Precision Optical’s array of state-of-the-art metrology equipment, such as advanced phase-shifting interferometers, dynamic interferometers, and large aperture beam expanders, allow precise measuring of optical windows and mirrors of all shapes and sizes.

    Partnering with Precision Optical through their Ensign-Lambert Optics Education Program has allowed over 120 of my laser and optical technology students to gain real-world perspective with hands-on work in optics. These interactions directly motivate the next generation of technicians as they learn first-hand how this fascinating work with industrial hardware will translate into rewarding careers.
