Single and Double-sided Optical Flats
dual-surface optical flats are an excellent choice when an optical system requires separation between two environments while passing a specific wavelength(s) of light or for demanding interferometry requirements. Optical Flat Refinishing. Advanced Optics provides optical flat refinishing services with fast turn-around time. Optical flats and windows become worn and abraded in use and accuracy is lost. This degradation in performance is due to a decrease in the distinctness of the interference... (read more)

Dynamic Interferometry: Getting Rid of the Jitters
Conditions on the factory floor and in industrial cleanrooms with high-capacity air filtration systems can hamper the use of interferometry. Another problem is the testing of large-aperture mirrors where it is difficult to mechanically isolate them and the structures needed to support the optical
Improved Interferometric Optical Testing
Interferometry is used for testing optical components and optical systems as well as the metrology of many other components, such as the flatness and roughness of hard disk drive platters and the shape of magnetic recording heads and machined parts. This article describes three recent advances
Dynamic Interferometry Handles Vibration
is the testing of large-aperture mirrors (1-10 m) when it is difficult to mechanically isolate such mirrors and the structures needed to support the optical test; in addition, long optical paths produce air-turbulence problems. To make things worse, the next generation of large-aperture lightweight mirrors
Spatial Coherence in Interferometry

That important invention facilitated the production of high accuracy optical parts worldwide in the past three decades. Among the challenges of today
Optical Metrology for Large Telescope Optics
In recent years the demand for meter-scale optical elements has increased significantly, driven by growth in terrestrial and satellite-based astronomy, and defense and security applications. Laser interferometry is used throughout the manufacturing of large optics to ensure conformance to demanding
Optical Strain Gauges
There are three types of optical strain gauges: photoelastic, Moire interferometry, and holographic interferometry. Photoelastic strain gauges subject an elastomeric material to a load and illuminate the material with polarized light from the measurement instrumentation, a reflection polariscope
Watch and Clock Part Surface Quality Depends on White-light Interferometry (.pdf)
Optical metrology is gaining in importance for quality assurance of precision micro-parts. Fast, high resolution measurements using a non-contact, non-reactive (zero mass loading) optical technique are particularly appealing for micro-parts. By reviewing an application from the watch
