Shop Floor Measurement

Quality assurance measurements for optical grade surfaces have traditionally been made in a tightly controlled quality control lab, with vibration isolation tables, expensive air handling equipment and careful temperature control. This approach has many drawbacks: it increases part handling, which wastes resources and risks damage; it requires significant investment in facilities to accommodate often delicate equipment; and, perhaps most important, it separates the measurement feedback from the processes on the shop floor.

Instantaneous laser interferometer measurement, made possible through 4D’s Dynamic Interferometry®technology, brings measurement right to the optical shop floor, despite vibration and turbulence. Production floor measurement saves handling time and reduces the risk of damage to optics during handling, for highly efficient process control and quality verification. 4D Technology’s Fizeau, and Twyman-Green laser interferometers, and NanoCam Sq optical profilers,

 4D Technology’s dynamic, high-speed measurement technology–in FizCam Fizeau interferometers, PhaseCam Twyman-Green laser interferometers, and NanoCam Sq optical profilers–provides shop-floor measurement of optical surface shape, roughness, and transmitted wavefront.

The unique  4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact measurement of surface features and defects, on the factory floor, in machine shops and in field service applications.
