Optical Gaging Products Inc. (OGP) offers its new “specialist” dimensional measurement/inspection systems—the SmartScope Specialist 300 multisensor dimensional measurement system and the Focus Specialist 16" horizontal contour projector for the medical industry. These systems were specifically designed to verify critical dimensions of orthopedic implants such as intervertebral disc spacers and artificial discs; the stem, ball and cup of prosthetic ball joints; tibial and femoral knee implants; and tibial and talar ankle implants; as well as syringe components and fluid flow components.

The measurement system is an optical-based benchtop metrology system offering micron-level measurements within a 300 x 300 x 250 mm (12 x 12 x 10") XYZ measurement volume. This machine verifies critical dimensions of a range of medical parts. A measurement routine for one part is easily repeated for a batch of fixtured parts, providing throughput to support production requirements.

Focus Specialist is a premium benchtop optical comparator contains completely telecentric optics that yield upright and reversed images that are crystal-clear and undistorted. Its dedicated 5× lens allows 3.2" of a part to fill its evenly illuminated 16" (406-mm) diameter screen—more than could be seen on a 30" comparator using a 10× lens. With new eCAD, a CAD model presents a virtual chart on the Focus screen, essentially eliminating traditional overlay charts. The 5× lens and CAD-generated charts make the comparator perfect for non-contact visual inspection/measurement of medical parts.

The comparator features all-LED TruLight illumination. It is equipped with a high-brightness monochromatic green LED profile light, while a white LED TTL coaxial surface light provides surface illumination, the company says. Unlike older light sources, TruLight LED illumination intensity is variable. Long-lived, they provide years of service, while consuming a fraction of the energy and producing much less heat than traditional tungsten illumination.
