OptiSurf®
Bridging the gap
High-precision centration test devices, alignment, cementing and bonding systems.
OptiSurf® is ideal for the non-contact measurement of the center thicknesses of single lenses and plano optics as well as for the measurement of air gaps in optical systems. The low-coherence interferometer measures all surface distances in an optical system in just one scanning operation and with an accuracy of up to 0.15 µm. Its innovative alignment, adjustable sample tray and intuitive software ensure the exact positioning and measurement of lenses and optical systems in the easiest way possible. This makes OptiSurf® particularly suitable for use in production.

OptiSurf® LTM details
High precision center thickness and sag value measurement of single lenses and doublets.
In optics production, the high quality of the single lens is the prerequisite for high-precision optical
systems. With the OptiSurf® LTM (Lens Thickness Measurement), TRIOPTICS offers a precise center
thickness measurement system for single lenses and doublets that seamlessly integrates into any
production process. The high precision low-coherence interferometry is based on the established
OptiSurf® technology and measures single lenses and doubles with a glass thickness of up to 150 mm
with a precision of ±0,5 µm. The non-contact measurement system is gentle on sensitive surfaces
and coatings. In addition to the center thickness, the sag value can also be determined.
