LUPHOScan 50 SL - Taylor Hobson
LUPHOScan 50 SL ultra fast non-contact, 3D Lens Form/Shape Measuring Instrument
The LUPHOScan 50 SL is ideal for high volume production of small lenses with key benefits of the system including ultra fast measurement speeds and the ability to measure geometric lens features. It can measure the optical surface and geometrical features such as interlock surface roundness, flatness of the flat lens surface and location of the optical surface relative to these features.
Unique benefits for both design and production
- Ultra high, repeatable accuracy – 30 nm PV (3σ)
- Best available stability – Power variation < ± 15 nm (3σ), PV variation < ± 1.5 nm (3σ)
- Analyse geometric features – Such as interlocks and edge diameters in relation to each other or the optical surface
- Thin transparent substrates – Down to 100 μm thickness
- Fast measurement speeds for true 3D – < 120 sec. – Optical surface and geometric features*, < 60 sec. – Optical surface only**.
Critical measurements for design and production:
- Investigation of any rotationally symmetric surface (aspherical, spherical, planar and light freeform)
- Very high accuracy (≤ ± 50 nm)
- All materials: transparent, specular, opaque, polished, ground
- Very flexible: measures interrupted surfaces, circular optics, rectangular surfaces, surfaces with diffractive structures, axicons
- Complete lens characterization: thickness, centering error, lens holder positioning.
