Taylor Hobson LUPHOScan 75 HD Non-contact 3D Optical Form Measuring System

Unique benefits for both design and production

Automatically align optics - In as little as 45 seconds*

Faster measurement cycles with the Focal Point Pivot (FPP) technology - Up to 65% reduction in time*

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 - Interlocks and edge diameters in relation to each other or the optical surface

LUPHOScan 75 HD - Align, measure, analyse in <120 seconds

The world’s fastest and most accurate automated system, for non-contact 3D small lens metrology.

The LUPHOScan 75 HD brings laboratory level accuracy to high volume production. Consistently accurate results are achieved with a single click, enabling operators of any level to deliver fast detailed analysis.

Measurement principle

During measurement the probe performs a spiral scan over the entire surface of the object under test and produces high density 3D data. Scanning is achieved by rotating the object by means of an air-bearing spindle whilst the sensor is moved radially and axially using linear stages.

A rotary stage keeps the sensor normal to the object surface. The layout of movement stages provides high flexibility, even for uncommon surface shapes including steep slopes or profiles with points of inflection.

Optimised LUPHOScan probe

The new probe technology used on the LUPHOScan 75 HD adds additional benefits including an increased working distance of 7.5 mm. This enables complex geometric features on lens moulds and moulded lenses to be measured, such as:

Thin transparent substrates - Access to measure interlocks without collision between the probe and substrate.

Fast measurement speeds for true 3D - Increased access to steep concave optical surfaces

Accuracy through automation

The New LUPHOScan 75 HD provides complete instrument automation with the introduction of the fully automatic centring and levelling table.

‘Single Click’ align, measure and analyse

Increase throughput with shorter setup time

Remove operator skill dependence

Measurement consistency through automatic reproducible centring and levelling
