Software
Circumferential scanning measurement software
The measured object is circumferentially scanned and measured.
· Hollow objects are also measureable.
· Up to 1200 concentric circles.

User-defined software (free-form curved surfaces, etc.)
Other formulae are supported in addition to the lens design formula that is registered as a standard feature.
The use of the C language for creating the design formula and the calculation part of a partial differential equation allows all of ISO10110-12 to be covered.

* Limited to the case that can be expressed by applicable Z = f (x, y).
Software for creating point group data design formula
A rectangular curved surface is created using the spline function with respect to given 3D point group data.

Fitting software (rotation symmetry)
A previously unknown design formula of a measured object can be obtained from the measurement data.

Auto-measurement
Applicable model: All models except for UA3P-400T

Fully automated, including probe movement and focus ON/OFF
Supporting various errors

Hardware
Stylus
New diamond stylus for top-surface measurement
Supports precise shape measurement, such as of mobile lenses and diffracting gratings

Ruby stylus for top-surface measurement*1
Uses a high-sphericity ruby ball for general-purpose measurements

Stylus for side-surface measurement*2
Super-steel or ruby available for the tip.

Decenter and Tilt measurement jig
Decenter/Tilt measurement between lens faces
The lens is fixed on a jig provided with three reference balls for combination. Any decentering between the lens faces is evaluated by measuring both faces of the lens.

Aspherical face - Aspherical face lens

Example of evaluation of lens decenterand tilt

* Precautions
*1 Note that the ruby stylus is at risk of breaking due to its large coefficient of friction while measuring aluminum lenses or surface-coated lenses.
*2 The stylus for side-surface measurement (ø30 µm - ø300 µm) may require an observation camera for measurement.
For other kinds of parts (stylus length, tip size or material), please ask at our sales office about the detail.
