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.
Applicable model:All models
A measuring point is magnified for display to enable easy positioning.
Wafer level lens (WLL)
*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 (Φ30 µm - Φ300 µm) may require an observation camera for measurement.
◆ Special stylus is available as an option subject to discussion.
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.
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.
Applicable model:All models except for UA3P-400T
Fully automated, including probe movement and focus ON/OFF
Supporting various errors
* The jig is prepared by the user
