WaveMaster® PRO and PRO Wafer have
been designed to meet the requirements
for high volume
production testing
of imaging systems,
single lenses
or lenses on
wafers.
The instruments
provide an accurate,
reliable and
fast way for automatic
production
testing. With the
combination of a
fast, high accuracy
wavefront sensor
and special
positioning algorithms a high throughput is
achieved.
WaveMaster® PRO comes with a tray
system in which a high number of single
lenses is arranged. In contrast to WaveMaster® PRO, the WaveMaster® PRO Wafer
comprises of a special tray system for
wafers with a diameter of up to 12 inch
and an additional tool which determines
the wafer orientation in the instrument. The
tray systems of both instruments allow for
fully automatic positioning of the lenses
during the measurement process.
WaveMaster® PRO and PRO Wafer provide
lateral resolved information from design or
reference data, scratches and lens impurities
within a measurement time of less
than three seconds for each single lens
under test. This allows for direct feedback
into the large volume production process.
The production software enhances the capabilities of all WaveMaster® PRO instruments
proving production specific features
like pass / fail classification.
Advantages of WaveMaster® PRO and
PRO Wafer
- High throughput due to high measurement
speed and fully automatic batch
wise or wafer measurement
- High spatial resolution for extremely accurate
measurements
- Point light sources with different numerical
apertures (up to NA 0.95) and working
distances
- Easy loading due to kinematic mount
- Automatic, high precision linear positioning
- Measurement either relative or absolute,
allows for comparison with a
master lens or design data
- Maximum utilization of the sensor dynamic
range with a set of telescopes
- Full functionality of wavefront analysis
and detailed analysis of single lenses
and wafer lenses
- Production software module, for example
with export of pass/fail matrix for use
in adjacent production line machines
- Robust and vibration insensitive main
frame
- Flange focal length measurement (FFL)
- Wafer bow compensation
- Wafer orientation measurement tool
