In-Situ Nanomechanical Testing Mini Symposium
Tuesday and Wednesday 1 & 2 June 2021, 8:30pm AEST
Probing the mechanical behaviour of materials at the nanoscale is necessary for the development of new nanostructured materials and continued miniaturization of engineering devices, electronic components, thin films, and surface coatings. This symposium will cover state of the art topics related to cutting edge developments in nanoscale mechanical characterization of materials such as metals, alloys, ceramics and organic crystals. The talks will demonstrate in-situ nano-mechanical testing techniques to extract site specific properties across temperatures and environments in a high throughput manner as well as introduce data science approaches for the same. The lecture themes are relevant to both audiences from academia and industry.Read More
AX AXR Confocal Microscope
Nikon Corporation (Nikon) is pleased to announce the release of the next generation confocal microscope series, AX and AX R. This new confocal series features a completely re-designed scan head with 8K x 8K resolution*1, ultra-high speed resonant scanning, and world’s largest*2 25 mm field of view*3. Combined with a new user-friendly interface and advanced AI-based tools, the AX/AX R confocal series is designed to enable users to acquire data faster, with an unprecedented level of detail and ease.
1. Capture more data than ever before with 8K x 8K pixel density and a 25 mm field of view
The AX and AX R enables 8192 x 8192 pixel, high-resolution images to be obtained with the world’s largest field of view (25 mm). Now, ultrafine details can be easily captured even for large specimens. This feature is available for both inverted*4 and upright*5 microscope configurations, thereby supporting a wide range of research applications and fields.
In addition, with the AX R’s high-speed resonant scanner users can acquire up to 720 frames per second at 2048 x 16 pixels. High-speed resonant scanning not only enables dynamic events to be easily captured but also reduces the amount of time required to image large, fixed specimens.

With high-speed scanning, it is possible to minimise photobleaching of the specimen even with long-term imaging.
2. Improved specimen viability for longer time-lapse imaging
The AX/AX R features detector units that are twice as sensitive as conventional models*6, with a ~30% reduction in dark current noise*7. With increased sensitivity and reduced noise, lower illumination power can be used for imaging even dim specimens, minimizing photobleaching and phototoxicity. Combined with high-speed resonant scanning which further decreases exposure time, specimen viability is greatly extended, enabling extreme, long-term time-lapse imaging.
3. A simplified, AI-driven user experience
Nikon’s NIS-Elements C imaging software allows users to easily customize the layout and experiment workflow to suit their needs. The new Autosignal.ai tool simplifies confocal acquisition by automatically determining the optimal illumination and detection settings while Denoise.ai removes shot noise from confocal images to enable clearer images with shorter exposure times. AI-based tools for post-acquisition image processing such as Segment.ai makes segmentation of complex structures more efficient and reliable.
Graphical programming tools for both acquisition and analysis provide further flexibility for the user. The optional JOBS module enables complex, non-linear experiments with multiple paths and dimensions to be created with ease, including conditional workflows where subsequent acquisition parameters are based on real-time analysis results.

The new HASO LIFT wavefront sensors from Imagine Optic combine a high-resolution mode with all the benefits that make Shack-Hartmann one of the most relied-upon technologies in optical metrology. This new series embeds a fully revamped Waveview4, including the absolute tilt measurement SpotTracker technology and numeours other options.
The HASO LIFT 272 is the HR version and features 272x200 phase-points resolution as well as the new SpotTracker technology.
The HASO LIFT 680 combines the highest resolution in Shack-Hartmann technlogy and a very large dynamic range.
Synchronous Source Measurement System
The new MeasureReady M81-SSM (Synchronous Source and Measure) system from LakeShore provides a confident and straightforward approach for advanced measurement applications. The M81 is designed to eliminate the complexity of multiple function-specific instrumentation setups combining the convenience of DC and AC sourcing with DC and AC measurement, including a lock-in's sensitivity and measurement performance.
This extremely low noise simultaneous source and measure system ensures inherently synchronised measurements from 1 to 3 source channels and from 1 to 3 measure channles per half-rack instrument - while also being highly adaptable for a range of material and device research applications.Read More
Fixed Wavelength Femtosecond Laser
Coherent Inc introduces Axon 780, the newest wavelegnth in the Axon line of compact, discrete wavelength femtosecond sources.
Axon demonstrates market leading performance and features in the same form factor as other Axon lasers, enabling plug-and-play compatibility between wavelengths at the same competitive price point. Like other Axon lasers at 920nm and 1064nm, it is perfect for 2-Photon imaging applications, especially for label free and clinical pathways. It is also ideal for a variety of other applications in nanofabrication, metrology and terahertz spectroscopy.
