BioPhase: provides in-situ stain free cell monitoring using brightfield objectives
BioPhase is an imaging device from PhaseView with unique capability of simultaneous acquisition of intensity and phase data at ultra high resolution, providing qualitative cell imaging and accurate quantitative measurements with outstanding key benefits.
Time lapse monitoring of 3D cell morphology can be performed without contrast agents with related photo toxicity and without specialized optics for free space manipulation. Cells can remain in situ in their growth medium using standard incubation flasks, Petri dishes or multi well plates.
The smart BioPhase camera is compatible with any optical microscope equipped with a video port and standard brightfield objectives. In addition fluorescence, confocal or TIRF images can be acquired using the same objective as well as providing simultaneously phase contrast imaging.
Unlike DIC or Phase Contrast techniques with halo or gradient side effects, BioPhase delivers true quantitative phase data for counting or volume measurements.
Ellipsometry is a versatile and powerful optical technique for the characterisation of thin films in a very wide variety of contexts and applications. It works by measuring the change in the state of polarisation of light reflected off the surface of the film. Its extremely high sensitivity makes it an unequalled tool for the metrology of thin film surfaces. Lastek offers a selection of ellipsometers, from Nanofilm.
Ames Photonics have launched an all-new website describing their extensive range of modular tools for spectroscopy.
Ames has been producing high quality CCD detectors since 1996. Their products are widely used in a broad range of applications including pulsed and ultrafast laser spectroscopy. Since then they have also evolved a suite of complementary products which make it possible for spectroscopists to assemble cost-effective complete systems from a wide range of interchangeable components, including visible and near-infrared detectors, advanced control software, hardware interfaces and instument integation. The new site includes details of their LARRY and GARRY series of linear CCD detectors, and their extensive range of innovative spectroscopic components and instruments. The recently releseased Oculus USB plug-n-play photodetector and the MMULS Multifunction Ultrafast Spectrometer are also both described in detail.
As a laser vendor, we should be supressing this information, but it's so cool we can't help share it. Here's an excellent article explaining how to create hand-made holograms with just a few simple tools. No laser required! Amazing.

Lastek is delighted to be appointed Australian/New Zealand distributors for PhaseView, the Digital Wavefront Company. PhaseView offers high precision, easy to use, and cost-efective standalone and OEM 3D optical measurement instruments and non-destructive solutions for quality control, life sciences, photonics and defence. Their range of products falls in two broad categories: 3D surface metrology and Wavefront Sensing. Applications in surface metrology include semiconductors, photovoltaics, and metal/polymer finishes. In the field of wavefront sensing, applications include wavefront analysis, lens testing, laser characterisation and ophthalmology. Contact Lastek to discuss how PhaseView systems can assist with your specific metrology problem.
LaVision and Lastek will be exhibiting at the upcoming 8th International Symposium on Particle Image Velocimetry, to be held at Monash University, Melbourne, from August 25 - 28. We extend an invitation to visit us at the Trade Exhibition to see the range of state-of-the-art PIV systems offered by LaVision. We will also be conducting a series of on-site customer demonstrations either side of the conference dates throughout Australia. If you would like the opportunity to see the benefits of LaVision technology first-hand in your laboratory or facility, please contact Anthony Quinn at Lastek to arrange a visit. Also, please see our extensive webpages describing the complete range of flow visualisation systems available from LaVision here. We look forward to seeing you at PIV09 in Melbourne this August.
These versatile systems have been developed for measuring and logging CW and pulsed optical and laser sources in the 200-1700nm range. All operating parameters (integration time, interval between samples, averaging, internal delay and box-car mode operation) are controlled via open -source software. Each detector is supplied with a Software Development Kit containing examples of typical detector acquisition and display programs in Labview, C++, VB and SpectraScript. These examples can be used to make simple measurements. Source code is included, enabling users to extend these programs or write completely new ones to control the detectors and integrate them into larger experiments.
The detectors incorporate low noise, high gain 16 bit oversampling amplifiers for high sensitivity. Typical saturation signals are a few nJ. The shortest integration time is 20 microseconds, the longest 10 seconds. The detectors incorporate an external trigger input and internal, programmable delay generator for synchronization to pulsed sources.
