3D Upgrade for Optical Microscopes

In conventional microscopic images of materials and life cells, only object intensity and color are imaged. However, the phase of the light beam bears information about the 3D structure of the object with which the light interacted. The Digital Phase Technology developed by PhaseView in France allows upgrading conventional microscopes to transform them into a 3D measurement device with vertical resolution in the nanometer range. The upgrade is a device which goes onto the C-mount of the microscope. moreOct. 12, 2009

Ca2+ Imaging

Effective fluorescence imaging of Ca2+ signals requires special filters for excitation of Fura 2 in UV at 340 nm and 380 nm. New hardcoated exciters with 95% transmission for ratio measurements are now available from AHF analysentechnik. Also emission filters with more than 95% transmission will enable maximum of signal intensity. Combining of GFP excitation and Fura 2 imaging can be done as well by using special filter set-ups. These filters can be mounted in all the different cubes of microscopes. moreOct. 12, 2009

Nanometer Precision

The Rowiak CellSurgeon is a laser nanodissection system for gentle manipulation of living cells and subcellular structures. It combines microscopic imaging techniques with femtosecond laser cutting, providing a versatile platform for novel experimental approaches in biological, medical and pharmaceutical research. Applications include, for example, transfection of cells, deactivation of cell organelles or investigation of cell dynamics. moreOct. 12, 2009

3D Imaging

Hyphenated Systems, a world-wide provider of hybrid microscopy solutions for three-dimensional imaging and metrology in micro and nanotechnology, announced the release of its HS200A NanoScale Optical Profiler. The HS200A adds extensive automation capability to the companys workhorse the HS200OP for most repeatable non-destructive analyses in critical metrology, inspection, failure analysis and quality control applications. moreOct. 12, 2009

High End Optical Filters for Biophysics

Single molecule experiments, multiphoton spectroscopy or TIRF microscopy require optical filters perfectly matched to the corresponding laser lines.
Clean-up filters, dichroics and emitters for solid laser, gas lasers and laserdiodes made with high end optical filter technology will be offered from AHF analysentechnik AG. The company will offer best support for optimizing complex spectroscopic setups with the long time experience in specifying filter components. New products for multiline laser applications offer new chances. moreOct. 12, 2009

Pelco BioWave Pro

True variable wattage control and the unique new Pelco Coldspot are integrated in the new Pelco BioWave Pro microwave tissue processing system. Standard protocols are already programmed in the system with full editing facilities for additional protocols. Remote access allows protocol monitoring from any location. moreOct. 12, 2009

Optical Quality Control on Surfaces

Surfaces differ in roughness, reflectivity, form, planarity and other parameters. In order to be able to measure a wide variety of samples, Sensofar PLµ 2300 incorporates the measurement modes interferometry as well as confocal. To measure the roughness of a very smooth surface is as easy as measuring the form of a part with steep flanks. The sensor head may be configured for the use as tabletop instrument, attached to a robot arm or as portable system to measure large samples. moreOct. 12, 2009

Electron Multiplier Camera

The EM-CCD camera model C9100-02 by Hamamatsu Photonics allows for 2000 fold signal amplification by improved on chip electronics. The frame transfer CCD chip features 1000 x 1000 pixels resolution. Due to the frame rate of more than 30 Hz in full resolution this camera is especially suited for imaging quick moving objects. The readout noise is less than one electron (rms) at 14 bit signal depth. Thus extremely low signals can be reliably detected and displayed with high image quality. more
