• Industrial Laser Mount Eliminates Shifts During Shipping

    by | Dec 18, 2017

    As Published in Novus Light

    Lee Laser (now part of Coherent) built a successful business featuring lamp-pumped and then diode-pumped (i.e., DPSS) solid state lasers, with powers up to 100 watts.  In a field with multiple low-cost competitors, Lee Laser was able to effectively differentiate their brand as a supplier of affordable industrial lasers featuring “workhorse” reliability. Prior to the company’s acquisition by Coherent, Lee saw this brand image threatened when some of their side-pumped DPSS lasers failed to work to specification when received by the customer.  Because of the importance of reliability to their industrial customers and to Lee’s market leadership, the company set out to identify and eradicate the source(s) of these failures.  (read more ....)

    48220000Imaging transparent, colorless specimens has always presented a challenge in optical microscopy. In many applications, it is not desirable or even possible to use fluorescent dyes, stains or transgenic probes to render target objects more visible.  While differential image contrast (DIC), often in the form of the Nomarski microscope, is widely employed, its optical complexity can cause limitations when the contrast image is combined with some other measurement modality or imaging technique (such as patch-clamp measurements or optogenetic stimulation, or even simply epi-fluorescence).....

  • Neuroscience Under the Microscope | Published Article from Novus Light

    by Michael O'Coyne | Aug 15, 2017

    NovusLight-figure-1While optical microscopy methods for neuroscience have expanded significantly in recent times, traditional tools such as patch clamp technology are still widely used because they provide superior data for many types of experiments. Researchers at the AstraZeneca-Tufts Laboratory for Basic and Translational Research are using patch clamp technology to study fundamental aspects of synaptic inhibition that are associated with epileptic-type seizures. This Institute itself is an exciting new business model in the world of neuroscience research, created as a joint collaborative venture between a leading academic institution and a highly respected pharmaceutical giant.

  • Ultra-stable micromanipulators, as seen in Laser Focus World

    by Michael O'Coyne | Oct 04, 2016
    Among the DC/servo options, the MX7000 series demonstrated the lowest amount of play and drift compatible with MyoStretcher’s target performance (measurement to 1 nN), while providing up to 20 mm of motion in each axis. A motorized actuator with anti-backlash gear-head (in each axis), driving a crossed roller-bearing highly linear stage, eliminates axial and lateral play, and a pre-loaded screw drive avoids the possibility of drift when stationary—that is, during a typical single myocyte experiment. Also, because the three-axis subsystems were originally developed for demanding electrophysiology (patch clamp) experiments, they are totally compatible with the limited access of a high-magnification optical microscope.  (read more...)
