      Optimizing Probe Positioning for Life Science Research

      by John Wingerd | November 2018

      Photonics technologies enable life scientists to probe samples in the increasingly sophisticated study of processes ranging from neuron signaling to heart muscle contraction, as well
      as cells and cellular development. As research continues at increasingly finer levels of resolution, the requirements for optomechanical positioning become ever more demanding.
      ? ? Positioning equipment manipulates the probes used to interact with biological samples. This includes positioning a light probe, such as a focused laser or LED, and positioning a physical
      probe, such as an electrode or microsyringe.

      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.?

      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).....

      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...)
