Title
A New Single-control Micromanipulator
Description
Article in Quarterly Journal of Microscopical Science, vol 89 series 3 no. 8, describing a micromanipulator invented by the authors.
Summary:
New developments in miscroscopy and electrophysiology have brought a renewal of increase in methods of micromanipulation.
A number of features desirable in the design of a micromanipulator is discussed.
A new micromanipulator is described. Its outstanding features are 1) single control; 2) massive construction with freedom from vibration; 3) freedom from play; 4) continuous variability of sensitivity; 5) limitation of range of movement to the field of view; 6) rapid low-power centring; 7) unusual robustness combined with delicacy of movement achieved without any high-precision methods. The performance of the instrument is adequate for high-power cytological work and for micro-dissection by phase-contrast illumination.
