VICTOR, N.Y., July 1, 2016 —

Micropositioning stage developer New Scale Technologies Inc. has moved its miniature Cobra fiber positioners into full production, manufacturing 200 units per month for the Subaru Telescope Prime Focus Spectrograph.

New Scale Technologies has achieved full-scale production of 200 Cobra positioners per month at its advanced manufacturing center near Rochester, N.Y.

New Scale will deliver a total of 2,550 Cobra positioners to the California Institute of Technology by June 2017. Deployed in a close-packed array, the Cobra positioners rapidly configure an array of fibers in the prime focus of the telescope to a precision of 5 μm. They enable the Subaru Telescope to conduct a variety of targeted surveys for studies of dark energy, galaxy evolution and galactic archaeology.

This production milestone was reached after eight years of research and development.

New Scale is a developer of closed-loop positioning solutions.




GLOSSARY
telescope
An afocal optical device made up of lenses or mirrors, usually with a magnification greater than unity, that renders distant objects more distinct, by enlarging their images on the retina.
spectrograph
An optical instrument for forming the spectrum of a light source and recording it on a film. The dispersing medium may be a prism or a diffraction grating. A concave grating requires no other means to form a sharp image of the slit on the film, but a plane grating or a prism requires auxiliary lenses or concave mirrors to act as image-forming means in addition to the dispersing element. Refracting prisms can be used only in parallel light, so a collimating lens is required before the prism and...
astronomy
The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
