HEIDENHAIN Gauge Facilitates Precision Stereology Research

Stereology, a tool that became popular in the late ‘90s, is used to quantify properties of 3D objects from 2D sections through an object (such as microscope slides of brain tissue). This method is accepted by neuroscientists as the preferred way to estimate numbers of cell populations in brain structures. The MBF Bioscience’s Stereo Investigator system from MBF Bioscience, Williston, VT, is the market’s leading product and utilizes procedures that use small sample sizes that can be collected rapidly and assure findings that will be accurate, unbiased and statistically efficient.

Magnetic Rotary Encoders Aid Remote Control Vehicle

AB Precision (ABP) prefers to call its Guardian a vehicle (as in MROV - Miniature Remotely Operated Vehicle) rather than a robot. Names aside, the UK-based engineering company’s quadtracked, articulated creation is characterized by dexterity and maneuverability. Its network of ten Renishaw non-contact encoders provide absolute positional feedback to a CPU.

Choosing Optics for Medical Lasers

Designers of medical equipment using lasers must be careful in their selection of optical components in order to ensure safe and reliable operation. The high power density and narrow wavelength range of lasers create problems not found in other medical optics such as microscopes and cameras. Proper selection of materials, manufacturing specifications, and coatings becomes essential to avoid such problems.

Micro-Molded Spacers Protect Thermal Insulation of Cryogenic Propellants

Micro-Molded IMLI Matrix part Phillips Plastics Corp. Prescott, WI 877-508-0252 http://phillipsplastics.com

To achieve a high level of energy density as well as green environmental performance and safety, NASA prefers to use cryogenic propellants such as liquid oxygen, hydrogen, and methane to propel their spacecraft. However, these propellants are at very cold temperatures, as low as -423°F, and must be stored in thermally insulated tanks to keep the contents from boiling off. Next-generation NASA exploration missions will require spacecraft such as the Altair Lunar Lander to maintain cryogenic propellants for up to six months.

Lenses Monitor Hubble Space Telescope Servicing in Orbit

C-mount Xenoplan and Cinegon lenses Schneider Optics Van Nuys, CA 818-766-3715 www.schneideroptics.com

Schneider Optics’ C-mount Xenoplan and Cinegon lenses were selected by NASA to monitor aspects of the recent Hubble Space Telescope servicing mission. During the rendezvous between the shuttle Atlantis and the Hubble Space Telescope, and thereafter — while seven astronauts replaced six gyroscopes, batteries, and a sensor used to guide the telescope — the lenses were the “eyes” of the cameras that delivered high-resolution images to the shuttle and to engineers on Earth.

Disk Lasers in the Photovoltaic Industry

Diverse types of lasers, such as nanosecond, pulsed, and excimer, have been considered for various applications in the photovoltaic industry, including edge isolation, edge deletion, drilling for back contact, cutting of Si-wafer, and patterning of crystalline solar cells. High power lasers, with high stability and high efficiency in addition to high beam quality, are needed now more than ever.

Assembly Machines Produce Optics for NASA’s NuSTAR Telescope

Cylindrical optics module assembly machines ABTech Swanzey, NH 603-358-6431 www.abtechmfg.com

ABTech has completed the first of two cylindrical optics module assembly machines for Columbia University’s Nevis Astrophysics Laboratory. The multi-axis air bearing machine platforms are optimized for the construction of high-energy xray telescopes. The optics modules will be used to produce the telescope optics for NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) program. ABTech will provide installation and on-sight operational training to Columbia University scientists at the Nevis Laboratory and ongoing technical support during the production of the optics modules.

CCD Imaging Sensors Aid Hubble in Exploring the Universe

Charge coupled device (CCD) imaging sensors e2v Chelmsford, UK 44 (0)1245 493493 www.e2v.com

e2v CCD imaging sensors were launched recently on the Space Shuttle Atlantis as part of a mission to upgrade and repair the Hubble Space Telescope. The imaging sensors equip the Wide Field Camera 3 (WFC3), a new instrument installed on Hubble to take largescale, extremely clear and detailed pictures of the universe over a very wide range of colors. The mission equipped the telescope to explore the universe in greater detail by replacing equipment and installing new instruments.
