CCD Cameras - (516 companies)Charge coupled device (CCD) cameras contain light-sensitive silicon chips that detect electrons excited by incoming light. They also contain micro circuitry that transfers a detected signal along a row of discrete picture elements or pixels, scanning the image very rapidly. CCD cameras use two-dimensional CCD arrays with many thousands of pixels. Search by Specification | Learn More

Rotek, Inc.
Slewing Bearings for Antennae and TelescopesROTEK manufactures slewing bearings for Antennae and telescopes. Rotek's slewing bearings are machine elements which absorb all axial and radial forces and the resulting tilting moments in a single self-retaining and ready-to-install unit.Their low profile and an excellent weight/performance ratio, open center, and the possibility of an integrated gearing make Rotek slewing bearings ideal structural components. Rotek manufactures slewing bearings from 12 inches to 50 feet as non-segmented... (read more)Browse Slewing Rings and Turntable Bearings Datasheets for Rotek, Inc. -

Rulon J Helps Astronomers Reach for the SkyComposite filter lens carrier pads replace aluminum 14,000 feet above sea level. Our latest installation brings TriStar's commitment to customer service and product innovation to a whole new level; we are literally reaching for the sky. We've installed Rulon J on one of the world's largest telescopes; a 3.6 meter optical/infrared telescope in an observatory 14,000 feet above sea level. Located on a dormant Hawaiian volcano, this application has unique altitude, pressure, wear and temperature... (read more)Browse Plastic Bearings Datasheets for TriStar Plastics Corp. -
Brookfield Engineering Laboratories, Inc.
The Falling Ball Viscometer...The Falling Ball Viscometer utilizes the simple but precise Hoppler principle to measure viscosity. The basic concept is to measure the elapsed time required for the ball to fall under gravity through a sample-filled tube inclined at an angle. The tube is mounted on a pivot bearing which quickly allows rotation of the tube 180 degrees, thereby allowing a repeat test to run immediately. Three measurements are taken and the average time is converted into a final viscosity value in centipoise. The...

Hubble Confirms Existence of Massive Black Hole at Heart of Active Galaxy
that is extremely massive but extraordinarily compact a black hole. "Once you get that measurement, all you need is straightforward Newtonian physics to calculate the mass of the central object that's making the disk spin," says Harms. The measurement was made by studying how the light from the disk...
