Miniaturization Drives Spectroscopy Miniaturization Drives Spectroscopy
In the spectroscopy industry, "downsizing" in 2001 described more the miniaturization of instrumentation than the reduction of work forces. Indeed, since the release of the first commercial miniature spectrometer in the early 1990s -- the fortuitous...

Scientific Cameras Push Perfection Scientific Cameras Push Perfection
A scientific camera does much more than simply capture a picture of an object under study. If an acquired image is to reliably reflect measurements of chemical concentration, cell growth, etc., the digital values associated with each pixel must...

Technology Close-Up
Diode-pumped lasers are rapidly growing more powerful as their excitation sources increase in power and as coupling technology improves in efficiency. Pumping a single solid-state laser typically requires the combined emission of several diodes....

The Right CMOS Camera for the Job The Right CMOS Camera for the Job
While the CCD offers the best sensor performance for digital imaging, the CMOS image sensor is superior in terms of integrating functionality on-chip. Even the much-touted camera-on-a-chip is not beyond the capabilities of CMOS technology, promising...

Vision in a Box Vision in a Box
Most of the theoretical advances that form the basis of modern industrial machine vision are more than 20 years old. To confirm this assertion, one need only review the contents of Digital Picture Processing, edited by A. Rosenfeld and A. Kak...

Hidden in Plain Sight: Calcium Fluoride's Intrinsic Birefringence
For years, lithographers have applied progressively shorter exposure wavelengths to reduce the minimum feature size on integrated circuit chips. However, this approach recently encountered an unexpected and little-known phenomenon: the intrinsic...

Spectrophotometry Takes Measure of Deep-UV Lithography
High-performance deep-UV spectrophotometry played a vital role in the research and development of 193-nm lithography. Pushed further, it will do the same for 157-nm lithography by providing optical analysis of the projection lenses, illumination...
