Application Notes Available from PixCellent Imaging Ltd.


Introduction to Applications of CCDs in Astronomy


COOLED CCD imaging systems are already widely used in astronomy as the scientific detectors of choice. Their role in telescope pointing, control and wavefront correction is much less well known. This information is intended as a general guide to the ways that CCD systems may be used for acquisition, guiding and wavefront sensing applications in astronomy.

PixCellent CCD Imaging Systems for Optical Microscopy:


OPTICAL MICROSCOPES are widely used in the life sciences as well as the physical sciences. This note is principally directed at life science work and is a general guide to applications for life scientists wishing to improve the quality of the imaging work they undertake with optical microscopes.
Optical microscopy may use transmitted light, including brightfield, phase contrast and darkfield microscopy (where the light detected is passed from a light source through the specimen onto the detector); it may use fluorescent emission (where a short wavelength light source is used to illuminate the specimen and the fluorescent emission from the specimen is detected); or it may use luminescence (where the specimen is self-luminous).

In addition to conventional microscopes, the confocal microscope is increasingly used. These have the advantage of being able to suppress light (transmitted in some cases but mostly fluorescent) that is seen as a diffuse background from out-of-focus parts of the specimen in order to give sharper images. Confocal microscopes can give beautiful images but they do require rather high light levels, levels that may be reduced substantially with the use of PixCellent CCD imaging systems.

In many cases the needs of the optical microscopist will be well met from the Standard range of CCD cameras sold by PixCellent , but some specialist applications will need systems selected from the Specialist Products Listings.

Hot Electron Imaging with PixCellent CCD Systems:


INTEGRATED CIRCUIT (IC) design complexity continues to develop at a very great speed. As design rules permit smaller and smaller component dimensions to be achieved, it is increasingly difficult to check that both the design and the production process will meet the stringent quality requirements of IC consumers.

When an integrated circuit has a faulty junction, hot charge carriers (electrons or holes) may generate weak visible or near infrared (NIR) light. By looking carefully at an operating IC with a sensitive scientific imaging system, problem areas within the IC may be located with precision.
