Understanding the Differences in Focal Lengths
Understanding what focal lengths mean and how they work is very important when trying to find the perfect lens for the job. The focal length of an optical lens is basically the measurement of how strongly the lens can converge or focus and diverge or defocus light. The focal length is determined by how quickly the lens can take collimated rays and bring them into focus. Lenses with a shorter focal point have more optical power than those with longer focal lengths because they have the power... (read more)

Laser Beam Expander Theory (.pdf)
Perfect Gaussian Laser beams are often characterized by a parameter known as beam divergence. Divergence is the angular spreading of light waves as they propagate through space. Even a perfect unaberrated ray of light will experience some beam divergence due to diffraction effects. Diffraction

Specifying Resolution of System Components
). No lens (even theoretically perfect) at any resolution can fully transfer this contrast to the image because of the diffraction limit. In fact, as the line spacing is decreased (i.e. the frequency increases) on the target, it becomes increasingly difficult for the lens to efficiently transfer
New Technology Offers Better Choices in Spectrophotometers
Although color spectrophotometers are designed to measure specimens both accurately and repeatably, they accomplish these measurements only within tolerances. Spectrophotometers aren't perfect measuring devices, and how well they measure often depends upon factors under the control of the system
OMEGASCOPE(R) Handheld Infrared Thermometer Goes Wireless (.pdf)
Handheld infrared thermometers are very popular for making on the spot non-contact temperature measurements with little or no setup. These devices are completely self-contained and require no additional wiring or signal processing, unlike thermocouples and RTDs. They are perfect for determining
Understanding MTF Testing
is a way to incorporate resolution and contrast into a single specification. An easy way to interpret MTF results is to think of imaging a target with black and white lines (100% contrast). No lens (even theoretically perfect) at any resolution can fully transfer this contrast to the image because
