Clearly Superior Epoxies for Optical Applications
As technology in the optics industry continues to advance and improve, careful consideration of the properties of epoxies must be evaluated. When determining the most effective adhesive to be used in opto-electronics, medical and other optic related industry applications, trade-offs of key characteristics should be assessed. Here is a guide to the...

The Measurement of High Optical Densities (up to 8 Abs) in the Near-Infrared
The optical densities of various materials used in the manufacture of laser safety eyewear have been determined in the NIR. The lens materials were measured over wavelength ranges corresponding to the laser wavelengths for which the eyewear was designed (InGaAs, 980 nm and Nd:YAG, 1064 nm). Prior to measurement, a variety of filters of known...
An Introduction to Pulsed-Current Laser Diode Drivers
The paper helps the reader to understand pulsed-current laser diode drivers and choose the right one for his or her application by explaining the basics of how they work and the components that comprise them. Ideal and real current sources are defined and explained, leading to an explanation of compliance voltage.

The Benefits of Modern CMOS Sensors in Industrial Line Scan Cameras
As sensor technology has improved in leaps and bounds, the old rule of thumb familiar to many line scan camera users has lost much of its punch. The idea that CCD = high image quality while CMOS = speed is only true anymore under very limited circumstances, since the preconception inaccurately reflects the current performance levels offered by...
Characterization to the Extremes: Terahertz materials characterization at cryogenic temperatures and high magnetic fields
In continuing pursuit of improved performance, higher processing speed, and more compact packaging, researchers spend considerable time identifying and characterizing novel and previously unexplored materials. Recently, the terahertz frequency range has emerged as a new frontier for materials science, helping to map out this unknown territory....

Beam Expansion - Standard Concepts Re-interpreted
Everyday work in an optics laboratory would be unthinkable without beam expansion systems. They serve to optimally adjust the beam cross sections between the light sources (e.g. lasers) and the subsequent optical elements. Precise illumination of the optically effective surfaces is essential, especially for beam shaping and focusing with high...
Dynamic – Dynamic Range
The dynamic or dynamic range of a CCD-camera system is a widely used term to characterize the ability of a camera system to measure or image light/dark differences. In the field of photography, the dynamic range is analogous to the contrast range. However, each manufacturer defines dynamic range differently. A distinction must be made, between...

Measuring Optical Densities Over 10 Abs on the Agilent Cary 7000 Universal Measurement Spectrophotometer (UMS)
High blocking optical filters deliver critical optical control in a wide variety of consumer and industrial products. Highly attenuating (i.e., high optical density) filters are used in personal protective equipment, such as laser safety eyewear, through to precise, low light level control in optical systems for enhanced sensitivity at preferred...
