Optimization of LED Lens Components using TracePro®
TracePro® is an award-winning opto-mechanical design software for layout, optimization, and analysis of illumination systems. This white paper illustrates how TracePro’s 2D and 3D optimization utilities are designed to help CAD designers without optical engineering expertise design a variety of LED optical components – including practical...
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 the...
Design of Long Working Distance Graded-index Fiber Lens With a Low NA for Fiber-Optic Probe in OCT Application
A fiber-optic probe for optical coherence tomography (OCT) applications typically includes a short section of graded index (GRIN) fiber fused onto a single-mode (SM) fiber. The GRIN fiber acts as a lens to focus the output of the SM fiber and to collect the reflected light from the sample. In this paper we will use the beam propagation method...

Tailored Bar Concepts for 10 mm-mrad Fiber Coupled Modules Scalable to kW-class Direct Diode Lasers
Laser modules based on newly developed tailored bars are presented. The modules allow efficient fiber coupling of more than 320 W into 10 mm-mrad or 160 W into 6 mm-mrad at one single wavelength. For further power scaling dense wavelength coupling concepts are presented which enable kW-class lasers with a beam quality of 10 mm-mrad.
Measurement of Film Stacks in Cell Phones and Tablets Using White Light Interferometry
With the explosive growth of the tablet and smart phone market, equipment suppliers are developing more complex structures that include polarizers, LCDs, structured air gaps, and more. There are few systems that provide the measurement capabilities to examine all the layers, non-destructively. Lumetrics will provide examples of how its white light...

Improving Inspection Results Using High Dynamic Range Imaging (HDRI)
Designers and operators of automated inspection systems have long been challenged with completing accurate inspections when those inspections required high dynamic range, or when there was a need to capture critical details in objects or environments with high contrast between their brightest and darkest areas. High dynamic range was especially...
Hyperspectral Imaging Ground Surveying
An ultra-compact, easily deployable, high-performance hyperspectral imager is deployed specifically for use on small unmanned aerial vehicles (UAVs), to monitor the details of spatial, temporal, and spectral representation of ground objects.

e2v is a leading global provider of high performance image sensors for space applications with over 100 devices flown in missions ranging from Earth observation to planetary exploration and space science.
Modifying Laser Beams: No Way Around It, So Here’s How
To apply a laser to an industrial process, medical therapy, or communications technology, it is usually necessary to modify the laser beam to achieve the desired results. Beam measurement tools make this possible. We will discuss how to match an appropriate laser beam profiling technique to a laser application, including building an aligned...

Fabricating and Testing Freeform Optics: Current Capabilities, Lessons Learned and Future Opportunities
Freeform optical shapes or optical surfaces that are designed with non-symmetric features are gaining popularity with lens designers and optical system integrators. A common question about freeform optics is, “If I design it, can you really make it?” This paper will overview a freeform optical fabrication process that includes generation, high...
Methods for Measuring Flat Panel Display Defects and Mura as Correlated to Human Visual Perception
Human vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production environments. However, traditional methods for automated defect detection do not relate directly to human perception. Accurately correlating human...

Narrow-Line Fiber-Coupled Modules for DPAL Pumping
A new series of fiber coupled diode laser modules optimized for DPAL pumping is presented, featuring greater than 400W from a 600µm core fiber of 0.22NA. Addressing one of the key challenges in DPAL pumping, the modules achieve a spectral width of <<0.1 nm and wavelength tunability of +/- 0.15 nm. A limiting factor in the reduction of the spectral...
UVSCALE Visualizes UV light amount distribution by color density
One side of the base film has a UV light sensitive layer, with the opposite side having a white-colored layer. The light sensitive layer changes color according to the amount of UV light it receives, so the amount of light distributed on the exposed surface is easily seen by observing a light sensitive layer and white-colored layer are attached to...
Vision Research High-Speed Digital Cameras Instrumental in Teaching Construction Site Safety
There is a good reason construction workers are asked to wear hard hats, gloves, safety goggles, and various other safetyequipment while on the job; construction sites are dangerous. Filled with heavy and sharp objects, platforms of varying heights, flying sparks and debris, and a number of other potentially dangerous elements, it’s no wonder so...
