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...
Hyphenated Raman - OCT Clinical Diagnosis of Skin Cancers
Hyphenated optical techniques combine different measurement modalities in the one instrument to provide a more comprehensive set of complimentary information for carrying out medical diagnosis. This note describes how Raman Spectroscopy (RS) and Optical Coherence Tomography (OCT) have been combined into one instrument to provide a portable machine...

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...

High Performance SWIR Imaging Cameras
Silicon based area detectors (e.g. CCDs or CMOS) are widely used in high performance imaging applications, detecting wavelengths from soft x-ray through to near infrared (NIR). Typically the quantum efficiency (QE) of these detectors decreases rapidly as the detection wavelength increases further into the NIR region.

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...
