Optics, Sensors & Detectors White Papers
Optimax OTR Coatings
Optimax has developed a novel optical coating (OTR) that protects optical surfaces in even the most extreme environmental use conditions. OTR coatings have been demonstrated to provide excellent resistance to latent scratching, staining and dimming of chemically sensitive optical glass surfaces in hot, humid environments.
10 Steps to Choosing the Right Optical Coating
There are some critical steps you should consider when selecting an optical thin-film coating to maximize your optical systems’ performance. Small changes in requirements can often have a significant impact when evaluating performance and cost....
Optical Power Meter
An optical power meter measures the photon energy in the form of current or voltage from an optical detector. Newport’s 1936/2936-R Series Optical Power Meters are among the most versatile power meters in the market, and the electronics adapt to a...
Integrating Sphere Fundamentals and Applications
An integrating sphere collects electromagnetic radiation from a source completely external to the optical device, usually for the purpose of flux measurement or optical attenuation. Newport’s general purpose spheres (GPS) are designed as...
Precision Infrared Narrow Bandpass and Dual Bandpass Filters Featuring Low OH-Band Absorption
Alluxa’s new class of Infrared (IR) bandpass and dual band filters bring the precision of dielectric filters to the IR between 2 and 5 microns. They are manufactured with an advanced, plasma enhanced PVD process using durable, hard metal-oxide, and...
LED/OLED Design Using Mixed-Level Simulation
There has been extensive research to improve the design of light-emitting diodes (LEDs) and organic LEDs (OLEDs) to enhance light extraction efficiency, improve beam shaping, and allow color tuning. Due to the range and scales of geometric...
Easy High Dynamic Range Imaging for Welding Vision
Welding has long been a key technology for assembling metals parts in various industries. Nowadays with the constant search of quality and productivity, welding has become increasingly sophisticated with the introduction of new processes and the...
Infrared Camera Accuracy and Uncertainty in Plain Language
How accurate are thermal imaging cameras, and how are they calibrated? Understanding infrared camera accuracy and sensitivity can help clarify the value of well-calibrated thermal imaging cameras. In this paper, we use layman’s terms to explain how...
CMOS Image Sensors are Entering a New Age
In the early 90’s, it was suggested that Charge Coupled Devices (CCDs) were in the process of becoming extinct and considered to be ‘technological dinosaurs'. The prediction is not entirely wrong, if the announcement made by Sony in 2015 is taken as...

High Precision Lens Assembly with Alignment Turning Machines
In recent years, alignment turning technology has experienced some key developments. Progress has been made with regard to aspheres, cylindrical surfaces or "best fit" centration of lens groups. It has also been possible to significantly increase...
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...
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.
DRS Technologies’ Patented Sensor Technology Revealed
Learn the truth about what’s behind DRS Technologies’ competitive advantage over thermal sensor manufacturers – the patented Advanced-Absorber Microbolometer Superstructure, providing better performance through superior image quality and enhanced...
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...
Ultra-Narrowband Optical Bandpass Filters with Large Format and Improved Temperature Stability
Hard coated ultra-narrowband optical filters made using modern plasma processes offer much improved transmission, temperature stability and out of band blocking as compared to legacy soft coatings. These filters are used in optical systems as...
High Volume Optical Component Testing Using an Agilent Cary 7000 Universal Measurement Spectrophotometer (UMS) with Solids Autosampler
In this study, we demonstrate increased productivity and reduced cost-per-analysis with automated, unattended multi-angle R/T analysis for multiple samples of uncoated fused silica using an Agilent Cary 7000 UMS fitted with an Agilent Solids...
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...
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...
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,...
Understanding Infinity-Corrected Objective Resolving Power and Magnification
This informative white paper from Edmund Optics covers a range of topics from the field of Microscopy, including terminology, application examples, and descriptions of different types filters such as dichroic, emission, and excitation filters used...
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...
Flat Top, Ultra-Narrow Band Pass Optical Filters Using Plasma Deposited Hard Oxide Coatings
Flat top and square narrowband filters of less than 1nm in bandwidth and transmission of >90% even 95% are now available at sizes of up to 250mm in diameter. Out of band blocking levels of 3 OD to 6OD can easily be added. These filters can be used...
