Multispectral Array Technology - Meeting New Space Economics and ObligationsFor over 40+ years, Materion Precision Optics (formerly Barr Associates) has been providing cutting edge multispectral arrays for high end government sponsored programs (Landsat, VIIRs, etc.). By working closely and collaborating with our customers over the years, we have developed solutions to improve large angle scatter (LAS), ghosting, R%, stray light management, and channel-to-channel cross talk. We have also implemented mechanical solutions for stress balancing, opaque masking, dimensional...
Using Lighting To Optimize Camera PerformanceA rule of thumb in imaging is that there can never be too much light. A common problem is finding enough light to clearly image a subject. Utilizing light sources in an efficient and deliberate manner can address this problem by reducing the amount...
When to Choose HOT MWIR Over Uncooled LWIRCooled midwave infrared (MWIR) cameras have long held a tactical advantage over uncooled longwave infrared (LWIR) cameras in many airborne and ground-based missions. But while cooled MWIR cameras are highly sensitive, they are also larger, heavier,...
Ordering Options: What Does Your Camera Need?This paper covers how to best optimize a camera order to improve camera performance. The topics in this paper include: camera ordering options, removing cover glass, removing all the glass within the camera (including the optical window and cover...
Using a Single Versus Multiple Cameras In Aerial ImagingThis paper covers the use cases of using multiple cameras for aerial imaging and address the advantages of such set ups over single camera systems. Topics include: Creating mosaics to image wider areas, software stitching and why pixel width and...
The Fast Lane to Embedded VisionSensor Modules are small imaging solutions used to easily integrate customized vision technologies into machines and devices that allow them to see. Developers of robots, drones, IoT, consumer devices and surveillance applications benefit from...

Radiation Resistant LensesDrawing upon approaching 30 years experience — Resolve Optics has built a strong reputation for specialist lens design and manufacture of smaller production quantities of radiation resistant lenses and optical products on time to strict...
Replacing Hard to Source and Obsolete Optical ComponentsPeriodically organisations are faced with replacing hard to source or obsolete optical components within their camera, sensor, or instrument systems. It is at this critical point that you have to choose whether to search for an off-the-shelf...
Application in Optical Design: Optimization for Receiver Enclosed Energy in LiDAR SystemsEnclosed energy optimization can be an important way to achieve high-performance optical systems that have stringent irradiance requirements, such as spectrometers and solar concentrators. This white paper shows an example LiDAR receiver system with...
Comparing CCD vs. CMOS Sensor Performance for Pixel-Level Display MeasurementImaging systems rely on sensors to accurately interpret light as photometric data and enable evaluation of displays. This paper discusses properties of today’s high-resolution sensors used for image-based photometric display testing, and examines...
Displacement Feedback for Closed Loop Nanopositioning SystemsPiezo-based nanopositioners for moving objects in nanometer range require ultra-precise displacement sensors to increase motion stability and accuracy. A nine axis positioner setup was implemented in a high vacuum environment and our laser...
How Laser Quantum Measures and Reports Root Mean Square (RMS) % Noise ValueOne of Laser Quantum’s goals has always been to create lasers with the lowest possible noise. Intracavity frequency-doubled lasers have an inherent noise of about 3% RMS. Several techniques have been developed over the years to reduce this noise,...
Understanding Total Measurement Uncertainty in Power Meters and DetectorsIt is important that users of calibrated power meters and detectors understand the total uncertainty or error that exists in their measurements. Often, users assume that the rated calibration uncertainty of the Newport detector or power meter is the...
Optimizing Imaging: Resolution & Dynamic RangeResolution and dynamic range are two important specifications when evaluating the capabilities of an imaging colorimeter, yet they are easily misconstrued. The assumption is that the higher the camera resolution, the higher the dynamic range, the...
The Future of Optics: How Optical Product Design will Change the WorldNew technologies are creating new opportunities in the optomechanical engineering space. Prepare for what lies ahead in optical product design by reading what 13 experts have to say about how optical product design has changed and where it’s going....
The Role of Lidar in our CitiesOur first city belonged to the Mayans, one of six areas in the world where ancient civilization arose independently. Once a thriving hub of culture, commerce and magnificent architecture in modern-day Guatemala, the city was recently discovered...
8 Things Engineers Should Know About Thermal ImagingAdding thermal imaging sensors to your next project can give your customers the ability to see the unseen, and expand their senses into the unknown. If you’re considering adding thermal sensors to your next design, there are a few things you should...
The Most Important Camera Parameters for Aerial ImagingSelecting components for an aerial imaging payload does not have to be complicated. Although the right camera choice is crucial for an aerial imaging system, the key to a success is to focus on the specifications that matter the most when imaging...
Optical Materials in CST STUDIO SUITEThis paper demonstrates the electromagnetic simulation of optical materials and explains how anisotropic and nonlinear material properties can be modeled virtually. Topics covered include birefringence, dichroism, magneto-optical activity and Kerr...
Accelerating Photonic Simulations with the Effective Index Method in RSoft ToolsThe Effective Index Method (EIM) can be used in Synopsys RSoft™ photonic design software to greatly reduce the computation time and memory requirements of a simulation by converting a 3D structure into an approximate 2D structure. This is also...
SWIR Camera Test – The New Swux UnitSWIR imaging technology based on InGaAs sensor products has been a staple of scientific sensing for decades. Large earth observing satellites have used InGaAs imaging sensors for applications that have proven benefits in several markets. These very...
How to Design a Detector Noise Limited Instrument with PbSe DetectorsPyrometers, NDIR gas analyzers, and flame monitoring systems, often make use of MWIR photoconductive PbSe detectors. Particularly, when high sensitivity and quick response time at an affordable cost are required. In order to achieve the optimal...
Key Considerations when Designing and Implementing an Outdoor-Ready Smart Imaging SystemThe key to a successful all-in-one imaging system is the use of embedded systems – especially when it comes to designing a custom proprietary system. This white paper walks you through key elements to consider when designing an embedded vision...
Working in the Basement: Measuring Signals Below the Noise Floor with a Lock-In AmplifierMeasuring optical signals in the femtowatt (10-15) to nanowatt (10-9) range can be a daunting task. Signal levels this low are lost in typical detector noise levels and swamped by background light. The noise floor for photodiode detectors operated...
