The analyzer can be used for a variety of evaluation and inspection applications with many types of surfaces such as film, paper, and automotive, printed, or painted surfaces.
The RV1100 is a 3D machine vision system designed to measure and recognize randomly assembled production line parts with complex shapes and very few distinguishing features for robotic arm systems. It offers the benefits of one-time measurements of 3D pose, high-speed recognition, improved productivity, and reduced production costs. The RV1100 is ideal for use in industrial production applications such as automobile parts manufacturing, car manufacturing, and electronics manufacturing.
Piezo nanopositioning stages offer high-resolution and scanning speed, making them useful for super-resolution microscopy and optical trapping. The P-563 PIMars XYZ-Stages are designed with a parallel-kinematics arrangement with higher precision and responsiveness compared to nested or stacked multi-axis positioners.
Telops offers a variety of high-performance scientific instruments to meet the most demanding research applications. The MS-IR Series of time-resolved, multispectral imagers are able to combine measurements obtained with various attenuation filters to achieve a composite HDR image that shows hot and cold objects at the same time.
Flexible endoscopes are used in medical procedures where the scope cannot bend. This animation from SCHOTT demonstrates the transmission of light and data through external and internal rigid fiber optic light cables in endoscopy.
One of the key parameters for understanding how a laser will perform in an application is the spatial intensity distribution. In many industial laser cutting or welding applications, monitoring the beam quality is critical for successful operation. The measurement of the beam can either be made during the design stage of the laser, or it might be more sufficient for continuous real-time monitoring during the laser’s operation. This white paper addresses the general need for laser beam profile analysis, describes laser beam analysis instruments, and provides an overview of laser applications, in particular for infrared wavelengths.

CMOS Image sensors with a global shutter(GS) are ideal for a variety of applications including factory automation, unmanned aerial vehicles, and automobile advanced driver-assistance systems (ADAS). For these applications, CMOS imaging sensors with a global shutter are used to avoid image degradation caused by rolling shutter (RS) distortion.
Turbulent flows laced with particles can be found everywhere, including fuel droplets in combustion engines, to airborne pollen, to water droplets in clouds. Even though they have been studied often, questions still remain that have to do with the particles’ inertia prohibiting them from following turbulence flow, making the Navier-Stokes equations insufficient for solving their equations. This white paper presents a project studying the dynamics of inertial droplets in a turbulent flow in a well-controlled environment. Measurements of droplet size distribution and turbulent dispersion rate in this study are done with interferometric particle imaging (IPI) and phosphorescent tagging techniques.
The introduction of 3-D machine vision systems to automation processing overcomes the technological hurdles of machines being able to “see,” analyze, and make decisions in an unpredictable environment. Designed specifically for factory work, these new machines meet production requirements of high accuracy, speed, and low maintenance while also being durable enough to withstand factory conditions.
When designing micromaterial processing equipment, manufacturers need to consider a complex interplay of numerous factors, such as extremely accurate positioning of lasers for cutting, drilling, scribing, or for marking at the highest rate possible. For many integrated circuits, the required beam accuracies can be staggering. For example, processing equipment must be able to drill microvias and scribe trenches less than 10 μm in size. Display manufacturers must also accurately place and repair pixel circuitry at ever shrinking resolutions on increasing larger substrates. This requires advance tooling to avoid significant increases in processing time and costs.
Princeton Infrared Technologies, Inc. (PIRT), announces the world’s first and only MegaPixel (MP) shortwave-infrared (SWIR) camera with no ITAR export restrictions. The newest camera in Princeton Infrared’s family of SWIR imaging products to fall under the no ITAR restrictions umbrella is the 1280SciCam, with a 1280 x 1024 image sensor on a 12 µm pitch, featuring long exposure times, extremely low read noise, 14-bit digital output, and full frame rates up to 95 Hz.
