How Hexapod Motion Platforms Help Google Engineers Advance Cell Phone Cameras
By PI (Physik Instrumente) LP

An unsteady hand can ruin the most epic picture moment. The engineers at Google understand this and have taken steps to optimize the motion and image stabilization algorithms in their Pixel 2 camera. The Google Pixel 2 has been integrated with PI’s H-860 high-speed hexapod system that accurately simulates motion with 6 degrees of freedom and results in pinpoint accurate crisp images.

Practical Considerations For Near-IR LEDs
By Opto Diode

This application note provides practical considerations for current-driven LED devices.

Testing High-Volume LED Luminaire Builds

The lower operating costs of LED luminaires drive growing demand for them in consumer and commercial markets. This increased demand requires an adaptation to improved quality testing methods that can provide superior measurements and not slow down the process of production. 

Infrared (IR) Laser Components Catalog

Laser Components USA offers an array of infrared (IR) detectors and emitters used for many different applications including flame detection, gas monitoring, medical gas analysis, protein measurement, the inspection of surfaces, and other laser power monitoring applications. 

Lens Manufacturers: Do You Know The Best Test For Lens Performance?
By Kevin Urben, Image Science

A high-quality lens begins with a good design, tolerant to small manufacturing errors. The manufacturing process must be tightly controlled, from individual lens elements to final assembly. But, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is necessary.

Building A Do-It-Yourself Atomic Force Microscope
By James F. MacKay, Mad City Labs

Atomic force microscopes (AFMs) are versatile tools for characterizing surfaces down to the subnanometer scale. Researchers can build their own AFMs for as little as $30,000 using off-the-shelf components such as nanopositioning stages.

Neutral Density Filters Catalog

Hoya’s neutral density filters have nearly even spectral transmittance in the visible region and are classified by the average transmittance within wavelengths from 400 nm through 700 nm. These filters are able to control light intensity without selectively absorbing light with a specific wavelength.

Measuring Lens Assembly Thickness With The 157 Series Optical Thickness Gauge

This technical note provides details on how the 157 Series Optical Thickness Gauge by Bristol Instruments can be used to determine the precise thickness of cemented or air-spaced achromatic doublets and triplets (as well as more complex lens stacks), and other lens assemblies.
