Practical Uses And Applications Of Electro-Optic Modulators
 
By Newport Corporation

The purpose of electro-optic amplitude and phase modulators is to allow for the electrical control of the amplitude, phase, and polarization state of an optical beam. These external types of modulators do not cause any degrading effects on the laser linewidth and stability, unlike direct modulation techniques. This white paper discusses the electro-optic effect and describes the practical uses and applications of bulk electro-optic modulators.

Fast Optical Alignment For SiP Production

Testing and packaging of silicon photonics elements requires nanoscale alignments that cannot be performed using visual or mechanical references. This article presents PI’s solution  for fast, parallel, nanoscale-accurate, multi-DOF global optical alignment optimization.

Near-Field Scanning Optical Microscope

The MCL-NSOM is a fully operational near-field scanning optical microscope manufactured on Mad City Labs’ versatile RM21 inverted optical microscope. This instrument is designed to allow users to convert between NSOM, SPM, and fluorescence optical microscopy techniques.

Semi-Transparent Mirrors For Visually Dynamic Hospitality Displays

Hotel, restaurant, and retail owners are increasingly using aesthetically pleasing high-performance semi-transparent mirrors to create a visually dynamic display/mirror combination. These mirrors are constructed with a display unit hidden behind the glass that is not visible until powered on. 

Faster, Smaller Delay Lines Drive OCT Applications Further

Optical coherence tomography (OCT) can be used in many medical applications including displaying real-time details of eye diseases, detecting skin cancer, or monitoring heart surgery. The OCT market is set to grow even further over the next few years as the efficiency and effectiveness of imaging improves.

Ultraviolet Transmitting, Visible Absorbing Filters

Hoya offers dark glass (nearly black) filters that are capable of transmitting the ultraviolet region and absorbing the visible region. These filters are ideal for single extraction of ultraviolet rays, and are often utilized for selectively transmitting the 253.7 nm and 365 nm wavelengths.

Clear The Air: New Optical Filters For Sensors And Detectors

Environmental air quality; proximity control; crowd counting; climate change; the “Internet of Things”.  Our world has become an increasingly monitored place where the proliferation of sensors and detectors allows us, and our devices, to better understand and interact with our environments.  

Propulsion And Energy Research Laboratory Uses High-Speed Digital Cameras In Turbulent Combustion Studies

This case study discusses the use of the FASTCAM SA-Z to effectively slow down the turbulent flow of motion through the acquisition of a large number of images played back at various slow speeds for frame by frame data analysis.

Direct Imaging Of Shale Gas Leaks Using Passive Thermal Infrared Hyperspectral Imaging

Many types of natural gas from shale formations are odorless, colorless, and highly flammable, and leaks/emanations are important considerations for safety and the environment. This application note illustrates the benefits of using an imager at a site where shale gas leaks unexpectedly happened.

Three Things To Consider Before Purchasing A High Speed Camera
 

At Photonics West 2017, Gene Nepomuceno with Vision Research spent a few minutes with us discussing the three main factors one should take into account before selecting a high speed camera – resolution, frame rate, and sensitivity (with an honorable mention for transferring the data off of the camera).
