Startup To Acquisition: Industry Experts Weigh In
By Ed Biller, editor, Photonics Online

Should your startup sign on with an incubator, an accelerator, or neither? Where will your funding come from, and how long will it take? And, perhaps most important, do you have the talent in-house to take the company where you want it to go, or should you seek out an acquirer? Hear what experts had to say on these topics and more. 

Spotlight On Polarization
Understanding Laser Induced Threshold (LIDT) For Laser Optics

The process for finding the laser induced damage threshold (LIDT) for laser optics has become increasingly more complex with different considerations for determining measuring and testing laser optics, including the laser’s wavelength, beam size, polarization, and angle of incidence.

Product Video: High-Speed 2D Polarization

Andrew Bridges discusses CRYSTA, which takes a conventional high-speed camera and adds an affixed micropolarizer array to a CMOS sensor, giving it the ability to detect phase difference and allowing the operator to plot birefringence or retardation in transparent or semi-transparent materials. 

0 To 60 Degree, Polarization Optimized Antireflection (AR) Coatings

Abrisa Technologies provides very wide-angle antireflection (AR) coatings for p-plane and s-plane polarization. These coatings support high throughput efficiency for broad-angle, polarization sensitive applications such as switchable Bragg gratings and SLMs used in laser beam steering.

How To Assess Thermal Camera Range For Site Design

When laying out a site design for surveillance using currently marketed uncooled thermal cameras, it is important to understand the coverage capability of the cameras under evaluation in terms of field of view and range. 

Lens Manufacturers: Do You Know The Best Test For Lens Performance?

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.

NIR InGaAs Pixel Chip Fabrication

InGaAs pixel chips are utilized in products like 2D NIR/SWIR cameras, NIR/SWIR linear arrays, and avalanche photodiodes. This app note presents the process of creating NIR pixel chips, starting at the crystal growth of semiconducting InGaAs on an InP substrate wafer to the product inspection.

Infrared Camera Technology Supports New Applications With Asynchronous Laser Pulse Detection (ALPD)

Growing infrared applications are driving the need for unique IR imaging systems that range from SWIR to thermographic, uncooled imaging and LWIR systems. This paper discusses the features of Sierra-Olympic's new QI-SCD15-M1 and the advantages of its ALDP imaging mode.

Glass Polarizer For The Near Infrared: CUPO

Hoya offers CUPO, a thin glass polarizer for the near-infrared wavelength region that is designed to use light absorption of copper particles by an electron plasma resonance. With special features such as high isolation, low loss, and high reliability, the CUPO is ideal for compact-size optical isolators.

Product Video: Thin Film Coating Capabilities

This year at Photonics West, Dan Bukaty Jr. with PG&O discussed his company’s thin film coating capabilities. Watch the video to learn about their ability to coat large optics (up to 600 mm in diameter), as well as a new system that allows them to monitor optical coatings in real time, which ensures individual layer index accuracy and the ability to measure layer thickness down to 1 nm.
