The Biophotonics Revolution in Healthcare

More stringent environmental regulations, exhaustive control of the quality of food, and less‐invasive medical diagnostics devices are social challenges that must be addressed in the next years. To face them, the development of new detection tools allowing cost‐effective, fast and simple analysis is required.

Measurement Technology

The Next Level – Controlled Conformal Coating Processes

Talking about purified assembled printed circuit boards (PCBs), e.g. in automotive industry for control of airbag or anti‐lock braking systems (ABS), one of the main issues is the protection against environmental impact. The error‐free functionality must be guaranteed even at the North Cape, the Rainforest or in the desert and this warranty has to be provided for even a decade.

Photonic Integration: New Applications Are Visible

Chip integration has allowed for many years already to miniaturize optical systems into photonic circuits, improving in performance and robustness while decreasing cost and weight. Traditional applications have been telecom and datacom components, but as technology matures in these markets, new emerging applications arise on healthcare and biochemistry sensing. From optical coherence tomography (OCT) medical…

Spectroscopy

Moving Towards Ubiquitous Spectral Sensing

Material analysis tools have long been an important asset for research and production in a range of domains and markets, and have transformed our knowledge, development and quality control capabilities over time. Academic teams use material analysis for assessing composition and detection of chemicals in disciplines ranging from archaeology to medicine, food analysis, agricultural research, and biotech.

Commercial Tests and Assembly in Silicon Photonics

As the world’s appetite for data skyrockets, silicon photonics (SiP) promises fresh bounties of bandwidth, scalability and energy efficiency. The transformation of data transmission (and, soon, computational processes) from electronic to photonic is comparable to the development in integrated circuitry five decades ago: It is a fundamental shift that marks a watershed moment in the history of technology. However, there are…

Medical Technology

Next Generation Refractive Procedures Rely on Excimers

Dating back nearly three decades, laser refractive surgery for vision correction represents a suite of well‐established and increasingly popular elective medical procedures. For instance, in the US, where elective procedures are more common than in other countries, laser refractive surgery today is the single most popular elective “surgical” procedure. With a range of different procedures and variants now available, the key…

Fiber Optics

Polarization‐Maintaining Optical Components

In a polarization‐maintaining (PM) fiber system, the quality of a connection plays a crucial role. In order to offer the best overall performance, PM fibers must be properly oriented inside the connectors and the alignment features on these must guarantee an appropriate orientation across the mating adapter. Due to different mechanical contructions, not all fiber connectors and mating adapters are suitable for PM…

Atomic Layer Deposition for Coating of Complex 3D Optics

Atomic Layer Deposition (ALD) is a chemical vapor coating technique that has recently been adapted for precision laser optics to perform highly conformal multilayer coatings on complex 3D substrates like hemispheres, axicons or multi‐sided prisms. In our brief report, we explain some ALD fundamentals and describe the way from idea and single‐layer films to simple AR (anti‐reflection) coatings and even more ambitious…

Laser Cavity Stability Analysis by Multiphysics Ray Tracing

In laser engineering, one of the most important tasks for designing a stable and power‐scalable laser is to run a laser cavity stability analysis with the thermal lensing effect taken into account. Multiphysics simulation is required for such analyses and Comsol has developed new simulation models and apps using novel multiphysics ray tracing methods. In this article, we briefly review the conventional method and introduce…

Imaging

Telecentric Imaging with Line Scan Cameras

Line scan cameras are semiconductor cameras used in many industrial environments. Most have just one photosensitive linear array, but some have single arrays with sensitivity for different colors (for example: RGB line scan camera with three arrays). A line scan camera can be used for one‐dimensional measurements, such as determining the width of a gap, or for producing a two‐dimensional image by moving either the camera or…

Application Feature

The Contactless Component Counter

Optical Control’s CCX had begun as a world first and has been patented in parts, simplifying the work of electronics production. Meanwhile, the X‐ray scanner is becoming standard equipment in SMD production and thereby creates a prerequisite in the direction of Industry 4.0.

Application Report

Gear Inspection in Record Time

In cooperation with various universities, the French manufacturer Mesure‐Systems‐3D (MS3D) has developed a contactless in‐line test system especially for gears. With GearInspection (Fig. 1), a gear with 23 gear teeth for example can be fully measured in 3D in less than thirty seconds. With 3D inline testing, the manufacturer obtains real‐time information about the effects any changes to the production parameters will have….
