Motion control specialist for over 50 years: Aerotech’s CEO Mark Botos and president Bob Novotnak in interview

The company’s history dates back to 1970, when Stephen J. Botos and two fellow engineers started prototyping a positioning system for industrial use in a garage. The first positioning system manufactured was a simple two-axis electromechanical application. A lot has happened in the past fifty years: the former 3-man start-up has grown into a high-tech company with over 500 employees. We spoke with CEO Mark Botos and Aerotech president Bob Novotnak about the company's development into a key player in the market for high-precision positioning systems and where the journey is still heading.

Laser Sources

Holographic recordings without compromise: Tunable lasers help streamline the fabrication of holographic optical elements

Stefan Trotzky (Meta Materials) & Niklas Waasem (Hübner Photonics)

Widely tunable continuous-wave optical parametric oscillator (OPO) systems help meet the demands on holographic optical elements (HOEs) for many use cases, including head-up displays and augmented reality devices. The wide tuning range allows for direct adjustment of the replay wavelength with little to no need for modification of the holographic recording geometry. HOEs fabricated using these OPO systems in conjunction with advanced photopolymer materials offer precisely controlled replay properties and exceptional diffraction efficiency.


Every breath you take: Laser absorption spectroscopy allows unprecedented focus on the air we breathe

Mark Naples (Umicore)

ESG. Three small letters perhaps, but they are having a huge impact on science, industry, and everyday life. In industries that operate in hazardous environments, such as oil and gas mining and refineries, those letters stand for much more than environmental, social, and governance policies. They represent a framework around which an entirely new operational structure must be built, changing every level of a business from the top down.

Laser Marking

Precision marking of glass with excimer lasers: Laser-generated microstructures and material modifications serve as colored marks

Jörg Meinertz, Lukas Janos Richter, Clemens M. Beckmann, and Jürgen Ihlemann (all: IFNANO)

Current laser marking of glass by CO2 lasers is mainly based on the generation of cracks or melt pits. Improved quality in the form of damage free, high contrast, and high resolution marking is possible by using deep ultraviolet emitting excimer lasers. Various methods of ablative microstructure formation or nanoparticle implantation are available to achieve colored marks on glass formed by opalescence, chemical modification, or plasmonic absorption.

Automating serial laser processing with cobots: High-precision surface finishing in tool and mold making

No more limitations due to the character set or material properties: laser markers can label a wide variety of workpieces of different materials, quickly and durably.

Trends in Manufacturing

Is laser technology profitable even for small quantities?
Compact stand-alone systems for metal cutting and marking

Relying on laser technology for metal cutting or marking has many advantages in practice. The processes work without contact. This protects the processed material and the tool, because a light beam does not wear out. Also, no other processing method is as flexible in terms of shaping. Tools do not have to be changed and the workpieces do not have to be clamped in time-consuming preparation. Until now however, the high purchase prices were an obstacle to using laser technology – especially for cutting – even for smaller quantities or prototype production. But in the meantime, there are also affordable systems suitable for such applications.

Technology Report

The future of optical measurement technology: A review of new developments in optical metrology and industry trends in the digitalization and integration of these solutions for in situ and inline measurements

Antonio Castelo-Porta

Optical metrology is one of the key technologies in today's manufacturing industry. It can be generally defined as the science of measuring with light, and it is widely used to evaluate the physical properties of products (or some of their parts or components) and to monitor large infrastructures and facilities. In this article we will review some of the current technologies for optical measurement in different manufacturing industries, the new developments and the trends related to the continuous demand for high- precision and high-efficiency solutions.
