48 Cluster Report Optics and Photonics – Optical Analytics For more than 130 years, G. Lufft Mess- und Regeltechnik GmbH, headquartered in Fellbach, Germany, has been developing and producing professional components and systems for climate and environmental measurement technology. Following the takeover of the cloud altimeter product range from Jenoptik subsidiary ESW GmbH in April 2014, the newly established Optical Sensors business unit of G. Lufft has settled in Berlin-Adlershof. G. Lufft products and equipment are to be found wherever atmospheric pressure, temperature, relative humidity and other environmental factors require to be measured or recorded. These applications include industrial climate measurement technology, environmental technology, climatology, agricultural meteorology, and traffic engineering. The Berlin division is primarily involved in the sale and further development of cloud altimeters and the family of laserbased snow depth sensors. difficult measurement conditions. The excellent wavelength stability of DFB lasers eliminates the need for regular recalibration and can significantly reduce maintenance costs. Colibri Photonics GmbH is an innovator for high-quality, non-invasive micro- and nanoprobes for optical measurement of oxygen levels. The customer-specific high-performance oxygen sensors are designed for use in human and plant physiology, as well as in biology and environmental analysis. Colibri Photonics’ primary customer base is in the life sciences working with micro and nanovolumes, such as manufacturers of lab-on-a-chip systems for cell-based testing, neurologists, oncologists, plant physiologists, and developers of bioreactors for three-dimensional tissue engineering. Oxygen levels can be measured without contact using lasers in a process called absorption spectroscopy. A part of Munich-based TOPTICA Photonics AG, eagleyard Photonics GmbH in Berlin-Adlershof offers DFB lasers that meet the strongest oxygen absorption lines. Due to their significantly higher output power compared to other lasers such as VCSEL, they are also ideally suited for industrial use under Since 2013, Stöbich technology GmbH has been developing and marketing innovative products in the fields of battery safety and fibre-optic sensor technology. It bundles the expertise of various companies to develop innovative products, organises joint development projects, takes over project management responsibility, and the manufacture of the resulting products. Issues the company tackles include battery management, optical gas sensors, fibre-optic sensors, and intelligent materials made from tissue structures in cooperation with the Battery and Sensors Test Centre and HHI FS in Goslar. Possible reference materials are tested in the integrating sphere by being irradiated with a light source. © BAM Sensors for food quality and safety At the Leibniz Institute for Agricultural Engineering and Bioeconomy e. V. (ATB), optical methods are developed and used for the non-destructive recording of quality parameters in fresh food. Using such methods as flow cytometry, fluorescence, and UV spectroscopy, ATB is developing rapid tests for the identification of microorganisms. Optical methods under investigation at ATB include thermography, hyperspectral analysis, chlorophyll fluorescence image analysis, absorption spectroscopy in the VIS and NIR range, spectrophotometry (mobile), and Raman and terahertz spectroscopy (soil analysis).

Cluster Report Optics and Photonics – Optical Analytics 49 In addition to the research institutes, several companies in the region are also very involved in environmental analysis. Müncheberg-based Umwelt-Geräte-Technik GmbH offers an entire range of measuring instruments with which water, wind, and weather conditions or plant growth can be measured. Founder Manfred Seyfarth received a special Future Prize Brandenburg in 2017 for his commitment to ecology. Sensors for a wide range of applications are also offered by deka Sensor + Technologie Entwicklungs- und Vertriebsgesellschaft GmbH. These include light sensors in the infrared, optical and ultraviolet ranges to complete measurement systems that monitor physical parameters such as temperature, pressure, humidity, and wind speed that are used in everything from weather stations to industrial settings. Comde-Derenda GmbH also specialises in innovative sensor technology and environmental measuring technology. The company based in Stahnsdorf has particular expertise in the manufacture of devices for monitoring air quality, such as sensor solutions for measuring dust and gas concentrations. Umweltanalytische Produkte GmbH offers sensor technology for data acquisition in soil physics, meteorology, plant physiology, and hydrology. These devices allow investigations of the water and nutrient balance, biological test series, and the investigation and monitoring of contaminated sites. While some companies are considering relocating their activities to Asia, there is also movement in the opposite option: the Indian company Everest Instruments Pvt. Ltd. established Everest Scientific Europe, a development centre in Berlin-Adlershof at the beginning of 2016. The parent company in India specialises in monitoring the quality of milk and other foodstuffs. Oculyze GmbH in Wildau has developed an automated, digitalised, and mobile microscopy platform. The Oculyze microscope consists of a detachable optical module (~400x), a smartphone, and an Android application with integrated connection to the company server where the image recognition takes place. The optical module is plugged onto the smartphone and the enlarged image is displayed on the screen via app. The system was first used to analyse yeast levels in the brewing process. The mobility of the platform promises many other applications for the device. A portable Raman laser system for field use was developed at FBH, seen here in an orchard. © FBH/A. Müller
