The new Research Center MAIN of TU Chemnitz in Germany recently added a cleanroom to their Optics/Plasmonics laboratory. The lab required a large optical table surface installed in the cleanroom’s raised floor environment, a somewhat unusual setup. Click here to see how TMC solved this vibration problem.

The importance of vibration control in the machining and metrology of advanced aspheric optics
Aspheric optics are commonly used in advanced optical systems, such as AR/VR headsets, surveillance systems and semiconductor applications, to minimize size, weight, and cost. Achieving the required level of performance requires stringent control in the machining and metrology of the optics. One of the manufacturing tools used to make precision aspheres is a single point diamond turning lathe like those... -
Society of Electron Microscope Technology
7th December 2022 The Natural History Museum The SEMT was founded in 1970 as a forum for the exchange of ideas on techniques and applications in microscopy. It has expanded to become one of the foremost user groups in the country, addressing all aspects of microscopy from instrument design and specimen preparation to digital image acquisition.

EMC…What is it?
Wikipedia definition:Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. The goal of EMC is the correct operation of different equipment in a... -

Metal Coating of Styrofoam (XPS) and Polystyrene Foam (EPS) Samples for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY STYROFOAM? SEM imaging is an ideal tool to check the size and homogeneity of the cells in the polymer foam structure, and if the material has a closed or open cell structure. Other elements that can be studied are the foaming and cell formation efficiency, and how different agents influence these processes. Chemical... -
Metal Coating of Glass Fibres for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY GLASS FIBRES? SEM imaging is an ideal tool to check the homogeneity, compactness aof glass fibres in a polymer matrix. Other defects such as poor adhesion of the fibres to the polymer matrix (shown as clean fibres) can also easily be detected. Chemical microanalysis techniques (EDS) used in conjunction with scanning electron microscopy... -
Metal Coating of Nanofibres for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY NANOFIBRES? SEM imaging is an ideal tool to check the homogeneity and diameter of nanofibres. SEM manufacturers have developed specific software applications for a fully automatic fibre diameter distribution measurement. Nanofibres are also used in air filtration applications for antibacterial and nanoparticle applications. SEM imaging (eventually combined with EDS chemical microanalysis techniques) to... -
Metal Coating of a Face Mask for Enhanced SEM Imaging
WHY IS SEM IMAGING USED TO STUDY FACE MASKS? SEM imaging is an ideal tool to check the homogeneity, compactness and average diameter of fibres in the different face mask layers. The SEM image show a 10nm gold coated non-woven polypropylene filtration layer at 1400x magnification. Some SEM manufacturers have developed specific software applications for a fully automatic fibre diameter... -
Metal Coating of Biological Samples for Enhanced SEM Imaging: Collagen Membranes
WHY IS SEM IMAGING USED TO STUDY NANOFIBRES? SEM imaging is an ideal tool to check the fibre surface properties and the structure of collagen networks. In general, a lot of organic and biological samples such as tissue, blood vessels and cartilage provide very interesting information when imaged by SEM. Such materials however are very poor electrical and thermal conductors...
