Product Information

The group's formation - joining other local action groups like ARCH and Garston Futures - has been specifically inspired by a number of recent plans for the area focussed around heavy industry and the processing of chemicals and waste. In addition to being a very effective standalone tool for thermomicrometric sample analysis, Linkam stages are often used to add temperature and environmental control to a range of complimentary techniques, from fluorescence microscopy to Raman spectroscopy, and from X-ray diffraction to ellipsometry. Each of these techniques requires careful experimental planning to ensure that the sample can be analysed correctly with the two devices working in unison, and at Linkam we regularly work with other instrument manufacturers to provide the market-leading temperature control solution across all of these techniques. Here, we take a deeper look at one technique in particular – ellipsometry – and how our collaboration with ellipsometry experts J.A. Woollam enables precision temperature and environmental control with a range of Woollam ellipsometers. Ellipsometry is primarily interested in how p- and s- components change upon reflection or transmission in relation to each other. In this manner, the reference beam is part of the experiment. A known polarisation is reflected or transmitted from the sample and the output polarisation is measured. The change in polarisation is the ellipsometry measurement, commonly written as: Collect over 1000 wavelengths from the ultraviolet to the near infrared – all simultaneously. Fast Measurement Speed CompleteEASE enables easy visualization of ellipsometry data acquired as a function of time and allows users to easily select individual time slices to view and compare.

The event will be hosted by the Optoelectronics Research Centre (ORC) and the CORNERSTONE Silicon Photonics MPW (Multi Project Wafer) service at the University of Southampton. The ORC is one of the world’s leading institutes for photonics research. Technology…the technology used in an ellipsometer is often not of direct importance – but this technology leads to the characteristics we have already listed such as wavelength range, speed, and accuracy.

Special thanks to Andrew and Jeremy for doing a great job of providing a useful and captivating course that explained everything clearly. Also thanks to Shayz and Angela for organising and helping everything run smoothly, and everyone at Nottingham Trent University for their support and providing a great service. Wave travels from air into absorbing Film 1 and then transparent Film 2. The phase velocity and wavelength change in each material depending on index of refraction (Film 1: n=4, Film 2: n=2). These are industries and activities that have long been associated with Garston - it's well known for its port, which handles roughly 425,000 of imported freight each year - but locals want their community to be about something more than cargo, waste, industry and Heavy Goods Vehicles. Over half of J.A. Woollam employees are scientists and engineers dedicated to the advancement of this single technology. The J.A. Woollam Company possesses a level of expertise in spectroscopic ellipsometry that no other company can match. Our applications engineers have seen almost every ellipsometry application imaginable. This, combined with our versatile product line, allows the J.A. Woollam Company to provide excellent customer support for any application. CompleteEASE is the perfect interface for real-time data acquisition, monitoring, and control. It leverages the vast in-situ spectroscopic ellipsometry experience at

Wavelength range…both the number and range of wavelengths that can be measured are important factors for how well an ellipsometer can solve thin film measurement problems. As a community we are forgotten," says Gary. "In the ECHO in 2018 we were described as Liverpool's forgotten suburb, well we are still forgotten and just getting dumped on all the time."The AutoRetarder is a computer controlled MgF 2 Berek waveplate (compensator) used to accurately introduce retardance into the beam path. Because the compensator is under computer control, it is possible to generate appropriate retardance values (0 – 90°) over a broad (140 – 2500 nm) spectral range. The retardance is automatically adjusted to give the highest measurement accuracy for any sample. Ellipsometry is a self-referencing technique that does not require reference samples to maintain accuracy. Samples smaller than the beam diameter can be measured because the entire beam does not need to be collected. Highly Accurate Measurement SE measurements calculate the change in polarization of light. For real-time measurements, this has significant advantages over intensity-based measurements: where the parameters for Amplitude (A), Broadening (B), Center Energy (E c), and offset (ε 1 off set) are also shown in the figure belowfor a typical Lorentz oscillator. The energy, E, is related to the frequency of a wave, n: The same occurs at each interface where a portion of light reflects and the remainder transmits at the refracted angle. The boundary conditions provide different solutions for electric fields parallel and perpendicular to the sample surface. Therefore, light can be separated into orthogonal components with relation to the plane of incidence. Electric fields parallel and perpendicular to the plane of incidence are considered p- and s- polarised, respectively. These two components are independent and can be calculated separately. Fresnel described the amount of light reflected and transmitted at an interface between materials:

The local community under the bridge in Garston have understandable concerns about the proposal for up to a tenfold expansion of the volume of activity being licensed to be undertaken at Veolia", she explains.The anger is real and if there is no sense that things might change, then it could spill over into something more. From its beginning, the J.A. Woollam Company has dedicated itself solely to the development and refinement of spectroscopic ellipsometry. The J.A. Woollam Company was founded in 1987 in response to commercial demand for ellipsometry technology, which had been studied for decades at the University of Nebraska at Lincoln. Our efforts have led to over 100 patents and numerous awards. Mueller matrix measurements provide the most complete description of the dielectric response of a sample upon interaction with a light source. All J.A. Woollam ellipsometers are capable of collecting Mueller matrix data from a sample. CompleteEASE is not only the engine behind accurate data acquisition, it provides intuitive graphing and analysis tools that help you get the most out of your measurements.

We offer a variety of sample stage mounts to accommodate your measurement needs. Our standard and small sample stages are provided with every ellipsometer, while the others are available as upgrades. Options include: The Mueller-matrix completely specifies the interaction of light from a specular sample. Unlike the Jones-matrix, which can only represent polarized light, the Mueller-matrix can describe polarized, partially-polarized and even unpolarized light. The Mueller-matrix is a 4X4 matrix that describes the reflection or transmission of light, where incoming and outgoing light beams are described by their 4-element Stokes vectors. I'm here for my children and grandchildren," explains Edna. "It's their future I'm worried about, that's why we need to do something."For Patricia - and I suspect many of those gathered at the social club - there should be no limits on what that something could be. "Why don't the people of Garston get out and do something about it," she asks. "I'm 75 and if they aren't going to listen then I think we should chain ourselves to the gates, get out on the streets." In 2021, Veolia wanted to expand its operation at Garston to add new capacity for storing, processing and recycling solvents by a further 28,000 tonnes each year to reach a total of 58,000 tonnes per year. This involved the creation of two fractional distillation towers, a tank farm of 17 tanks, three new cooling towers, a pump house and a new control room. This is not the first time local people have gathered at the club and it won't be the last. There is a growing number of people in this south Liverpool suburb who are increasingly agitated about what is unfolding around them.
