Oxford Instruments plc, registered in England with the company number 775598 at Tubney Woods, Abingdon Oxon, OX13 5QX, UK, uses cookies and similar technologies on this website.

This page describes how our website uses these cookies and technologies to improve the visitor experience and how you can manage which cookies are placed on your computer.

What are cookies?

Cookies are small text files which are transferred from our website and stored on your computer. They are widely used in order to make websites work, or work more efficiently, as well as to provide general usage information to website owners. Cookies will only contain and transfer as much information as you have shared with a website.

Similar to cookies, HTML5 local storage stores information on your device and can record some information about your activities and preferences.

In addition to cookies, we also use web beacons and pixel tags on this website. Web beacons and pixel tags are embedded into a website or email to help identify your device cookies when you browse the website or email and let us know whether you have opened the email or not. We use this information to help us learn about your preferences and to improve our offerings. You can unsubscribe from our emails if you do not want to be tracked via emails.

Are any of these cookies necessary?

Yes. Some of the cookies we set are absolutely necessary for the operation of our website. Without them the website would simply stop functioning. We have listed these as ‘Essential cookies’ in the table below. You cannot disable our essential cookies.

How can I manage other types of cookie?

Not all cookies are essential. An explanation of the purpose and benefit of all of the other cookies used on our website is provided below. We need your consent to use any non-essential cookies and you can update your preferences at any time.

The cookies we use…

Functional Cookies

What are essential cookies, and can I disable them?

These cookies allow our website to provide you with the basic features and normal website behaviours, and to remember the choices you make. Examples include basic functions such as page navigation and access to secure areas of the website. We use these cookies as we believe it is in both our and your legitimate interests to enable the site to function properly.

Whilst it is possible to set your browser to block or alert you to these cookies, some parts of the website will not work without them.

What data do they collect and use?

Essential cookies seldom collect and use any personal data, though they may contain an ID code which allows the website to distinguish you as an individual visitor from all other visitors on the website at the same time. These unique ID codes are used to maintain a server session to enable functions you have requested.

How long is this data retained?

Essential cookies are typically session cookies and therefore only retain data for the duration of your visit to the website.

Is this data shared with third parties?

We use third party website infrastructure suppliers to help us build and manage our website. Cookie data is stored securely on these suppliers’ servers.

Analytical Cookies

What are Analytical Cookies, and can I reject them?

These cookies collect general information about how visitors access and use our website to help us improve our website for everyone. For example, we track which pages visitors go to most often and if they get error messages or broken links. These cookies don’t collect personal data that identifies a visitor. All the information these cookies collect is aggregated and therefore anonymous.

However, the third parties providing these services will process your personal data in order to provide the aggregated data.

Why do we use analytical cookies?

We use these cookies to enable measurement and analytics. They help us to improve the onsite experience you have and ensure we better meet your needs. From analytics we can understand the journey you took to get to our website and where you went on our website. It helps us understand what pages are most popular and which are not, which informs our future decisions when developing new content. We can gather information about the devices used and the search engines used to make sure we are optimised for these platforms and can be easily found on these search engines. We use all this information to help inform our future decisions regarding market trends, content development and customer needs.

What data do they collect and use?

The cookies will normally just record an ID code. However, this ID code links to the server of the analytics provider, such as Google, CommuniGator or CrazyEgg, enabling them to build a profile of how you browse the website. Browser details are processed as a result of the cookie being read.

We do not collect any personal data through analytical cookies – we only receive aggregated data about our website visitors in general. However, Google, CommuniGator and CrazyEgg do process your personal data in order to provide these aggregated statistics to us. Further, as other websites also use Google Analytics, Google doesn’t just have a profile of how you use our website but also how you use many other websites which also use Google Analytics. To learn more about how Google processes your personal data, please refer to Google’s Privacy Policy.

These cookies are only set on your device if you agree to them when you first visit our website, and you can subsequently reject marketing cookies at any time by changing your cookie settings.

Why do we use advertising cookies?

We use advertising cookies to help us build a profile of your browsing behaviour so we can show advertisements that are most relevant to you. We use social media cookies so that you can ‘like’ or ‘share’ our content.

What data do they collect and use?

Advertising cookies store unique IDs that are associated with a profile on our advertising partners’ servers. These profiles record your browsing behaviour and actions linked to your browsing information, such as actions you take on the site, and technical specifications about your device and location. Google’s advertising cookies may also link to Google ID, if you are logged into your account while on our website, building a more detailed profile about you.
Social media cookies collect your IP address and browser string and send this back to the site that embedded the cookie, allowing social media sites to recognise that you have visited our site. This applies irrespective of whether you have an account with that social media site.
Any personal data shall be processed in accordance with our privacy policy.

How long is this data retained?

The retention period of marketing cookies varies from 24 hours to 24 months depending on the purpose of the cookie.

Is this data shared with third parties?

We use third party website infrastructure suppliers to help us build and manage our website. Cookie data is stored securely on these suppliers’ servers.

We use advertising cookies set by a number of third parties, including Google, Facebook, Twitter, YouTube and LinkedIn. Oxford Instruments is a joint data controller with these companies because we choose to implement their cookies on our website, enabling those third parties to collect data about you when you visit our site.

To learn more about how they process your personal data, please refer to their privacy policies. Google, Facebook, Twitter and LinkedIn are all EU-US Privacy Shield-certified organisations.
