1. What is a cookie?
A cookie is a small text file that is stored in your web browser that allows Coherent or a third party to recognize you. Cookies might be used for the following purposes: (1) to enable certain functions; (2) to provide analytics; (3) to store your preferences; and (4) to enable ad delivery and behavioral advertising.
Cookies can either be session cookies or persistent cookies. A session cookie expires automatically when you close your browser. A persistent cookie will remain until it expires or you delete your cookies. Expiration dates are set in the cookies themselves; some may expire after a few minutes while others may expire after multiple years. Cookies placed by the website you’re visiting are sometimes called “first party cookies,” while cookies placed by other companies are sometimes called “third party cookies.”
2. What cookies are used when I use the Site?
When you use the Coherent Site, Coherent or a third party may place a number of cookies in your browser. First-party cookies are cookies placed and used by Coherent; third-party cookies are those placed by a third party. Some of the cookies will only be used if you use certain features or select certain preferences, and some cookies will always be used. You can find out more about each cookie by viewing our current cookie list. We update this list periodically, so there may be additional cookies that aren’t yet listed.
Each cookie serves one of four different purposes:

4. What are my cookie options?
If you don’t like the idea of cookies or certain types of cookies, you can change your browser’s settings to delete cookies that have already been set and to not accept new cookies. To learn more about how to do this, visit the help pages of your browser. Please note, however, that if you delete cookies or do not accept them, you might not be able to use all of the features we offer, you may not be able to store your preferences, and some of our pages might not display properly.
5. Do you use any other user tracking technologies?
We use additional technologies to help track user activities and preferences. For example, we use web beacons (also known as clear gifs, pixel tags or web bugs). [Note: please confirm this] Coherent does not intentially use web beacons, but a third party vendor may. Web beacons are tiny graphics (about the size of period) with a unique identifier that are embedded invisibly on web pages or emails. They are used to track user activities and communicate with cookies. You cannot opt out of web beacons used in webpages, but you can limit their use by opting out of the cookies they interact with. You can opt out of web beacons used in emails by setting your email client to render emails in text mode only. Finally, we use local storage to facilitate certain functions, but we do not retain the data captured via local storage.
