Open a file in finder with script

I am having instructions for actions in pdf-files. Trying to make a script that opens a specific folder in OSX Finder (/Application/Adobe Photoshop CS6/Instructions/FileNameHere).

Is this possible. One alternative is to only have the script switch to finder and show the folder. Or if its possible also open all files in that folder (but that may not be neccessary if its hard)

Any ideas?
