Here are some tips for the visually impaired. The Laser Systems Branch web site uses three frames.
All images reside on a star field background.
A couple of spacers are used to get things to line up properly. Selections chosen from the menu in the third frame will appear here. The right frame contains the main menu . For each item in the menu there is an icon and a text title, both of which are links which will take you to the same page. They have a header and a footer and appear in the center frame.
