How about getting her a high-quality microscope kit she can use to further explore her interest in microscopy? It's a great way for her to study anything she finds interesting at a microscopic level. In addition, you can add a book on microscopy so she can learn more about the topic. Some other ideas may include a subscription to a magazine specializing in microscopy, or a visit to a science museum with an exhibit on microscopy. Another idea could be a personalized pendant or bracelet that features a microscope charm or design.
Or you can get her a star map with the date of your anniversary.
