The Bausch + Lomb Optical Microscope is a high-quality microscope. This microscope is known for its precision and reliability, making it a valuable tool for educators, students, and professionals. The included case ensures easy transportation and storage, maintaining the quality and integrity of the microscope for years to come. Ideal for home schooler or really good science teacher who want to showcase science. The box does have some stress cracks as seen in the photos. The microscope itself is untested because it’s been years since I have used a microscope. Feel free to email me with any questions.
