Conduct your studies using the Barska AY13072 Monocular Compound Microscope. This handy optic features three objectives (4x, 10x, and 40x) and a widefield 10x eyepiece to deliver up to 400x of magnifying power. For comfort and convenience, its monocular head is inclined 45° and rotates 360° to allow sharing the microscope with your friends, classmates, or colleagues. To ensure that you obtain bright images, the base of the scope houses a 5W halogen illuminator with adjustable brightness. You can secure your samples on a square 4.7 x 4.7" stage using two spring-loaded clips, adjust working distance, and use fine and coarse focusing to obtain sharp images. For precision and durability, the frame is made of cast aluminum with some copper parts and offers a solid back that can be used as a handle.
