Description

The Focal Microscope was a house branded product from Kmart which was a rebranded product originally manufactured in Japan. The Focal Microscope from Kmart was a mass-market educational microscope sold during the mid-to-late 20th century as part of Kmart’s affordable science kit line. Designed for beginners and young students, it typically offered magnification levels around 100×–300× and came with basic tools for viewing prepared slides. Although not a professional laboratory instrument, it introduced many users to hands-on scientific observation at a low cost. Today, it’s considered a nostalgic example of accessible consumer science equipment from big-box retail stores.

ID: A basic education microscope with a seafoam green colorway. The microscope was constructed with a metal base and upright arm. It has a black eyepiece tube at the top, a rotating silver nosepiece with two or three short objective lenses, and a flat black stage with metal slide clips. Below the stage is a small mirror used to reflect light upward. Also, the focusing knobs are positioned on the side of the microscope arm, roughly halfway between the eyepiece and the stage.
