About this clipart
This black-and-white technical illustration depicts a cross-sectional view of an early 20th-century optical instrument, likely a camera obscura or projection device, featuring a curved lens (7), rigid housing (10/10′), and adjustable mounts (6, 9). Components such as the threaded adjustment knobs (8) and internal support rods (5) suggest fine-tuning capability for focus or alignment. The hatched vertical member (11) appears to be a structural or light-blocking element.
Used in patent documentation, engineering education, or historical tech archives; serves users researching optical instrument evolution, mechanical design, or intellectual property history.
