The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to the field of optical instruments, particularly compact and portable microscopy systems. It discloses a closed-tube optical microscope constructed using a rigid cylindrical PVC enclosure aligned along a common optical axis. The system comprises a removable, modular objective lens detachably mounted at the proximal end, an integrated illumination source at the distal end, and a centrally positioned movable slide stage located between them. The stage enables controlled specimen positioning within the enclosed optical path. The tubular body may further include a telescopic or collapsible configuration to enhance portability and compact storage. The invention provides a purely optical imaging system without reliance on digital sensors or electronic displays, thereby reducing cost, complexity, and maintenance while improving durability, optical alignment, and suitability for field, educational, and low-resource applications.
