Cyth Develops a Quality Control Microscope to Further Medical Advancements

The medical industry relies heavily on precision, accuracy, and meticulous care when treating patients or performing research. Doctors and scientists need to trust that their medical equipment has been measured precisely and tested to perfection. However, assuring that a medical device performs at a high standard is difficult as the metrics are extremely specific, and what’s being measured is often very small. Yet Cyth was able to create a microscope that operated at the micron level to inspect the quality of tiny glass capillaries used for nano-dispensing, an extremely small yet extremely crucial piece of medical equipment.

Client Request & Cyth’s Solution The client wanted a microscope capable of inspecting small glass capillaries to measure and assure that they are of lab-grade quality. Cyth designed and created a benchtop microscope system with three primary magnifications connected with a camera to inspect the quality of the glass capillaries. The USB-based Basler camera was connected to a computer to view the results of the inspection software, also written by Cyth.

A quality control technician will receive a tray of glass capillaries, marked with a designated lot number with their technical specifications. The technician then loads the capillaries under the microscope to begin examining each one. The designed system is fully automated, so as a technician lines up each glass capillary, the software will automatically calculate both the inner and outer diameter measurements to assure consistency and exact accuracy. The technician is also provided with a live read-out screen with the information presented, allowing them to identify if the capillary passes or fails the quality test. The system calculates a product failure percentage after each round of capillary testing.

Challenge One of the challenges presented was creating sufficient lighting for the microscope. Without proper lighting, the image quality would suffer. Cyth’s engineers had to experiment with multiple lighting sources and lighting filters, from color filters, diffuse filters and a diffuse blue-black light, to find the best combination to improve image quality.

Outcome Automating the system’s ability to measure glass capillaries accelerates the testing process and eliminates inaccurately manufactured products from passing through. The technician can thus run more capillaries and use less labor time. Cyth’s client is striving to create devices used to help cure diseases and treat people in medical care, and they know they must present scientists with the best possible technology and equipment to do so. Cyth was honored to partner with them on this project to help reach their goal of equipping doctors with the tools they need to perform at their best.
