Endoscopes

Endoscope optics are at the core of who we are and how we came to be in the optics industry. The first device created by Sunex was a laparoscope, nearly thirty years ago. Since then, endoscope technology has advanced greatly, and our optics technology has progressed alongside it. A few of the recent endoscopy projects we have had the fortune of working on include both single-use and reusable colonoscopes, laparoscopes and duodenoscopes. We believe specialty and single-use endoscopes are the future of the industry.

Traditionally, endoscopes were expensive and required meticulous sterilization after each use. However, the advent of single-use endoscopes has revolutionized the medical landscape, offering advantages for patients and providers alike. With streamlined service, increased patient safety, reduced costs and reduced environmental impact, single-use is the future of endoscopy.

While there are numerous advantages, designing and manufacturing these endoscopes comes with plenty of challenges as well. Sunex is proud to have brought multiple single-use endoscopes to market, navigating the balance between cost effectiveness and high performance.

If a lens can couple a large FOV and low distortion, in a small package, it is the ideal candidate for the future of endoscopy.

Diagnostic Imaging

Imaging has been at the cornerstone of diagnostics since the discovery of X-rays in the late 1800’s. By enabling providers to non-invasively observe their patients, countless lives have been saved. At the heart of this field are premium optics. High quality optics ensure superior image clarity and resolution. This is crucial as it allows healthcare professionals to see fine details, such as minute lesions, microcalcifications or subtle changes in tissue composition. An increased accuracy in diagnostics can improve treatment plans as well, helping to precisely identify cancerous tissues which need to be removed so that healthy tissues remain unharmed.

Sunex is proud to have had the opportunity to work on the development of a number of diagnostic devices, from portable X-ray machines to point-of-care disease detection devices. Across all applications precision and consistency is at a premium and thus these opportunities have led to the development of some of the most accurate, low distortion lenses in our catalog. 

By delivering athermalized, low distortion and high-resolution lenses, Sunex has been grateful to play a role in the diagnosis and treatment of many medical maladies and we look forward to innovating again.

Robotic Surgery

The future of robotic surgery is incredibly promising. As technology continues to advance, it is expected that the application of robots in surgery across nearly all disciplines will greatly increase. Some of the advancements that are primed to enable this increased adoption include enhanced vision capabilities and ever shrinking devices to make surgery as minimally invasive as possible. 

With a large catalog of high quality, miniature lenses, Sunex is excited to offer assistance to innovators creating the next generation of surgical robots.

We have worked with leading companies to create ultra-small, high resolution and wide FOV lenses that currently reside in surgical systems. These range from the endoscopes that capture images to the immersive vision systems that relay these images to surgeons and a range of visual applications in-between. By giving providers an increased FOV and Depth of Field over other lenses, Sunex lenses ensure the entire area of operation can be viewed clearly.
