Medical Technology

Optics enable precise imaging in medical technology, for example in endoscopy and dental scanners.

In medical technology, optics are used in a wide range of applications. This includes endoscopy with flexible or rigid instruments for examining the inside of the body. Optical systems are also used in medical imaging, for example in dental scanners, to produce detailed images of the oral cavity.

Our solutions for medical technology

It enables minimally invasive visualization, diagnostics, and therapy within the human body, supporting medical professionals with high-resolution imaging and precise, minimally invasive procedures.

  • Gastroscopes: are flexible endoscopes for examining the upper gastrointestinal tract. They enable precise visualization of the esophagus, stomach, and duodenum and support both diagnostic and therapeutic procedures.
  • Colonoscopes: are used to examine the colon and are a central instrument in modern colon diagnostics. Thanks to high-resolution imaging, they enable early detection of abnormalities and the performance of minimally invasive treatments.
  • Duodenoscopes: these are specialized endoscopes for procedures involving the bile and pancreatic ducts. They are used particularly in endoscopic procedures such as ERCP and support demanding diagnostic and therapeutic applications.
  • Bronchoscopes: enable examination of the airways and bronchial system. They provide an excellent view of airway anatomy and support diagnostics, tissue sampling, and various therapeutic procedures.
  • Cystoscopes: are used to examine the urethra and bladder. Their high degree of maneuverability enables gentle diagnostics and contributes to improved patient comfort.
  • ENT endoscopes: are used to examine nasal, pharyngeal, and laryngeal regions. They provide detailed insights into anatomical structures and support precise diagnostics in otorhinolaryngology.

They offer the highest image quality and level of detail for diagnostic and surgical applications. Unlike flexible endoscopy, they are primarily used for minimally invasive procedures with direct access to the treatment area and enable precise visualization of anatomical structures.

  • Laparoscopes: are used in minimally invasive surgery and enable diagnostics and procedures in the abdominal cavity through small incisions.
  • Arthroscopes: are used for the minimally invasive examination and treatment of joints such as the knee, shoulder, or hip. They enable precise visualization of structures such as cartilage, ligaments, and menisci.
  • Laryngoscopes: enable the visualization of the larynx and vocal cords. They are used both in diagnostics and during surgical procedures.
  • Hysteroscopes: are used for the examination and treatment of the uterine cavity. They enable minimally invasive diagnostics and targeted therapeutic interventions in gynecology.
  • Ureteroscopes: are used for the examination and treatment of the ureters. They enable precise diagnostics as well as minimally invasive therapy for urinary stones and other conditions.
  • Otoscopes: used to examine the external auditory canal and eardrum. They are an essential instrument in ENT diagnostics.

3D endoscopy enhances traditional endoscopy by providing realistic depth perception and a spatial representation of the surgical field. This significantly improves orientation, precision, and ergonomics during minimally invasive procedures. It supports precise interventions in the fields of laparoscopy, thoracoscopy, gynecology, urology, ENT surgery, and neurosurgery.

  • 3D laparoscopes: enable realistic spatial visualization of the surgical field and support the highest precision in minimally invasive procedures in the abdominal cavity.
  • 3D Thoracoscopes: improve intrathoracic orientation and support complex thoracic surgical procedures through optimized depth perception.
  • Gynecology: 3D endoscopes provide precise spatial visualization of gynecological structures and support demanding minimally invasive procedures.
  • Urology: In urology, 3D endoscopy supports precise visualization of anatomical structures and increases the precision of complex surgical procedures.
  • ENT surgery: 3D endoscopes improve spatial orientation in complex anatomical regions and support precise procedures in the ear, nose and throat field.
  • Neurochirurgie: Die 3D-Endoskopie ermöglicht eine detailreiche räumliche Darstellung sensibler anatomischer Strukturen und unterstützt höchste Präzision bei neurochirurgischen Eingriffen.

Micro-optics are used in dental cameras to capture high-resolution images of the oral cavity for diagnostics, documentation, and patient communication. By employing micro-optics, dental cameras can be compact while still capable of capturing clear and detailed 2D or 3D image information.

  • Intraoral scanners: capture the dental and oral situation directly in the patient’s mouth and create highly precise digital 3D models. They enable comfortable, fast, and impression-free data acquisition for diagnostics, treatment planning, and dental prosthetics.
  • Laboratory scanners: digitize plaster models, impressions, or prosthetic work in the dental laboratory. They provide the foundation for precise CAD/CAM processes and the digital manufacturing of dental prostheses.
  • Model Scanners: specialize in the highly accurate acquisition of dental models. They enable detailed digitization for planning, analysis, and documentation.

Telemedicine devices enable patients to capture high-resolution images of their conditions and transmit them directly to the physician or specialist. In telemedicine, micro-optics play an important role in capturing and transmitting high-quality medical images to enable remote treatment and diagnosis. Here are some areas in which they are used:

  • Tele-otoscopy: for medical examinations of the ear, specifically the external auditory canal and the tympanic membrane.
  • Teledermatology: for capturing skin lesions or skin conditions
  • Tele-ophthalmology: for capturing detailed images of the fundus in ophthalmology
  • Tele-endoscopy: for the medical examination of the airways or other body cavities
