Leica Optical Coherence Tomography (OCT) systems support ophthalmologists, ophthalmic surgeons, and researchers with easy-to-use, high-quality imaging technology.

Optical coherence tomography (OCT) is an imaging technology with applications in biology, medicine, and materials investigations. In a clinical environment, OCT has revolutionized the clinical practice of ophthalmology by providing 3D anatomic information. In preclinical research, OCT facilitates early stage research into pathology and drug discovery. This non-invasive technique is used to detect and monitor morphological changes of ocular tissue, in particular retinal layer thickness, which may aid in the diagnosis of certain pathological conditions such as glaucoma, age-related macular degeneration (AMD) or diabetic retinopathy. In this Sciecne Lab topic you can find basic information about OCT, articles with application examples, case studies, and links to selected publications.

MLD has developed a comprehensive capability to design, manufacture and measure Ultrafast Optics. We have longstanding design experience managing Group Delay Dispersion (GDD) in all types of coatings, including mirrors, polarizers and beamsplitters.* We collaborate with customers to understand their GDD specifications in the context of compensating the whole optical system.

MLD has substantial experience measuring GDD at wavelengths between 940 and 1090 nm. Historically it has been difficult to perform accurate, high resolution metrology in this wavelength region. MLD has built a custom white light interferometer system that enables us to reliably and precisely measure what we make. GDD values obtained with our system have an uncertainty as low as ± 10 fs2, and a wavelength resolution of 0.5 nm. Precision calibration against other state-of-the-art commercial and institutional measurement systems further ensures that customers can count on our measurement data.
