Optical Coherence Tomography (OCT) is an advanced imaging technology that uses light waves to produce high-resolution, cross-sectional views of biological tissues. It plays an important role in fields like ophthalmology, dermatology, and cardiovascular research. Edmund Optics supports OCT system development with a wide range of advanced optical components. These include polarization optics for accurate light control, non-polarizing beamsplitters for efficient interferometer design, laser mirrors for precise beam steering, and OCT phantoms for system calibration. Our broadband light sources provide excellent image resolution and depth, while motorized translation stages, active optical components, and galvanometers enable fast, accurate scanning. Together, these technologies drive superior imaging performance and accelerate biomedical research and diagnostics.

Polarisationsoptiken

Polarisationsoptiken

Polarisationsoptiken steuern die Ausrichtung des elektrischen Feldes des Lichts und bieten leistungsstarke Möglichkeiten sowohl für das Computational Imaging als auch für astronomische Beobachtungen. Durch den Einsatz von Komponenten wie Polarisatoren und Verzögerungsplatten zur Manipulation und Messung von Polarisationszuständen können diese Systeme den Kontrast verbessern, Blendeffekte reduzieren und Informationen offenbaren, die durch Intensität oder Wellenlänge allein nicht zugänglich sind. In der industriellen Bildverarbeitung ermöglicht dies eine verbesserte Merkmalserkennung und Materialanalyse, während in der Astronomie Wissenschaftler bei der Untersuchung der Interaktionen von Licht mit Staub, Magnetfeldern und Planetenatmosphären unterstützt werden, um die Umgebung der Himmelskörper besser zu verstehen.

Nicht polarisierende Strahlteiler

Nicht polarisierende Strahlteiler

Non-polarizing beamsplitters divide light in OCT interferometers into reference and sample arms at a defined ratio (e.g., 50:50) and preserve the polarization state. They transmit and reflect both s- and p-polarized light equally, ensuring consistent interference signals and minimizing polarization artifacts. These beamsplitters provide accurate beam recombination and stable detection, supporting precise depth-resolved measurements in OCT.

Optotune Beam Shifters

Aktive optische Komponenten

Aktive optische Komponenten nutzen elektrisch betriebene Mechanismen wie einstellbare Fokussierung und adaptive Reflexion zur Steuerung von Beleuchtung und Wellenfrontverhalten und vereinfachen so das Systemdesign. Edmund Optics bietet Flüssiglinsen, variable Diffusoren, Speckle-Abschwächer und adaptive Optiken, die eine schnelle Kontrolle über Fokus und Aberrationskorrektur ermöglichen. Diese Funktionen verbessern das Computational Imaging, indem sie eine umfangreichere Datenerfassung und Wellenfrontformung in Echtzeit für eine nahtlose Integration in die algorithmische Rekonstruktion ermöglichen.

Galvanometer

Galvanometer

Mit Umlenkungsspiegeln und optischen Scannern können Sie Ihren Messungen zusätzliche Dimensionen hinzufügen oder Proben effizienter bearbeiten. Die Proben werden oft seitlich oder sogar axial gescannt, so dass Querschnitte entstehen, die, wenn sie übereinandergelegt werden, hochauflösende Details liefern.

25mm Travel, Motorized Linear Stage, Integrated Controller, #15-285

Motorisierte Bühnen

Motorized translation stages in optical coherence tomography (OCT) provide precise, programmable motion control essential for both lateral and axial scanning, enabling high-resolution imaging, automated point-by-point acquisition, and volumetric reconstruction. They ensure accuracy, repeatability, and smooth focus adjustments, allow imaging over large areas through mosaic stitching, and facilitate complex scans across curved or irregular surfaces when integrated with robotic and feedback systems. High-precision stages, including stepper-motor or piezo-driven designs, maintain consistent alignment, handle OCT instrumentation, and support dynamic tracking, making them a critical component for OCT’s practical and clinical capabilities.

Fiber Coupled Laser-Driven White Light Source

Beleuchtung für Spektroskopie

Edmund Optics’ light sources, including superluminescent diodes (SLEDs), swept-source lasers, and broadband sources, are ideal for optical coherence tomography (OCT) because they combine broad spectral bandwidth with short coherence length, enabling high axial resolution and precise tissue imaging; SLEDs provide stable, low-noise output for micrometer-scale resolution, swept lasers allow deep tissue penetration and rapid acquisition for real-time imaging, and broadband sources maximize depth resolution and spectral flexibility; together, these sources enhance signal-to-noise ratio, support noninvasive imaging across varying tissue types, and integrate seamlessly into OCT interferometers to produce detailed 2D and 3D images, making them highly suitable for ophthalmic, cardiovascular, and dermatological applications.
