Optical Coherence Tomography (OCT) is a technique that utilizes low coherence optical interference to create noninvasive 3D images of biological tissue in real time. The initial rapid growth of OCT was driven by ophthalmic applications, particularly the unique ability to image the layers of the eye’s retina “in vivo”, and it is now being applied to the biometric measurement of the eye’s anterior segment (cornea and lens), significantly improving treatments such as cataract replacement. The technique is now being applied to imaging of the skin, artery walls, the esophagus and other tissues for clinical diagnostics and as an alternative to biopsy. High quality, performance and reliability has made G&H a leading supplier for OCT ophthalmology instrumentation, providing the fused fiber couplers, interferometers, and collimators used in many commercial systems. Exacting control over our manufacturing processes ensures highly repeatable performance and tight performance distributions for all of our OCT components and subsystems.

宽带OCT耦合器

G&H OCT延迟线
OCT耦合器
光纤耦合器用于光学相干断层扫描(OCT)光发动机,以形成OCT系统用于生成深度信息的干涉仪。虽然传统的视网膜扫描系统可以使用具有〜30nm的带宽的光源,但最新一代OCT系统正在移动到> 100nm带宽以提供更高分辨率的图像。作为响应,G&H开发了极其宽带光耦合器(E亚搏开户网址WOC),提供了超过140nm波长范围内的市场领先性能,以用于采用下一代宽带波长扫描源的高分辨率OCT成像系统。EWOC(极端宽带OCT耦合器)在扩展带宽上分配,并且可以在流行的OCT波长(850nm,1060nm和1310nm)的任何一个下方操作。耦合器专为低损耗和扩展带宽操作而设计,利用G&H专有的融合光纤技术.

Delay lines

G&H OCT延迟线
G&H OCT延迟线
The G&H variable optical delay line provides fast and accurate optical path length change in a compact housing. Based on a point-and-return architecture with a customizable chassis that can be adapted to incorporate additional optical components, the unit is designed to be easily incorporated into any modular optical coherence tomography (OCT) system architecture. Optical interface is through single fixed fiber pigtail which can be specified to any length and terminated with all commonly used optical connectors.

Collimators

FIber Optic Collimator
FIber Optic Collimator
G&H offers a range of non-contact style, single mode, fiber collimators incorporating achromatic lenses. Anti-reflection coatings are employed to minimize back reflections. G&H’s proprietary alignment and assembly processes produce a beam having low pointing error that is stable over a wide range of environmental conditions.
G&H OCT fiber collimators are manufactured to high opto-mechanical tolerances to enable simple incorporation into production line processes.
