The OCT tag gathers content related to Optical Coherence Tomography and other optical tomography techniques that demand high-precision optics and careful system design. Articles discuss OCT scan lenses, beam splitters, and collimators that must meet strict tolerances for wavefront quality and dispersion control to deliver micron-scale resolution and low-noise images in tissue and materials. Readers also find resources on related technologies such as diffuse optical tomography, which uses near-infrared light to visualize absorption and scattering in soft tissue, as well as micro- and nano-scale 3D printed microlenses that can be integrated into OCT and biomedical imaging setups. Topics include aberration control, material and coating selection, and the challenges of manufacturing OCT components that maintain performance over time. For engineers and scientists working on ophthalmic systems, biomedical imaging instruments, or industrial OCT metrology, this tag offers insight into how optimized optics drive image contrast, resolution, and system reliability. It also reflects Avantier’s expertise in designing and manufacturing the critical optical elements that make advanced OCT systems possible. [avantierinc]
Optical Coherence Tomography (OCT) is a powerful, non-invasive imaging technique that delivers real-time cross-sectional views of biological tissues; the ability and micrometer-scale resolution rely heavily on the quality and precision of its optical components.
Diffuse Optical Tomography (DOT) is a medical imaging technique that uses NIR light to measure the optical properties of biological tissue. By analyzing light absorption and scattering from chromophores like hemoglobin, it enables non-invasive, real-time imaging of tissue oxygenation, composition, and functional activity.
Micro and nano scale 3d printing is an advanced additive manufacturing technique that builds optical microstructures layer by layer, overcoming the limitations of traditional microlens manufacturing methods by offering exceptional resolution, customization, and rapid production capabilities.
