Acousto-Optic Components Overcome Limitations in Confocal Microscopy
Acousto-Optic Components Overcome Limitations in Confocal Microscopy
Confocal and multiphoton microscopy are commonly used to provide 3D-resolved images of in vitro or in vivo tissue samples without physical sectioning. But there are also inherent trade-offs in the use of these techniques when it comes to imaging depth, resolution, and speed. Recent developments in the use of acousto-optic and other photonic components integrated into a microscope are beginning to address these limitations in capability, opening up new opportunities in life science research.

Top Hat Illumination Provides Even Light Distribution Across Samples
Top Hat Illumination Provides Even Light Distribution Across Samples
Two common illumination techniques used in microscopy are known as critical illumination and Köhler illumination, and each has advantages and disadvantages. Other lighting techniques are also available for a variety of biophotonics applications. A new lighting method that uses lenses with LEDs to produce flat, top hat illumination has emerged, yielding even distribution of illumination across any plane of interest. This approach greatly benefits life scientists who examine dynamic and intricate samples.

Pump Laser Modules Show Promise for Ophthalmologic Treatments
Pump Laser Modules Show Promise for Ophthalmologic Treatments
Researchers at the Berlin-based Ferdinand-Braun-Institut (FBH) developed a pump laser module for ophthalmologic treatments. The module offers a cost-effective pump source for laser systems that are used to treat retinal detachments. The miniaturized module can be flexibly adjusted to provide the optimal wavelength for its intended application. The semiconductor-based, miniaturized laser module could provide a reliable, efficient way to provide laser surgery that is targeted to the condition being treated and could reduce the costs of ophthalmologic laser surgery.

Technical Advancements in Line-Field Confocal Optical Coherence Tomography for Improving the Management of Skin Cancer Technical Advancements in Line-Field Confocal Optical Coherence Tomography for Improving the Management of Skin Cancer
Tue, Feb 28, 2023 10:00 AM - 11:00 AM EST
Line-field confocal optical coherence tomography (LC-OCT) is an imaging technique based on a combination of reflectance confocal microscopy and time-domain OCT. It can generate cellular-resolution vertical images, horizontal cross-sectional images, and three-dimensional (3D) images, yielding the possibility for optical biopsies of skin tissue in vivo and in real time. Jonas Ogien, Ph.D., of DAMAE Medical introduces the basic principles of LC-OCT and shares an overview of new technical advancements based on the technique.
