Over on YouTube [Applied Science] shows us how to make an f/0.38 camera lens using an oil immersion microscope objective. The f-number of a lens indicates how well it will perform in low-light. To ...

This case study examines the high numerical aperture (NA) infinity conjugate long working distance microscope objective, suitable for precision applications such as optical tweezers. The microscope ...

A global leader in agricultural genetics sought durable, economical UV microscope objectives. Issues in meeting these objectives included optical design complexity, wavefront control, and fabrication ...

Ghost imaging is like a game of Battleship. Instead of seeing an object directly, scientists use entangled photons to remove the background and reveal its silhouette. This method can be used to study ...

This valuable study builds on previous work by the authors by presenting a potentially key method for correcting optical aberrations in GRIN lens-based microendoscopes used for imaging deep brain ...

Constructed with precision optical lenses, high-quality materials, a variety of illumination choices and a trinocular eyepiece tube, Celestron Labs has created a promising instrument for advanced ...

For centuries, scientists have used microscopes to magnify and peer into a world invisible to the naked eye. The earliest instruments were simple lens-filled tubes, the best of which revealed the ...
