Matthew Dale asks whether quantum technologies are ready to be seen on the global stage at one of the world’s largest photonics exhibitions
HOLO/OR, a developer of high-power Diffractive Optical Elements (DOE) manufacturing, has announced the release of a family of affordable, reduced cost, microscopy vortex phase plates
This paper demonstrates various options in digital microscopy to enlarge the object size yet maintain the original resolution. It will discuss and compare various methods, emphasising the advantage of Omek Optics solutions with consideration to the formats and pixel size of the imaging camera and the optical layout of the microscope.
