Or it would let you use an optical zoom with two different angles.
Film thickness was measured by microscopic analysis, using an optical microscope (STM-902 ZOOM, Opting, CZ) and NIS Elements software.
Microscopic properties of the prepared films were evaluated using an optical microscope (STM-902 ZOOM, Opting, Czech Republic) and a color digital camera (DFW X700, Sony, Japan).
Film thickness was evaluated by microscopic analysis using an optical microscope (STM-902 ZOOM, Opting, CZ) and colour digital camera (DFW X700, Sony, JPN).
A control on the power deposition width will be achieved by changing the beam radius in the plasma using an optical system composed by two mirrors (zooming range 17 28 mm).
Optical observation of the pair of growing drops was achieved by the use of an optical zoom lens system for a side view, and a "long-range" microscope for a top view, thus ensuring complete alignment of the capillaries and partial observation of the thin-film.
Images were obtained on a Zeiss LSM510 Meta confocal laser-scanning microscope (Carl Zeiss, Oberkochen, Germany) using a 63× 1.4 NA PlanApo lens at an optical zoom of 3×.
The premium model, called the DEV-5, has an optical zoom that can magnify a subject 10 times, or you can use the digital zoom to increase the magnification to 20x.
PURCHASING I just purchased an optical zoom telephoto lens that fits onto my iPhone 5.
Others offer an optical zoom on the projection lens itself.
