A low magnification projection objective lens for use in projection examination instrument. The projection objective lens comprises three lens units. The first unit is a converging lens unit composed of a positive lens component on the image side and a negative lens component on the object side, ...
of performing photographing by switching the objective lens by setting so as to include the perfocal position of the objective lens attached at the microscope and having a different magnification within the physical depth of focus regulated by the NA of an extremely low magnification objective lens....

The tubes were then vortexed at maximum power at 4 °C for 5 min. The tubes were then centrifuged at 14,000 revolutions per minute at 4 °C for 10 min. The supernatant was transferred to previously prepared HisPur cobalt spin columns (0.2 ml; Thermo Fisher). Protein ...
The equivalent viewing distance would be the original distance divided by magnification, or 0.40 M/4× = 10 cm. The initial lens power would then be +10.00 D, which would be the starting point for determining equivalent powered systems or those systems that would give the same power but in...
Lower-cost implementations have been reported in which the microscope objective is replaced by a camera lens from a mobile phone8, or a ball lens9, but their resolving power is limited by the small numerical aperture (NA) and high aberrations. Of these implementations, the use of mobile-...
