The choice of the objective focal length is imposed by the required field-of-view (FOV) in the direction parallel to the slit.
As a result, excitation spots can be located within all the available excitation field available, i.e. <img src="http://journals.plos.org/plosone/article/asset?id=info?doi/10.1371/journal.pone.0009431.e001.PNG" class= inline-graphic"/>, where d is the spatial frequency corresponding to the maximum deflection angle from LCOS-SLM and fobj the objective focal length.
Objective: Length of sperm exposure has been proposed to influence the risk of preeclampsia.
In this case, as far as we are aware of, there is no previous evidence that the objective text lengths are represented mentally on a logarithmic scale.
The magnification of the system is given by the ratio of the detector lens focal length to the objective lens focal length, Mag = fdet/ fobj = 22.
Solving the coupled lens equations for this system we obtain, <img src="http://journals.plos.org/plosone/article/asset?id=info?doi/10.1371/journal.pone.0016772.e022.PNG" class= inline-graphic"/> where fO is the objective effective focal length, fT is the tube lens focal length, and L is tube length.
The overall magnification is given by the objective, the focal length f1 of the tube lens L1, the position and the focal length f2 of lens L2.
The magnification, sometimes referred to as magnifying power, is determined by dividing the focal length of the objective by the focal length of the eyepiece.
Once you have the focal lengths for both of your lenses, solving is easy — just find the ratio by dividing the objective's focal length by the eyepiece's.
During the design optimizations, specific energy absorption (SEA) is set as the design objective, side length of the cross-sections and wall thickness are selected as design variables, and maximum crushing force (Pm) is set as the design constraint.
