When Bilhah conceives two sons, Leah takes up the same idea and presents Zilpah to wife to Jacob. Leah names the two sons of Zilpah and is directly involved in their upbringing.Pirke De-Rabbi Eliezer, xxxvi.). Zilpah also figures in the competition between Jacob's wives to bear him sons. Leah stops conceiving after the birth of her fourth son, at which point Rachel, who had not yet borne children, offers her handmaid, Bilhah, to wife to Jacob so that she can have children through her.
What is a Confocal Microscope? A confocal microscope performs the same function as any other microscope. Itâs used to view any objects or structures that are too small for the naked eye to see. Unlike the traditional light microscope, however, a confocal microscope slices thin, clean optical sections of a given specimen using either fluorescence or reflection.
A binocular microscope has one optical path starting at the microscope objective. The optical path is split into two paths that are then brought to your eye. If your microscope has two eyepieces and one standard objective then you have a binocular microscope.A trinocular microscope works in the same manner, but the optical path is split into three paths, two for your eyes and a third port mostly used for a video/camera connection.In a stereo microscope, there are two paths starting at the microscope objective that travel parallel up to your eyepiece.There is an advantage to using a stereo microscope; it is the depth perception.f your microscope has two eyepieces and one standard objective then you have a binocular microscope. A trinocular microscope works in the same manner, but the optical path is split into three paths, two for your eyes and a third port mostly used for a video/camera connection.
