Microscope Lens Design. To build your microscope. place the lens identified as the eyepiece (ocular) lens on the end of the cardboard tube having the smallest diameter. In this microscope’s optical design. the objective creates the image at infinity and a new optical element called the tube lens creates the intermediate image that is picked up by the eyepiece.

The first step is to place the object between the single and double focal point. The microscope objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image.

The Optical Microscope. Often Referred To As The “Light Optical Microscope.” Is A Type Of Microscope That Uses Visible Light And A System Of Lenses To Magnify Images Of Small Samples.
The result is a magnified. real image. To build your microscope. place the lens identified as the eyepiece (ocular) lens on the end of the cardboard tube having the smallest diameter. Microscope objectives are typically composed of multiple.
The Lens Material Is Made Of A Mouldable Plastic Material (N=1.53) And Both Surfaces Are Made Aspherical Such That An Aplanatic Design Can Be Realised.
To design the tube lens. begin by opening a new file and opening zemax design templates and opening microscope objective 60x (or file example k_007 previously in zebase. see the help files section the libraries tab design templates group design templates for more details). The system is designed in two major parts: With a drop of water as a lens.
