     DESCRIPTION 
       [0022]    The present disclosure generally relates to a device for fastening imaging units to an eye piece of an optical system. 
         [0023]    The devices of the present disclosure, according to one embodiment, may be capable of fastening a variety of imaging units to an optical system that is easy to manipulate, that is not restricted to specific imaging units nor restricted to specific optical systems, and at the same time can be produced cost-effectively with a minimum of components. The devices of the present disclosure, according to certain embodiments, may be used with any optical system such as, for example, microscopes, telescopes, binoculars, monoculars, spotting scopes, and the like. While in certain embodiments the present disclosure describes a universal mount, the present disclosure contemplates devices adapted for use with specific imaging units in which case the need for a platform that moves with respect to the adapter component may be reduced or minimized and a static platform may be employed. For example, the device present disclosure may be used with a specific phone, in which case the need for translation in all axes may be reduced and the platform may be fixed with respect to the adapter component. 
         [0024]    In certain embodiments, the platform may comprise mounting features specific to one imaging device, such as a smartphone. In yet other embodiments, the platform may be shaped to encase a smartphone with specific dimensions and affix the smartphone to the adapter component. In yet other embodiments, the platform can be fixed with respect to the adapter such that the imaging unit on a smartphone is aligned with the optical axis an optical system. In yet other embodiments, the platform can be attached to and released from the adapter component with a variety of mechanisms. 
         [0025]    In certain embodiments, the device may attach to any cylindrical shaped component of the microscope such as an eyepiece, a lens tube, or a portion of the microscope housing. 
         [0026]    This object may be achieved by a device that in certain embodiments comprises an adapter component ( 4 ) surrounding a cylindrical component of the optical system ( 1 ) such as an eyepiece of a microscope, a platform ( 2 ) that moves with respect to the adapter component ( 4 ) and provides a mounting surface for an imaging unit ( 3 ) such as a cellphone.  FIGS. 1-11  illustrate embodiments of such devices. The adapter component ( 4 ) can be moved up and down along the cylindrical component on optical system ( 1 ) to bring the imaging unit ( 3 ) into the desired position for resolving the image on the imaging unit ( 3 ), such as the focal plane created by the eyepiece.

The platform ( 2 ) holding the imaging unit can move laterally with respect to the adapter component ( 4 ) in order to position the imaging unit along the optical axis of the system. The imaging unit ( 3 ), platform ( 2 ), and adapter component ( 4 ) can all be locked in a desired position. 
         [0027]    In one embodiment, the device is comprised of an adapter component ( 4 ) that further comprises a c-clamp component ( 4   a ) that can tighten onto an eyepiece of a microscope ( 3 ) with enough force to secure it in place and allow for the assembly to slide along the eyepiece ( 1 ). The adapter component ( 4 ) further comprises a dovetail component ( 4   b ) that may slide in relation to a platform with a mating dovetail element ( 2 ). A clip ( 5 ) can slide along the platform ( 2 ) to hold an imaging unit ( 3 ) in a desired position. In certain embodiments, clip ( 5 ) may have one or more angled features ( 5   a ). The c-clamp component ( 4   a ) can be tightened onto a cylindrical component on the microscope system to lock it in a desired position. The platform can be locked in place with respect to the c-clamp component with thumbscrews ( 6 ). The imaging unit ( 3 ) can be located and locked with respect to the platform ( 2 ) with one or more clips. In yet other embodiments, no locking mechanism is required and all components may be stable and immobile due to the resultant combination of gravity forces and friction between mating components. 
         [0028]    In some embodiments, the adapter component ( 4 ) further comprises a c-clamp that is split into two components. One c-clamp element ( 4   c ) may be affixed to the dovetail component ( 4   b ) of the adapter component ( 4 ). The second c-clamp element ( 4   d ) can be moved relative to the first element in order to accommodate large size differences in the cylindrical objects, which may be clamped. In some embodiments, the second c-clamp element may ride on two guide pins that may be affixed to the first c-clamp element. A screw ( 4   e ) may move the second c-clamp element. 
         [0029]    In some embodiments, the adapter component ( 4 ) comprises two components that move in relation to each other along the axis of cylindrical component on optical system ( 1 ). The platform ( 2 ) moves with respect to the adapter component. The platform ( 2 ) further comprises two or more components that can themselves move with respect to each other allowing for lateral translation. The platform ( 2 ) further comprises a clamp ( 9 ) to hold an imaging device. The platform and adapter components can be moved with one or more screw mechanisms. 
         [0030]    In some embodiments, translation of any or all of the adapter ( 4 ), platform ( 2 ), or clip components ( 5 ) is performed with screw mechanisms. 
         [0031]    In some embodiments, the clip ( 5 ) may have angled faces that orient and center a rectangular shaped imaging device. 
         [0032]    In some embodiments, the platform and/or clip positions can be adjusted with precision screws. 
         [0033]    In some embodiments, one or more clip can be used to hold the imaging device in the desired location on the platform and the clip can have guiding features to center and hold captive the imaging device against the platform.
