     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The present invention seeks to provide an assembly toy including modular optical elements which can be combined and arranged to enable construction of a variety of optical devices. Preferably, in accordance with a preferred embodiment of the present invention, the assembly toy is of the interlocking block type, sold under the trademark Lego R or the trademark Superblocks R. 
     Reference is now made to FIGS. 1A and 1B which illustrate a simple, hand-held, pocket microscope, constructed and operative in accordance with a preferred embodiment of the invention. It can be seen that a modular lens element 10, typically comprising a lens portion 12, fixedly mounted in or integrally formed with a frame 14, which is formed to have an interlocking block configuration, is employed both at the top and the bottom of the hand held microscope. Normally the focal lengths of the two modular lens elements 10 employed in the pocket microscope are different. 
     An aperture defining element 16 is defined at a location intermediate a hollow column 18, formed by interlocking conventional elongate interlocking blocks 20, as seen in FIG. 1B. 
     Reference is now made to FIG. 2, which illustrates a microscope 30 formed of interlocking blocks of the type employed in FIGS. 1A and 1B. Here a modular lens element 10 is mounted on the top of a hollow column 32 of conventional elongate interlocking blocks 20 to define the ocular. Another modular lens element 10 is mounted on the bottom of column 32 to define the objective lens. Normally, the focal lengths of the two lens elements 10 are different. 
     Column 32 is supported on a stack 34 of interlocking blocks 36, which also interlock with blocks 20 to integrally join the stack 34 with column 32. Mounted onto stack 34 is a stage 38 for supporting a specimen to be examined. The stage 38 may incorporate a small aperture defining element 40, as illustrated. It is appreciated that the stage may be selectably positioned with respect to the objection lens. 
     Stack 34 is typically supported on a base 42, typically formed of a short stack of large interlocking building blocks 44. Preferably supported on base 42, in optical communication with stage 38 and aperture defining element 40 is an angled mirror element 45. 
     Reference is now made to FIGS. 3A and 3B, which illustrate an elbow, selectable focus telescope constructed and operative in accordance with a preferred embodiment of the present invention. A modular lens element 48 is provided at the end of a telescope tube 50 formed by a hollow interlocking stack of conventional elongate interlocking building blocks 20. 
     Slidably disposed within telescope tube 50 is an ocular tube 52, typically formed of a hollow interlocking stack of conventional elongate interlocking building blocks 54, which are shorter than blocks 20, so as to enable tube 52 to slide within tube 50. At the end of tube 52 facing the objective lens, there is provided a small aperture defining element 56. At the opposite end of tube 52 there is provided an angled mirror element 58 and an ocular lens defined by a modular lens element 10. 
     Reference is now made to FIGS. 4A-4G, which illustrate a collection of modular optical elements which can readily be combined with existing interlocking blocks to enable construction of optical devices as illustrated in FIGS. 1A-3B. FIG. 4A illustrates a relatively small lens element, such as lens element 10 described above having a first focal length. FIG. 4B illustrates another lens element, similar to element 10 but having a second focal length which is different from the first focal length. 
     FIGS. 4C and 4D illustrate two different sizes of aperture defining elements. FIG. 4E illustrates a relatively large lens element, such as element 48 described above. FIGS. 4F and 4G illustrate two configurations of angled mirrors, the embodiment of FIG. 4F, including a reflecting outer surface 60 and the embodiment of FIG. 4G including a reflecting inner surface 62. 
     It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. The devices illustrated and the optical elements described are for purposes of illustration only and it is appreciated that various other modular optical elements may be employed in connection with any suitable assembly toy, which may have various other moving or movable parts which have not been described herein.
