Maybe used either as a close-up stand microscope or long distance monocular telescope. When using this monocular as a telescope, objects can be observed at a minimum working distance of 300 mm. The close focus lens and acrylic base can simply be screwed onto the monocular resulting in an excellent stand or positioning microscope with field of view of either 9 mm or 7.2m depending upon whether the short version (KS) or long version (LS) is used (resulting in different magnification factors). This must be selected when ordering. A cutaway in the clear base allows access to touch the object under inspection. The base can be removed for irregular objects or when not required, for example when it is used as for positioning inside industrial equipment. The image is not reversed. Both lens systems (ocular and close focus lense) are achromatic and have an anti-reflection coating. Use of this monocular in combination with the close-up lens is not limited to technical applications. Due to the high light sensitivity, true image and magnification factor, it is also an excellent vision aid. Practical uses include a stand microscope, telescope, a reading aid or straight forward quality control. A high quality box with neck strap is included.
