The invention discloses a glycosuria measurement device, comprising a prism body and a housing. The prism body comprises a first accommodating space, a junction surface, a first light penetrating surface, a second light penetrating surface, a third light penetrating surface and a light-emitting surface. The first accommodating space accommodates urine. The junction surface is formed at a bottom surface of the first accommodating space. The first light penetrating surface is formed at the first lateral surface of the first accommodating space. The second light penetrating surface is formed at the second lateral surface of the first accommodating space. The third light penetrating surface is disposed opposite to the junction surface. The light-emitting surface is disposed opposite to the junction surface. The housing comprises a second accommodating space, a first light-emitting port and a second light-emitting port. The second accommodating space accommodates the prism body.

This invention discloses a riflescope wherein the point of aim is adjusted by a pair of partially-rotating wedge prisms. The prisms are positioned in front of the objective lens of the riflescope. The deviation axes of the prisms are oriented perpendicular to each other such that one deviates the light beam in the horizontal direction and the other in the vertical direction. It is shown, using the geometric properties of a tangent to a circle, that rotating each prism by a small amount can produce an approximately linear shift in the point of aim of the riflescope. The riflescope introduced in this invention has no laterally-moving parts, no turrets and no off-axis optical components. Therefore, it provides a very robust and reliable point of aim. Additionally, the riflescope has a streamlined body which is aesthetically pleasing and easier to mount on the long receiver of magnum hunting rifles.
