25X Microscopes and 8X Telescopes
Prism Monoculars: Telescopes
Keplerian Manual Monoculars
by Eschenbach Optik
25X Microscopes/8X Telescopes
These prism monoculars can be used in a variety of ways:
 | First, as a hand-held telescope 8X to detect details at a distance,
such as street names, house numbers, paintings in museums, etc. |
| Second, as a hand-held microscope 3X for closeup (short focus) viewing |
| Third, as a stand microscope of up to 25X for inspection of surfaces in
industrial applications, also useful for coin inspection, etc. |
Characteristics:
| High degree of transmission and image brilliance |
| Dust-protected light metal housing |
| Foldable eye cup |
| Precision focusing with adjustment ring

Note about lenses:
Biconvex lens: Distinguised by two spherical (convex) surfaces. Used
in large field, low power reading magnifiers. Magnification usually up to 4X.
Aspheric Lens: Aspheric curves allow higher magnification with less
distortion. Used by holding the more convex side (side with imprint) towards the eye.
Magnification up to 12X.
Aplanatic Lens: Consists of two equally strong plano-convex lenses. The
convex sides are arranged face-to-face. Full image is clearly defined and free of
distortion. Magnification up to 20X. (Magnification up to 4X useful for persons with
macular degeneration.)
Achromatic Lens: Top quality lens. A color-corrected lens system that
guarantees a clear, sharp image. Completely distortion free. Magnification up to 25X.
