Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All present-day salamander families are grouped together under the scientific name Urodela. Salamander diversity is most abundant in the Northern Hemisphere and most species are found in the Holarcticecozone, with some species present in the Neotropicalzone.

The wood frog (Lithobates sylvaticus or Rana sylvatica[2]) has a broad distribution over North America, extending from the Boreal forest of Canada and Alaska to the southern Appalachians, with several notable disjunct populations including lowland eastern North Carolina. The wood frog has garnered attention by biologists over the last century because of its freeze tolerance, relatively great degree of terrestrialism (for a ranid), interesting habitat associations (peat bogs, vernal pools, uplands), and relatively long-range movements. The ecology and conservation of the wood frog has attracted research attention in recent years because they are often considered “obligate” breeders in ephemeral wetlands (sometimes called “vernal pools”) that are themselves more imperiled than the species that breed in them. The wood frog has been proposed to be the official state amphibian of New York.[3]

The Plethodontidae, or lungless salamanders, are a family of salamanders. Most species are native to the Western Hemisphere, from British Columbia to Brazil, although a few species are found in Sardinia, Europe south of the Alps, and South Korea. In terms of number of species, they are by far the largest group of salamanders.

Adapter designed to adapt the Mitutoyo LWD objectives to a lens with 77mm adapter. Includes (2) micro diffusers with small and large apertures/lens shades.
Large aperture is for objectives <50x, small aperture is for objectives >50x.
On a microscope or on a photographic system, like the Macropod PRO 3D, this diffuser set (3 in total) yield phenomenal results. They are custom designed for the Mitutoyo M Plan APO Objectives and can combine the properties of reflected and transmitted illumination. Using focus staking techniques, the lens shades stop light from entering the objectives glass while the white surface reflects diffuse light onto the sample. When observing microscope slides, the diffusers can reflect transmitted light back onto opaque materials such as gold and iron inclusions found in geological thin sections.
The diffuser with the smallest aperture with shade is for the 50-100x range, the diffuser with a large aperture with shade is for the 7.5-20x range and the diffuser with a large aperture and no shade is for the 1x-5x range. The shade is a Lieberkuhn reflector designed to stop light from entering the objective at the source. The white reflective surface is designed to softly illuminate the sample. These diffusers work exceptionally well for the Mitutoyo range.
