plano-convex

The fiber is laser-fused directly to a plano-plano silica rod (endcap) or plano-convex silica lens, resulting in an index matched transition from fiber to lens without any glass to air interface to cause unwanted back-reflections.

Diagnosis: Basidiomata clitocyboid, pileus 13-30 mm diam., infundibuliform to plano-convex, white to pastel grey, lamellae decurrent, stipe cylindrical, with mycelial pad and rhizomorphs, basidiospores 4-5 x 3-4.3 [mu]m, globose to subglobose, smooth to slightly angled in polar view, cystidia absent, pileipellis a transition between trichocutis and a trichoderm, clamp connection absent.

They attach to a variety of microscope systems and feature designs made up of an achromatic doublet and a single plano-convex lens, where both convex surfaces face one another.

Introduced in 1880, it consists of a cemented triplet field lens paired with a single-element biconvex or plano-convex eye lens.

Pileus 30-55 mm diam., plano-convex, broadly umbonate, undulating surface, deep cinnamon to red-brown to dark brick, central disc darker, in mature specimens surface zonate, surface smooth, viscid, shiny, cap margin clearly white to cream with dentate processes, involute.

A fiber-optic probe (Emvision LLC) with one centered excitation fiber (200 [micro]m core) and seven surrounding collection fibers (300 [micro]m core) and a plano-convex lens that covers in front of the fibers limiting the working distance of the probe to be 0-400 [micro]m specified in the specification sheet.

RMI's laser beam expanders are made with high precision plano-concave and plano-convex lenses - available in a wide range of materials.

The 250-W luminaire features an enclosed 360-deg rotating barrel, a locking shutter and a heat-resistant Plano-Convex lens.
