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.

lenses (detailed specification as per annexure attached)
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
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.
Manufactured with dimensional tolerances ranging from [+ or -] 0.001" to [+ or -] 0.005", depending upon configuration, Laser Research ZnSe and ZnS Optics can be supplied as plano-convex
, plano-concave, and as wedged-windows in round, rectangle, and square shapes that can include steps, holes, and other special design features.
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.
