A sample vessel for holding a sample for analysis by a sample analyzer, the sample vessel comprising: a body that includes a bottom , an open top spaced from the bottom along a first axis , a side wall that extends from the open top to the bottom , and an interior chamber for holding a sample and that extends from the open top toward the bottom along the first axis , the body including an opaque portion , a first translucent portion , and a second translucent portion spaced from the first translucent portion a distance that extends along a second axis that is perpendicular to the first axis and that forms an optical axis (Z), the first and second translucent portions each disposed along the bottom of the body , wherein the body includes an opaque body component that defines the opaque portion , a first translucent component that defines the first translucent portion and a second translucent component that defines the second translucent portion , wherein the sample vessel is an injection molded part with multiple components that define the opaque portion and translucent portions , wherein the opaque component comprises a first polymeric material, and the first and second translucent components and each comprise a second polymeric material that is different from the first polymeric material, wherein the second polymeric material is selected from the group consisting of a cyclic olefin copolymer, acrylic, acrylic copolymer, polystyrene, polycarbonate, polyetheramide, and other translucent polymeric materials, and copolymers thereof, and wherein the sample vessel includes a predominant amount of the opaque portion relative to the first and second translucent portions . a body that includes a bottom , an open top spaced from the bottom along a first axis , a side wall that extends from the open top to the bottom , and an interior chamber for holding a sample and that extends from the open top toward the bottom along the first axis , the body including an opaque portion , a first translucent portion , and a second translucent portion spaced from the first translucent portion a distance that extends along a second axis that is perpendicular to the first axis and that forms an optical axis (Z), the first and second translucent portions each disposed along the bottom of the body , wherein the body includes an opaque body component that defines the opaque portion , a first translucent component that defines the first translucent portion and a second translucent component that defines the second translucent portion , wherein the sample vessel is an injection molded part with multiple components that define the opaque portion and translucent portions , wherein the opaque component comprises a first polymeric material, and the first and second translucent components and each comprise a second polymeric material that is different from the first polymeric material, wherein the second polymeric material is selected from the group consisting of a cyclic olefin copolymer, acrylic, acrylic copolymer, polystyrene, polycarbonate, polyetheramide, and other translucent polymeric materials, and copolymers thereof, and wherein the sample vessel includes a predominant amount of the opaque portion relative to the first and second translucent portions . <EOS>
