A detector assembly for use with an analyzer instrument comprises a light source for providing a light beam for analyzing one or more substances in a sample. A detector is included for detecting light associated with the sample under analysis. An analysis station permits the light beam to enter the sample and shields the sample from extraneous light. The analysis station further permits light to pass from the sample to the light detector. A plurality of filters is selectively positionable in the light beam between the light source and the sample. These filters permit different wavelengths of light to pass therethrough so that selective light analysis of the sample may be performed.

A detector assembly suitable for use in an instrument for analyzing samples carried in a light transmissive carrier comprising: a light source for providing a light beam for use in analyzing one or more substances in a sample; a detector for detecting light associated with the sample under analysis; an analysis station into which a carrier for the sample to be analyzed is positionable and into which the light beam is to be directed, said analysis station including a body membrane with a central opening for receiving the carrier and for surrounding same to shield the sample from extraneous light and to maintain the position of the carrier during analysis, said station including a first aperture in communication with said central opening for permitting incident light from the beam to enter the carrier with the sample, and a second aperture in communication with said central opening for permitting light to pass from the sample to said detector so that the sample may be analyzed; a coating on said body member around the central opening to maximize the light shielding of the sample from extraneous light; and a rotatable filter wheel having a plurality of light filters spaced in a substantially circular arrangement in said wheel, each filter being interposable in the light beam between the light source and the analysis station, the filters permitting different wavelengths of light to pass therethrough so that selective light analysis of the sample may be performed depending upon the position of the wheel.
