    Abstract: A device for measuring the intensity of incoming light is disclosed. This device includes a rotatable light blocking unit which interrupts incident signal light at short regular intervals. The device also includes a light source which emits certain light different from the signal light while the signal light is interrupted by the block unit, and a measurement unit for measuring intensity values of the signal light and the certain light. A correction unit is provided for correcting the measured signal light intensity based on the certain light intensity. A calculator unit calculates a correction value through comparison of the intensity of the certain light to a reference value. The correction unit uses this correction value to correct the signal light intensity.

    Abstract: An optical transmittance apparatus has a pair of reference channels of glass rods and a pair of sample channels containing sample fluid. A beam splitter and mirror pass a first portion of an incident beam through an ingoing reference channel, and a second portion through an ingoing sample channel. The first portion is reflected back through an outgoing reference channel, and the second portion back through an outgoing sample channel. The beam splitter and mirror directs the outgoing beams into a common outlet path. A partial disk selectively passes either portion. For positioning the disk, poles of a magnet mounted on the disk axle face windings made about an axis perpendicular to the axle, the windings being on the opposite side of a barrier plate from the poles. Current of one polarity through the windings effects one orientation of the disk, and reversed olarity reorients it perpendicularly.
