Illuminating light of selected wavelengths in the visible or infrared range is projected through the pupil of the eye onto the fundus, and the light reflected back and out through the pupil is detected and analyzed, preferably using the area of the optic disk for analyzing the retinal vessels overlying the optic disk. Specific wavelengths of illuminating light may be chosen for each blood component to be analyzed depending on the spectral characteristics of the substance being analyzed. The reflected image from the retina may be used to measure non-photoreactive blood components such as hemoglobin, and photoreactive components such as bilirubin. For the measurement of photoreactive components, images may be taken before and after, or during, illumination of the eye with light at wavelengths which will affect the photoreactive analyte, enabling measurements of the concentration of the analyte.

An ink printer cartridge having a press-on lid and the method of make the same is described. An ink reservoir body is having an open-ended cavity and a foam insert is disposed therein. A spacer having a plurality of holes is fixedly attached to the top of the ink reservoir body as by ultrasonic welding. The reservoir is then filled with ink through the plurality of holes in the spacer. A reservoir lid having a plurality of connecting posts is then attached to the spacer by engaging the connecting posts of the lid into the holes of the spacer.
