Abstract

An improved near-infrared quantitative analysis instrument is disclosed comprising a removable finger insert which facilitates properly aligning and fitting and individual user's finger into the optical system of the analysis instrument. The finger insert according to the present invention also prevents the analysis instrument's optical system from being damaged by foreign matter typically introduced by a user's finger. The finger insert can also be provided with filters which will enable the insert to be used as an optical standard for the analysis instrument.
