The American Biology Teacher, 1971

Professional performance, well within the range of tightened school budgets, is what makes Swift ... more Professional performance, well within the range of tightened school budgets, is what makes Swift Stereo 80 an odds-on favorite with the science teaching fraternity. The entire concept of Swift Stereo 80 design-from optical system to mechanical features-resulted from a survey of the needs and wants of the finest school laboratories in the country. Every desired feature was scientifically engineered into the instrument to provide maximum capabilities at minimal price. Swift Stereo 80 gives you the widest choice of magnifying powers available, ranging from lOx to 120x. Objectives bring you the widest, flattest field of viewing-from 8.8 to 17.5 mm, depending on magnification. Highest quality prisms (NOT mirrors) are separately clamp-mounted (NOT cemented) to their shelves. Achromatic, widefield eyepieces are coated to increase light transmission; locked in to prevent tampering, but are removable for cleaning; designed to accept eyepiece measuring scales, and have diopter adjustment on right eyetube. Write or call today for literature describing the unique tri-illumination, advanced mechanical design, and various accessories, plus name of your nearby Swift dealer for a demonstration.
