It includes both the Prism (see above) and Super Prism lenses. The Super Prism lens is a superior quality, three-element color-corrected lens, ideal for photographs that require fine detail reproduction. It has better accuracy than the Prism lens, and a horizontal projection range of 3X to 20X. 230 mm, f/4.5 lens. Weighs 9 lbs (4 kg). Super Prism Lens — Add the superior quality Super Prism lens, described above, to upgrade any Prism art projector to the Super Prism art projector. The lens gives you finer detail and increased image clarity, even when images are enlarged 20X. The Prism — This projector is specially designed for projecting a wide assortment of originals, such as patterns, sketches, and line drawings. Includes the standard Prism lens. The horizontal projection range allows for enlargement up to 20X and reduction down to 80% (of the original size), by simply reversing the lens. 225 mm f/4.8 lens. Weighs 8 lbs (3.6 kg). 250W Photo Bulb — Two 250W photo bulbs are included with the projector. The advantage of using an ordinary 250W bulb in a projector is its longer bulb life. However, the 250W photo bulb is recommended because it gives a much truer reproduction of color. Lasts approximately 25 hours.
