Actually, that is rather a bargain price. Achromatic lenses are corrected to two colors, apochromatic lenses are corrected to three colors and are much more expensive. Throw in IR and you'll need something like a "super-apochromatic" design corrected to even more points on the spectrum. That means more elements, stranger types of glass, etc... - and a ton more money! Throw in UV and your only customer might be Bill Gates.
