WebSpherical Lenses Thanks to modern manufacturing technologies, we are able to produce spherical lenses of high quality and from different materials. In addition to optical glasses, these include crystals such as germanium and silicon, metals, PMMA and IR materials. Web30 Oct 2014 · Eyepiece Prices. In general, you pay more to get 1) better sharpness, not just at the center of the field, but also out to the very edge and 2) wider apparent fields of view. Telescope eyepieces that excel at both use complex lens systems of the highest quality and these do not come cheap.
