Lenses
Lenses are used in optical systems with axial symmetry, transmitting, refracting, concentrating, or diverging a light beam. Popular materials for lenses are BK7, fused silica, sapphire. CaF2, MgF2 from UV to IR. Simple spherical lenses combined with other optical devices usually work very well in many demanding optical applications with relatively low cost. Our lenses are high-quality polished. High damage threshold coatings are available such as AR, HR, PR coatings.
