We offer our customers plano-convex curved windows. Curved windows consist of two substrate materials covering a range of thermal expansion coefficients. For applications where thermal shock is not present and thermal stability is not critical, BK7 glass is a suitable material. For applications requiring high thermal stability or involving severe thermal shock, UV grade fused silica is a good choice.
