New Glass Types


We are pleased to introduce S-TIH53W which offers higher internal transmittance than our existing S-TIH53 glass. This new S-TIH53W glass has been developed to maintain the same basic composition and refractive indices (including Nd and Vd) of the original S-TIH53 glass, while providing the improved transmittance. This new glass will provide optical designers with an additional material to consider for future lens systems.
