Introducing a new optical glass type: S-LAH99W, an improved transmittance version of S-LAH99


We are pleased to announce the release of a new optical glass type named S-LAH99W, which has improved internal transmittance in the 360 – 550 nm range while maintaining the high refractive index (Nd 2.001), low specific gravity and excellent polishing characteristics of S-LAH99. This new industry-leading, high index, glass provides an exciting new choice for optical designers and is very well suited for use in applications such Augmented Reality waveguides and other devices.
