Using lead-free glass with a different reflection index and transition point, Alps has created lenses that are equivalent to existing products in terms of shape, specifications and price.

Alps Electric has developed a novel range of lead-free aspherical glass lenses for optical communications, including fibre to the home (FTTH) and submarine cable applications Quartz (silicon dioxide) is an extremely hard mineral and difficult to process compared with other raw materials used in glass

During processing, lead is usually mixed in to soften the material.

Using lead-free glass with a different reflection index and transition point, Alps has created lenses that are equivalent to existing products in terms of shape, specifications and price.

The new lenses can be installed in conventional facilities without modifying specifications.

Alps plans to propose to assembly manufacturers that they replace existing aspherical glass lenses with the new lead-free type.

Lead-free glass tends to have a lower reflection index compared with lead glass.

Therefore, in order to achieve the same optical properties as existing products, Alps has used optical design technology to redesign the shape of the aspherical surface to realise a higher refractive value.
