A Huddersfield company will be welcoming a member of the Royal family to its premises.
Chemical firm James Robinson Ltd will officially receive the Queen's Award for Innovation from HRH the Duke of Kent on Friday, November 10.
It is the first time that royalty has visited the firm, which is based in Hillhouse Lane and was founded in 1840.
Brendan Catlow, managing director of James Robinson Ltd said: "It is a huge day for the company and we are really proud to have been recognised in this way."
The company won the award for developing patented special dyes for opthalmic lenses. The new dyes react to changes in light levels and are mainly used in spectacle lenses which are transparent in poor light, but get darker as the light brightens.
During his visit the Duke will be given a demonstration of the innovative products, a tour of the firm's laboratories, where he will meet some of its scientists, and unveil a plaque in the canteen area to mark his visit.
He will also make the official presentation of the award.
The Mayor and Mayoress of Kirklees, Clr Donald and Mrs Ann Firth, will also attend.
The Duke will be the second royal visitor to Huddersfield in the space of just a couple of weeks.
Last Friday Sophie, the Countess of Wessex, visited Holly Bank School, Mirfield, to officially open a £1.5m centre providing therapies to profoundly disabled children and adults.
