Glass and infrared materials supplier Naked Optics Corp. of Warren, N.J., announced last week it has signed a distribution agreement with Hubei New Huaguang Information Materials Co. (NHG) of Xiangfan, China. The glass inventory will be distributed from Naked Optics' New Jersey warehouse. NHG has been producing glass since 1969 and makes over 93 types. Its annual output of optical and specialty glasses is more than 15 million lbs. Naked Optics, which also distributes Pilkington Special Glass and Phoenix Optical Glass Ltd., said the NHG agreement comes after Pilkington announced last year that it will cease optical glass production.
