The TB3078 series covers nD 1.41 to 1.59, and it is also possible to minutely control the refractive index to the desired value. To control the refractive index, the chemical composition of the UV-curing resin is changed. The UV-curing resin consists of various molecules, each having a unique refractive index. danish design cat beds uk https://boatshields.com
