BRASS-2000 is widely used for quality control in the contact lens industry.

When turning, it is not necessary to remove the machined material from the positioning rod, as it can measure the parameters of the semi-finished product (such as curvature radius, surface quality, etc.).

In the molding process, it can measure the concave or convex parameters of metal mold cores and plastic molds, providing a basis for the quality of subsequent molded products.

When turning, for a -5.00D contact lens, a 5u error means a 0.03D error!

Brass2000 helps you control similar errors.

Brass can measure semi-finished products or molds of corneal contact lenses

• Base bend

• forward bending
