Maximum Precision
Γ α incorporates material and component upgrades while maintaining basic proven structure of Γ II and Γ III.
Γ α S achieves repeatability of 0.1 µm (4σ).
Temperature characteristics are improved, accomplishing 0.08 μm/℃ 0.8 μm/10℃.
High-precision measurement is achieved, as Γα is resistant to temperature fluctuation experienced in a production environment.
High durability
Double sealing boots prevent damage and improve durability.
An enhanced fulcrum improves overall stiffness, giving reliable and accurate measuring.
Versatility
Γ α is highly versatile and can be used to replace existing gauges such as Γ II and Γ III.
Γ α has universal mounting features, meaning it can be used to replace other suppliers conventional models with no modifications to existing fixturing.
