What are the advantages of SF11 dove prisms?
High refractive index → more compact optical path design.
High dispersion → chromatic aberration compensation or multi-wavelength system optimization.
Mechanical stability → suitable for industrial environments.
High performance in the visible wavelength → Ideal choice for laser processing and precision instruments.
