Double Sided Polishing
Supporting a large increase in demand for precision optical flats / etalons, Crystran has just taken delivery of another new state-of-the art double-sided polishing machine from Somos-Nanotec – their TPM400A. In addition to being a very efficient machine for the volume polishing of large batch sizes, a key advantage is in the unit’s inherent capability to deliver parts with faces highly parallel – within 5 arc seconds!
Given the wide range of materials we polish at Crystran (CaF2, MgF2, ZnSe, Ge, etc), process repeatability is always at the forefront of our minds. The TPM is fully temperature controlled, which is hugely important when it comes to optimising performance repeatability, as it enables our technicians to use a much wider range of polishing slurries / pads / pressures and speeds – all recipe driven at the push of a button.
