• 1/10λ form measurement performance for aspheric optics

• 200mmØ x 12.5mm SAG capacity, which can be increased to 50mm with special styli
  
  
• Machine tool feedback for grinding, polishing and diamond turning process optimisation
  
  
• 0.8nm gauge resolution and 1nm RMS measurement noise delivers genuine optical surface finish measurement capability
  
  
• New Aspherics Analysis Software meets the needs of both production and research users
  

Form Talysurf PGI 1240 is the benchmark for the form measurement industry. Unprecendented 12.5mm gauge range with 0.8nm resolution provides simultaneous assessment of form, dimension and texture with a single traverse. Key features include system noise reduced to less than 1nm (RMS); 0.1um straightness over 200mm traverse; and X axis horizontal data spacing to 0.125um. The Form Talysurf PGI 1240 system also includes an environmental cabinet to reduce the effects of airborne vibration.

Calibration over a ball and full arcuate correction provide optimum measurement accuracy. The Form Talysurf PGI 1240 is designed with the flexibility to accomodate the workshop or laboratory user with manual or programmed operation capability.
