Lens Elements

Janos technology is a leader in single point diamond machining technology.  We offer precision refractive and reflective optics manufactured with CNC two-axis single point diamond machining equipment. Janos caters to diverse industries such as aerospace, defense, medical devices, semiconductor manufacturing, and scientific research, where high-quality optical components are essential for various applications.

Surface roughness ranging from 5-100 Å RMS is quite common in precision optics manufacturing using single point diamond machining equipment. The actual surface roughness achieved can vary based on factors such as the material being machined, the specific configuration of the optical component, and the machining parameters used.

Maintaining consistent and controlled surface roughness is crucial for ensuring optical components meet performance specifications and minimize undesirable optical effects such as scattering or aberrations. Therefore, manufacturers typically employ rigorous quality control measures and inspection techniques to verify surface quality throughout the manufacturing process.
