ELECTROGRIP SPECIAL OPTICS CAPABILITIES

• Laser machining:
  • Undetectable cutting damage in all optical materials
  • Crystalline sapphire, quartz, low-expansion glass ceramics, glasses etc.
  • NASA has used this capability for large mirror fiducial generation
• Diamond tool machining:
  • Low-expansion glass ceramics, quartz, glasses, ceramics are cut without detectable edge damage as determined by phase-shifting interferometry
  • NASA has used this capability for large mirror segmenting
• Large optics generation:
  • Up to 2m diameter optics can be generated with convex, concave, meniscus shapes under CNC control
  • NASA has used this capability for large ellipsoidal meniscus mirror generation
• Other machining -- use us with confidence when breakage is not an option:
  • Lightweighting and cutting of fine patterns, ultra-delicate machining of thin sections
• FEA simulations:
  • Assurance that designs will meet specifications through models and simulation prior to cutting
• Measurement of flatness, curvature:
  • Phase-shifting interferometry accurate to approx. 20nm over up to 200mm FOV, and to approx. 50nm up to 1000mm FOV
