Technical Specifications

Process Capabilities

  • Standard Footprints: Comprehensive coverage from TO-3, TO-5, TO-8, TO-18, TO-39, TO-46, to TO-52 configurations.
  • Optical Window Customization: Available in Single or Dual Window configurations with precise flat glass or integrated lenses.
  • Window Dimensions: Ranging from micro-apertures (Ø 1.0mm) to large custom rectangular windows (e.g., 5.0 x 3.8mm) for specialized optical paths.
  • Hermetic Sealing: Robust Glass-to-Metal Seal (GTMS) technology guaranteeing extreme pin-to-header hermeticity.
  • Material Selection: Standard Kovar and specialized alloys available, including custom 304 Stainless Steel builds for extreme corrosion resistance.
  • Plating & Finish: Full or selective Gold (Au) plating options (e.g., TO-8 Au-plated caps) for superior conductivity, oxidation resistance, and solderability.
