Large Optics Application Examples

Certain applications necessitate the use of large optical elements such as mirrors, beam splitters, optical flats, windows, lenses, or diffraction gratings.

  • Optical Elements for Large Telescope Use: For telescopic applications, optical elements play a crucial role in gathering and directing space-derived light to scientific instruments. Major components of the Optical Telescope Element (OTE) per NASA include primary mirrors, secondary mirrors, tertiary mirrors, Thermal Management Subsystem, Aft Deployable ISIM Radiator, Wavefront sensing and control, among others. 
  • Large Optics for Ultrashort Pulse Compressors: Large optics play a critical role in safely compressing ultrashort pulses with high peak power. Their expansive beam cross-sections prevent intense peaks that can damage equipment or cause breakdowns. Efforts are concentrated on streamlining setups to reduce costs and space requirements, achieved through utilizing high-quality optical surfaces with durable coatings to resist light damage. Precision polishing and advanced coating methods such as magnetron or ion beam sputtering are essential. Following fabrication, rigorous tests are conducted to measure the laser-induced damage threshold (LIDT).
  • Large Optical Elements for Imaging Use: High-resolution optical imaging demands very large optical elements for two key reasons. Firstly, diffraction limits achievable angular resolution. A larger input aperture allows capture of finer details, crucial for resolving faint objects. Secondly, a larger aperture gathers more light, enabling shorter exposure times for imaging faint celestial bodies. This minimizes the impact of noise that degrades image quality. Additionally, these systems require extremely high-precision optical surfaces to minimize aberrations and ensure optimal light transmission, ultimately delivering superior image fidelity.
  • Optical Metrology: For large optical elements with stringent specifications, high-precision optical metrology becomes crucial yet challenging. Precise characterization of these optical elements and systems is vital for their optimal performance.
