Defense & Homeland Security


Inrad Optics has served the needs of defense contractors, the military and government agencies since our founding in 1973. Our super-precision optics, optical assemblies, proprietary UV crystals and Q-switch crystals are used in a wide variety of military, homeland security and law enforcement applications, including:

  • Target range finding
  • Target designating
  • Target acquisition
  • Surveillance reconnaissance
  • Thermal imaging
  • Hyper spectral imaging
  • Missile warning systems

In addition to commercial-off-the-shelf (COTS) Pockels Cells and Q-switch crystals, we also offer build to print services. Our engineering teams in New Jersey and Florida also specialize in optimizing defense designs for manufacturability. Inrad Optics is DDTC registered and fully compliant with ITAR regulations.

Research & Development


Our long history of providing government and academic institutions with R&D products dates to the beginning of Inrad Optics in 1973. That tradition continues today, and we are are well-known supplier of the optical components and systems used by national laboratories, universities, and scientists around the world.

Our R&D expertise includes:

  • Specialty and proprietary crystal growth
  • Crystal component fabrication
  • Crystals and devices for second harmonic generation applications
  • X-ray optics for the world’s most sophisticated x-ray imaging facilities

Inrad Optics Products can be found in R and D applications in institutions worldwide. Our crystal and Autotracker products are widely used in UV and IR spectroscopy applications that employ the harmonics of tunable NIR lasers. Our x-ray monchromators are used for surface analysis via X-ray photoelectron spectroscopy as well as in plasma X-ray spectroscopy.


Semiconductor


Inrad Optics possesses a unique expertise in fabricating large form factor optics for semiconductor wafer inspection. Our super-precision large transmission flats and large format fold mirrors are utilized in dual-sided interferometers that deliver best-of-industry nanotopography and wafer edge roll-off metrology.

  • Large Transmission Flats. Routine specifications for the transmission flats include:
    • Flatness of λ/20 at 633 nm P-V or better
    • Irregularity of λ/20 at 633 nm P-V or better
    • Surface quality of 10:5 or better over 95% of the clear aperture
  • Large Format Mirrors. Our Metal Optics operation produces tight-tolerance reference mirrors used for laser interferometric wafer inspection systems. The large mirror pairs used in these interferometric tools exemplify Inrad Optics’ commitment to work with our customers to achieve very demanding surface and coating specifications that are both highly repeatable and measurable. Our large format mirrors for semiconductor applications offer:
    • Mirror faces to 26 inches Flatness to 0.125 waves via diamond turning
    • Perpendicular X-Y mirror faces to 20 arc-seconds
    • Reflective metallic coating for use with the NIR laser interferometer system

Other products for semiconductor applications include waveplates, polarizers and projection lenses.

Process Control & Metrology


Inrad Optics has developed expertise in meeting optical needs of the process control and metrology markets. As a key supplier to the companies focused on X-ray photoelectron spectroscopy (XPS), Inrad Optics’ deep materials expertise provides these companies with a knowledgeable partner for both OEM production as well as R & D projects.

XPS is a powerful technology that has been optimized to provide the automation, speed and reliability required in today's advanced semiconductor production environments. Uniquely suited for the move to thinner films and smaller features, XPS systems have been deployed for a wide variety of product and monitor wafers.

Our X-ray monochromator expertise builds on our scientific understanding of crystalline materials. We supplement that materials expertise with:

  • Proprietary optical contacting methods
  • Exacting metrology procedures
  • Stringent quality control techniques



Laser Systems


Inrad Optics Pockels Cells and Q-switch crystals are industry standards for medical, industrial and military laser systems. We run vertically integrated manufacturing operation in which all crystal growth, fabrication, orientation and assembly takes place in our own facilities. Our end-to-end control of crystal growth and fabrication results in unequaled traceability and quality control.

Our Pockels Cells and Q-Switch crystal have set the standard in a variety of applications:

  • Medical. Our high-extinction-rate BBO is the preferred material for ultrafast medical laser systems.
  • Defense. We are a longtime supplier to the defense prime contractors requiring high volume Q-switch crystals with performance guarantees. We offer custom designs specifically to meet the military
  • Industrial and Scientific. Laser manufacturers have chosen the Inrad Optics Pockels cells for demanding applications, including small form factor applications.  In addition to standard products, we also develop custom electro-optics tailored to the most challenging laser system requirements.
