Opto-Alignment: Lens Alignment & Optical Metrology

Opto-Alignment: Lens Alignment & Optical Metrology

Opto-Alignment Technology, Inc. is a US manufacturer of ultra-precision lens alignment, optical metrology, and optics cleanliness solutions. The company has more than 30 years of experience and holds ISO 9001 certification. It designs, builds, and supports every system at its facility in Indian Trail, North Carolina. Optics manufacturers worldwide use its instruments to assemble, inspect, and protect lenses and optical assemblies working from the visible to the long-wave infrared (VIS–LWIR).

Active Lens Alignment – LAS™ Lens Alignment System
The flagship LAS™ is an automated active-alignment and lens-centering station for cemented and air-spaced lens assemblies. A traditional autocollimator only reports centering error. The LAS™ instead uses a focused laser in reflection to locate each surface’s center of curvature. Machine vision and automation then drive every element into position and verify 200 nm centration and 0.5 arcsec tilt before bonding.

  • Models: LAS-BT™ (benchtop), LAS-P™, LAS-UP™ and LAS-XUP™
  • Capacity: apertures up to ⌀900 mm
  • CalcuLens™ software adds:
    • Radius of curvature (ROC) measurement to 0.05%
    • Vertex and air-gap distance measurement
    • Beam deviation analysis
    • Multi-lens 3D inspection
    • Aspheric surface profiling
  • Accessory modules: VRM, ATM, IAM, RAM and DMI

3D Surface Metrology – QuickPRO™
QuickPRO™ combines chromatic confocal and interferometric sensors on one platform. It is a non-contact system for 3D surface topography, form, and thin-film or dual-sided thickness measurement of optics, wafers, and PCBs. It delivers sub-micron accuracy, with scans in under two minutes, at less than a quarter of the price of comparable systems.

  • Models: QuickPRO-3D™, QuickPRO-CUBE™ and QuickPRO-OCT™ (optical coherence tomography)
  • Applications include:
    • Aspheric and diffractive lenses
    • Micro-lens arrays and in-tray micro-lens inspection
    • Off-axis aspheric mirrors
    • Transparent films and patterned photoresist
    • LCD color filters and PCB substrates

Optics Cleanliness & Handling – Opto-Wipes™
Opto-Alignment also supplies the cleanroom consumables it uses in its own production:

  • Opto-Wipes™ lint-free, optics-grade lens-cleaning wipes
  • Lens Handler™ and ROTOwand™ vacuum lens-handling stations
  • Vacuum wands and Delrin® vacuum cups from 1 to 100 mm

These products help optics shops reduce contamination, scrap, and handling damage.

Engineering Expertise You Can Talk To

The company is led by President & CEO Guy Pearlman, who represents its second generation of leadership. Engineering is led by VP Jordan Hall, who holds multiple patents in metrology and lens design. Customer relationships are managed by Chris DePriest, Vice President of Business Development, who brings more than 20 years of optical-industry experience. Chris works directly with Opto-Alignment’s engineering and manufacturing teams to match each customer with the right alignment, metrology, or cleanliness solution. In addition to its products, the company offers opto-mechanical design, ultra-precision machining, and custom system manufacturing.

To get pricing, open any product listing and request the price. Chris will follow up personally, usually within one business day, with pricing and a recommended configuration for your aperture, element count, and tolerances.
