What HartSCI does
Hart Scientific Consulting International LLC (HartSCI) is a Tucson, Arizona-based designer and manufacturer of commercial adaptive optics (AO) systems, founded in 2008 by Dr. Michael Hart, an Associate Professor Emeritus of the University of Arizona College of Optical Sciences. The company sells the ClearStar™ product family — ClearStar AO, AO+, HP, and TT for meter-class astronomical telescopes, and ClearStar LC for ground-to-space laser communications — unified by the proprietary FasTRAC® software platform that automates wavefront sensing, deformable mirror correction, and tracking. HartSCI also supplies laser guide star systems, passive aircraft detection for laser safety, and complete optical ground station design packages.
The company generates revenue primarily through custom-configured capital equipment sales to government and aerospace customers (AFRL, AFWERX/Starfire Optical Range), ground-to-space laser communication integrators (TeraNet-2, Western Australia), and astronomical observatories via its strategic partnership with PlaneWave Instruments, which bundles ClearStar AO as a pre-integrated accessory with PlaneWave RC700, CDK700, and PW1000 telescopes. Pricing is quote-based on capital equipment sales, supplemented by custom engineering services and non-dilutive government R&D funding (notably a $1.25M AFRL MECSEL sodium guide beacon contract in partnership with the University of New Mexico).
HartSCI employs 1–10 people and has expanded its Tucson facility twice in 17 months (June 2024 and September 2025) to over 7,200 sq. ft. to support a growing order book. Its customer base skews toward U.S. government/defense and aerospace buyers, with international reach into Australia and standards-setting influence through the MOSA Interface Standards Alliance. The company is founder/management-owned, with no disclosed institutional equity rounds; growth has been funded through government contracts and operating cash flow.

HartSCI product offering
Product offeringCore offering
HartSCI designs, manufactures, and sells commercial off-the-shelf adaptive optics (AO) systems under the ClearStar brand, including laser-communication AO (ClearStar LC), general-purpose AO (ClearStar AO / AO+), high-performance AO (ClearStar HP), and tip-tilt correctors (ClearStar TT), all unified by its proprietary FasTRAC control software. The company's systems combine Shack-Hartmann wavefront sensors and deformable mirrors to deliver diffraction-limited astronomical imaging and atmospheric correction, with applications spanning ground-based astronomy, free-space laser communication, and government/defense space domain awareness. HartSCI also delivers custom engineering services, telescope integration, and complete optical ground station design packages.
Product overview
HartSCI offers the ClearStar family of adaptive optics products for telescopes used in astronomy, aerospace, and space-based asset tracking. The product line includes three main product categories: ClearStar LC (laser communications AO system), ClearStar AO/AO+/HP (adaptive optics systems for imaging), and ClearStar TT (tip-tilt correction). All products are powered by the FasTRAC© unified software platform. The systems correct atmospheric turbulence distortions in real-time using Shack-Hartmann wavefront sensors and deformable mirrors, enabling diffraction-limited imaging and enhanced signal coupling for laser communications. HartSCI also provides complementary technologies including laser guide stars, passive aircraft detection, and custom engineering services, plus complete Optical Ground Station design packages.
