What LetinAR does
LetinAR Co., Ltd. (주식회사 레티널) is a privately-held South Korean AR optics company founded in October 2016 by CEO Jae-hyeok Kim and CTO Jeong-hun Ha, headquartered in Dongan-gu, Anyang-si, Gyeonggi-do. The company develops proprietary optical architectures — PinMR™ (basic patent August 2018) and PinTILT™ (basic patent December 2020) — for augmented reality and AI smart glasses. PinTILT™ is a geometric angular-remapping architecture that combines waveguide efficiency with birdbath image quality, delivering what the company describes as all-day wearability, all-in-one manufacturability, and all-around compatibility with OLEDoS, microLED, LCOS, and LCD microdisplays. The firm holds 80+ registered patents as of December 2023 and is recognized as a Korean National Strategic Technology (March 2025).
LetinAR's commercial product line consists of three optical modules sold B2B to smart-glasses OEMs: the Letinus™ ultra-thin everyday-AI module (25° FOV, 6 g monocular, 3.5 mm thickness, paired with Sony µOLED); the FrontiAR™ Brighter high-performance module (36° FOV, 1,000 nit luminance); and the FrontiAR™ Wider wide-FOV module (45° FOV). The modules are produced at the company's in-house Fab in Anyang (established March 2021), where injection-molded plastic lens manufacturing was validated by the B30 PinTILT™ plastic lens mass production milestone in May 2023. LetinAR distributes exclusively through direct enterprise sales — quote-based ordering via a B2B inquiry form on the website and the [email protected] inbox — with no public price list, no resellers, and no marketplace presence.
The customer base to date spans Japan (NTT QONOQ Devices for MiRZA® Smartglasses launched October 2024; Dynabook for the B42C in mass production April 2025), Switzerland (Aegis Rider for AR motorcycle helmets, EU/Swiss launch targeted 2026), and first sales recorded to North America (February 2022) and Europe (March 2022). The company also pursues industrial/specialty wearables (Aegis Rider), automotive HUDs, and government R&D partnerships with Korean ministries (MOTIE, MSS, MSIT). LetinAR has raised ~$41.7 million cumulatively across five funding rounds (Seed 2017 through $18.5M pre-IPO in May 2026 led by Korea Development Bank), with LG Electronics and Lotte Ventures among prior investors, and is preparing for a 2027 South Korea IPO.

LetinAR product offering
Product offeringCore offering
LetinAR designs, manufactures, and sells proprietary optical modules for augmented reality (AR) and AI smart glasses. Its product family is built on two patented architectures — PinTILT™ and PinMR™ — and includes the Letinus™ lens module (ultra-thin everyday-AI module), the FrontiAR™ Brighter module (professional/high-fidelity), and the FrontiAR™ Wider module (wide-FOV). Modules are sold quote-based B2B to smart-glasses, HUD, and AR-goggle OEMs globally.
Product overview
LetinAR is a single-company platform built around two proprietary core optical technologies, PinTILT™ and PinMR™, which together form the foundation of the company's optical-module product family for AR and AI smart glasses. On top of this optical platform, LetinAR ships three named lens-module products: the Letinus™ Lens Module (the ultra-thin "Module for Everyday AI" using Sony µOLED at 25° FOV), the FrontiAR™ Brighter Lens Module (professional/high-fidelity 40°+ FOV variant), and the FrontiAR™ Wider Lens Module (45° FOV variant in two design types). PinTILT™ and PinMR™ are not just R&D efforts but are offered both as integrated lens modules and as licensable architectures (with whitepapers, evaluation kits, and B2B ordering), making the offering a technology-and-modules platform rather than a single product. Customer-facing modules have shipped to NTT QONOQ Devices, Dynabook, and Aegis Rider, and the company continues to scale ahead of its planned 2027 IPO.

LetinAR competitors and assessment
Company assessmentDirect peers
- Dispelix: Dispelix develops single-layer and dual-layer diffractive waveguide displays for AR glasses — the principal competing architecture to LetinAR's PinTILT™. Both companies sell B2B optical modules to AR-smart-glasses OEMs and are pursuing the everyday-eyewear form factor.
- Lumus: Lumus manufactures reflective waveguide optical engines for AR headsets and smart glasses. Like LetinAR, it supplies OEMs (defense, medical, consumer) and positions its technology as a path to slim, mass-producible AR eyewear.
- DigiLens: DigiLens produces surface relief grating (SRG) waveguides for AR/MR devices used in enterprise and automotive HUD. It competes with LetinAR for OEM design wins in AR-display optics, with particular overlap in the auto-HUD and industrial-wearable segments.
- Vuzix: Vuzix is a US-listed maker of AR smart glasses and waveguides. It both manufactures finished AR eyewear (overlapping with LetinAR's Letinus™/FrontiAR™ modules in end-applications) and supplies waveguides to OEMs, making it a direct competitor in the B2B AR-optics value chain.
- WaveOptics (Snap Inc.): WaveOptics, acquired by Snap, supplies diffractive waveguide optical modules for AR smart glasses. It is one of the most direct competing licensable waveguide platforms to PinTILT™, and Snap's ownership positions it as a vertically-integrated platform competitor.
- Magic Leap: Magic Leap develops AR headsets and associated optical engines. It competes with LetinAR for enterprise/industrial AR-eyewear design wins and shares the same target OEMs for AR-display optics.
Emerging players
- Optinvent: Optinvent designs AR optical engines (ORA / ORA-X) for enterprise and industrial smart glasses. It is a smaller European specialist with a comparable B2B optical-module offering, overlapping with LetinAR in industrial-wearable use cases.
Broad incumbents
- Microsoft (HoloLens / Mixed Reality): Microsoft's HoloLens program is a vertically-integrated incumbent in AR optics, with in-house waveguide and combiner development. It does not sell modules to third parties, but competes for the same enterprise AR customer wallet and could in-source what it cannot buy.
- Apple (Vision Pro): Apple is the broadest AR/VR incumbent and a benchmark for high-fidelity AR optics (Vision Pro). It does not license modules but defines the consumer AR-eyewear standard against which PinTILT™-enabled products are measured, and is a potential long-term partner/acquirer in the AI-glasses category.
Others
- Sony (Semiconductor Solutions — µOLED): Sony is both a key supplier (µOLED microdisplay used in Letinus™) and an adjacent AR-ecosystem player with its own spatial reality displays. It is a critical enabler/partner for LetinAR's product line and a potential vertical competitor as AR-glasses demand scales.
