WDI designs

What WDI designs does

WDI designs, engineers and manufactures OEM microscopy automation solutions, founded in 2005 in Richmond Hill, Ontario, Canada and operated as a private, family-owned business with 51-100 employees. The company's core offering is its Precision Focus Automation (PFA) technology platform, which centers on laser-based through-the-lens (TTL) autofocus sensors (PFA-LN, PFA-DT, ATF4, ATF6, ATF6.5) using laser triangulation and structured light (dot and line patterns) with Advanced Multi-Stage Processing for high-speed focus tracking up to 8 kHz. Around this sensor core, WDI sells a modular ecosystem of integrated microscope systems (PFA-LN MMS, SWIR MMS, LFOV), IR laser confocal imaging systems (IRLC, LSCM), motorized Z-axis stages, linear lens changers, LED illuminators (high-power, fast-pulse strobe, SWIR), and dedicated motion/illumination controllers, all designed to be combined by OEM customers.

WDI serves OEMs and system integrators in semiconductor inspection, flat panel display manufacturing, genomics/life sciences, and machine vision/metrology, with named end-customers including Intel, Apple, Samsung, Corning, and LG, and OEM partners such as Excelitas Technologies (Optem FUSION platform), Zaber Technologies (Nucleus platform), Mitutoyo (VMU integration), and Dover Motion (DOF-5 stage integration). The business model is primarily direct enterprise/component sales through three regional sales managers (Americas/Europe, Asia ex-China/Taiwan, China/Taiwan), supplemented by seven authorized dealers/distributors in Israel, Taiwan, China, Malaysia, South Korea, and Japan. Pricing is quote-based with multi-year contract cadence; no public pricing is disclosed and revenue figures are not published.

The company has averaged over 15% year-over-year revenue growth for the past ten years, is celebrating 20 years of operation in 2025, and has continued product cadence with the January 2025 PFA-LN launch, the September 2024 RGB Fast Pulse LED illuminator, and the December 2023 PFA-DT. Leadership transitioned from founder Dr. Adam Weiss (PhD Physics) to his daughter Halszka Weiss as President, with the founder retaining a Founder title. No external funding rounds, M&A, or institutional investors are disclosed, and the company has no subsidiaries.
