Ereo

What Ereo does

EREO (SAS EREO) is a French private company founded in 1993 and headquartered in Chauny (Aisne), specializing in the design and small-series manufacture of custom opto-electronic systems. The firm integrates optics, electronics, and mechanics under one roof to deliver bespoke instruments — ranging from laser pointers for surgical microscopes, dermatology and ophthalmology laser treatment equipment, and slit-lamp filters, to optical benches (RainbowSlab, Sheetscan), biological counting benches, and process-monitoring microscopes. Its two flagship branded products are Crystavision, a real-time video microscope for sugar crystallization control, and TéléTact, a light-beam distance-to-music sensor for visually impaired users developed with ANVAR support and distributed via AVH Paris.

The company operates a project-based business model: customers submit a cahier des charges, EREO studies alternative approaches, builds a prototype using its in-house optics lab, electronics lab, mechanics workshop, and assembly room, and then transitions to small-batch manufacturing upon validation. Revenue streams are predominantly one-time hardware sales of custom systems and small series, supplemented by sales of specialized branded equipment. Pricing is quote-based and not publicly disclosed; contract cadences are described as multi-year for project engagements.

Go-to-market is sales-led and relies on direct contact (website contact form, phone, callback request), supplemented by referral relationships with industrial laser partners, university scientific partners (notably Institut de Génie Énergétique de Belfort), and a single distribution partnership with AVH Paris for the TéléTact accessibility line. The team consists of approximately three people (electronics engineer, optical engineer, assembly operator), placing EREO firmly in the micro-enterprise category with no external investors, no subsidiaries, and no disclosed M&A activity.

Core offering

Ereo designs and manufactures custom opto-electronic systems, taking customer specifications through prototype development to small-series production. The company produces specialized laser equipment for medical applications (ophthalmology, dermatology, surgical microscopy), process monitoring instruments such as the Crystavision cooking microscope for sugar crystallization, optical measurement benches, and accessibility devices like the Télétact. Its capabilities span instrumental optics, electronics, and mechanical assembly in-house at its Chauny facility.

Product overview

EREO is a French company specializing in custom optical and electronic systems, operating as a design-and-manufacturing firm rather than a product platform. The company offers a portfolio of branded products including the Crystavision Microscope de Cuite (process monitoring microscope for sugar industry crystallization), the Télétact (distance-to-music conversion device for visually impaired users), and specialized laser treatment equipment for dermatology and ophthalmology. Supporting products include the RainbowSlab and Sheetscan optical bench systems, pointof-care laser pointers for surgical microscopes, biological analysis counting benches, and custom measurement/experimentation benches. The company also provides end-to-end prototype development and small-series manufacturing services. Most products are custom-built to customer specifications rather than off-the-shelf offerings.
