JML Optical Industries

What JML Optical Industries does

JML Optical Industries, now operating as Thorlabs Lens Systems (TLS) following its January 2023 acquisition by Thorlabs, is a US-based designer and manufacturer of custom precision optical components and assemblies. Founded in 1972 in Rochester, NY — the historic US optical and imaging hub — the company operates from a 70,000 sq ft vertically integrated facility employing 90+ engineers and technicians, of whom approximately 99% hold advanced optical or mechanical engineering degrees. Its product portfolio centers on four in-house glass fabrication capabilities (spherical/plano, aspherical, cylindrical, and acylindrical lenses) and includes optical assemblies, thin-film coating services (including the 2023 TLS1 plasma-source IAD chamber), design engineering, and the QuickTurn Optics rapid-prototyping program. Supporting infrastructure includes a Class 1000 cleanroom with Class 100 laminar flow workstations, a nitrogen chamber for complex assembly, and automated MTF testing capability.

The company serves OEM instrument developers across seven end markets, with defense and aerospace, medical devices, semiconductor equipment, and life sciences flagged as primary verticals, and industrial, imaging, and entertainment as secondary. It is ITAR registered, ISO 9001:2015 certified, and RoHS compliant, enabling participation in export-controlled defense programs and FDA-regulated medical devices. Customer evidence includes sole-source supplier status with a major defense contractor, volume production for an FDA-regulated medical device OEM (where yield rose from 50% to 99% after TLS engineering intervention), and long-running programs for aerial imaging (Pictometry/EagleView) and biometrics customers.

JML/TLS operates a B2B custom-manufacturing business model: revenue is generated per-project through direct enterprise sales relationships, with quote-based pricing, no public price list, and no distribution through resellers or marketplaces. Lead generation is driven by technical content (eBooks, tech notes, blog, case studies), tradeshow presence, and organic social channels, with conversion via Request a Quote and Contact Us CTAs. The company was previously backed by Five Points Capital (acquired 2011) before the Thorlabs transaction; the 2023 acquisition now positions it as Thorlabs' custom optical element and assembly manufacturing arm with access to global distribution.

Core offering

JML Optical Industries is a designer and manufacturer of custom precision optical components and optomechanical systems for OEM instrument developers. The offering spans aspherical, spherical, cylindrical, and plano lenses; in-house thin-film coatings (dielectric reflective, anti-reflective, bandpass, and mirror); complex lens assemblies built in cleanroom environments; optical and optomechanical design engineering using standard photonics design tools; and the QuickTurn Optics rapid prototyping service for faster prototype-to-production workflows.

Product overview

Thorlabs Lens Systems (formerly JML Optical Industries) is a precision optical solution provider offering a unified one-stop manufacturing platform spanning optical and opto-mechanical design, rapid prototyping, glass and metal fabrication, thin-film coating, metrology, environmental testing, and full assembly. The product portfolio centers on four primary glass fabrication capabilities (cylindrical, aspherical, spherical, and plano/flat lenses) which are offered both as individual precision optical components and as integrated optical assemblies. Supporting services include Design Engineering, QuickTurn Optics rapid prototyping, and Optical Coating services. The company operates vertically integrated manufacturing cells enabling prototype-to-production workflows for defense, medical, semiconductor, industrial, life sciences, imaging, and entertainment markets.

Products and services

• Custom Optics Design & Manufacturing End-to-end precision optical solution offering optical and opto-mechanical design, rapid prototype, glass and metal fabrication, thin-film coating, metrology, environmental testing, and full assembly under one roof for OEM instrument developers.
• Aspherical Lenses Non-spherical rotationally symmetric lenses with gradually changing curvature from center to edge, offering greater functionality than spherical lenses by reducing or eliminating spherical aberration, distortion, and marginal astigmatism.
• Optical Coating Services In-house thin-film coating including dielectric coatings (reflective, anti-reflective, bandpass filters) and mirror coatings (broadband, partial mirrors/beamsplitters), utilizing advanced vacuum chamber technology with plasma sources for the IAD process.
• Cylindrical Lenses Lenses with different radii in x and y axes that focus light into a one-dimensional line instead of a point, available in singlets, doublets, triplets, plano-convex/concave, sphero-cylindrical, symmetric convex/concave, and acylinder configurations.
• Design Engineering Services Optical and optomechanical design engineering services taking projects from initial concept to prototype to end product, optimizing for size, weight, manufacturability, ruggedness, and optical performance using AutoCAD, Code V, Inventor, SolidWorks, and Zemax.
• Optical Assemblies Complex lens assembly design, build, and testing services including imaging objectives, tube lenses, laser optic assemblies, doublet and triplet assemblies, viewing prism systems, fast aperture lenses, athermal lens systems, and focus/zoom designs.
• QuickTurn Optics Rapid prototyping service for custom optical components and assemblies delivering products in as little as 1 week for components and 4 weeks for assemblies, featuring dedicated manufacturing cells, state-of-the-art equipment, and vertical integration.
• Spherical / Plano Lenses Wide range of spherical lenses with constant radius of curvature (plano-convex, plano-concave, bi-convex, bi-concave, meniscus) and plano/flat optical elements for diverse imaging applications.
