Optical Engineering & Instrumentation

FUEL designs and manufactures optical systems for analytical scientific instruments. We develop imaging systems, spectrometers, and laser instruments for demanding applications: small-molecule detection, wastewater monitoring, critical mineral identification and quantification, and materials identification. Each one ships as a turnkey instrument, with the optics integrated with custom electronics, firmware, and enclosure. Whether we are pushing an existing instrument to a lower detection limit or developing a bespoke system from scratch, the optics are engineered alongside the electronics, mechanics, and firmware they depend on, all under one roof.

What we design

Optical systems

We design the complete optical path, from the layout and components through the illumination and the analysis that keeps stray light and tolerances in check.

• Optomechanical design and optical system, lens, and mirror design
• Illumination design and fiber optics
• Imaging systems, spectrometers, and laser systems
• Spectroscopy and analytical instruments: fluorescence, UV-Vis, and atomic emission
• Hyperspectral imaging for material and chemical mapping
• Coating selection, optical tolerancing, and stray-light analysis
• Optical alignment and assembly

Turnkey analytical instruments

We do not stop at the optics. We integrate the optical system with the electronics, firmware, and enclosure it needs to become a working instrument, and we push existing systems to new performance.

• Full integration of the optics with custom mechanical, electrical, and firmware design
• Redesign of existing systems for greater precision, lower detection limits, and reduced interference
• Bespoke instruments developed to your performance metrics and the right performance-to-cost balance
• Trace-level detection, including handheld instruments for small-molecule detection down to parts-per-billion
• Low-volume production of the finished instrument

Chemistry-informed measurement

The optics are only half of an analytical instrument; the chemistry of the sample is the other half. Our chemists and biochemists work alongside the optical and mechanical teams, so the measurement is designed around the real behavior of the samples and reagents.

• Optical and electrochemical measurement principles
• Sample and fluidic path design that preserves sample integrity
• Material compatibility and contamination control
• Sample-preparation workflows

Tools, standards & methods

We design the full optical path in-house: optomechanical layout, lens and mirror design, illumination, tolerancing, and stray-light analysis. The optics are co-designed with our mechanical, electrical, and firmware teams, so alignment, mounting, thermal behavior, and readout are engineered together rather than bolted on afterward. Every instrument is aligned, assembled, and functionally tested in-house before it ships, and measured against the detection limits, precision, and interference targets its application demands.

Optical work runs under the same quality system as the rest of our engineering: our devices are developed under a quality management system pursuing dual ISO 9001 / ISO 13485 certification, currently at the pre-audit stage, applied to every project.

Where it fits in our process

A specialist optics house hands back a lens prescription or an optical bench and leaves the integration to you. FUEL delivers the whole instrument: the optics designed together with the electronics, firmware, enclosure, and sample path, informed by in-house chemistry expertise, then aligned, assembled, functionally tested, and carried into low-volume production. You get a working analytical instrument, not just an optical design. See how we work for the full path from concept to production.
