Standard catalog parts don’t always fit a specialized instrument. Opto Diode — a division of ITW with more than 40 years of photonics manufacturing in Camarillo, California — designs and builds custom photodiodes, infrared detectors, LEDs, and IR emitters to a customer’s exact requirements, all with in-house wafer fabrication. This is an overview of what can be tailored; for a deeper look at building complete detection channels, see the guide on custom photodiode and LED assemblies.
What Opto Diode can customize
| Product family | What can be tailored | Typical use |
|---|---|---|
| Photodiodes | Active area, spectral response, and packaging | Precision light and radiation sensing |
| Infrared detectors | Element size, cooling, windows and filters | Gas analysis and environmental monitoring |
| LEDs & IR emitters | Wavelength, output power, and beam angle | Medical diagnostics through industrial automation |
Because both detectors and emitters are made in-house, they can be specified together as a matched pair rather than sourced separately. To choose a starting point, use the photodetector selection guide.
Industries we serve
- Aerospace & defense — reliable components for mission-critical systems
- Medical diagnostics — imaging and diagnostic equipment
- Environmental monitoring — precise detection of gases and pollutants

Quality and compliance
Opto Diode manufactures to rigorous standards, including ISO 9001:2015 certification and ITAR registration. On-site wafer fabrication, cleanroom facilities, and extensive assembly capability keep the full process under one roof in the USA — the control that custom, low-volume, and long-lifecycle programs depend on.
Frequently Asked Questions
What can Opto Diode customize?
Active area, spectral response, and packaging on photodiodes; element size, cooling, windows, and filters on IR detectors; and wavelength, output power, and beam angle on LEDs and IR emitters — plus custom optical assemblies that combine them.
Which industries does Opto Diode serve?
Aerospace and defense, medical diagnostics, environmental monitoring, industrial automation, and scientific research — anywhere a standard component can’t meet the requirement.
Is Opto Diode ISO and ITAR compliant?
Yes. Opto Diode is ISO 9001:2015 certified and ITAR registered, with US-based on-site wafer fabrication and cleanroom manufacturing.
