OEM/ODM Custom Development for Laser Modules
Most integrators do not need a new laser. They need an existing laser with a different mounting face, a different connector, a different message set, or a different label. OEM/ODM work is usually about the interface around the laser, not the laser itself.
This page sets out what is realistically customisable, what is not, and how a development programme runs.
What is customisable
| Area | Customisation | Effort |
|---|---|---|
| Mechanical | Mounting datum, hole pattern, bracket, envelope adjustments | Low–medium |
| Connector | Type, pinout, harness length, strain relief | Low |
| Interface | Message set, framing, protocol adaptation, CAN IDs | Medium (firmware) |
| Firmware behaviour | Self-test sequence, power-on state, error semantics, rate limits | Medium |
| Optical | Window coating, aperture window geometry, filter bandwidth | Medium |
| Thermal | Base-plate geometry, conduction path, cold plate interface | Medium |
| Branding | Label, silkscreen, packaging, documentation | Low |
| Environmental | Extended temperature range, additional sealing, conformal coat variants | High (requalification) |
What is not customisable
Being clear about this saves months:
- Wavelength. A 1064 nm module is 1064 nm. Changing it means a different laser medium and an entirely different product.
- Pulse energy beyond the platform's design. Energy is set by cavity size and pump; it is a new design, not a configuration.
- Divergence beyond the transmit optics. Optics can be refocused within a narrow band, but a large divergence change is a new optical design.
- Duty cycle beyond the thermal design. The qualified cycle reflects what the cooling can sustain. Extending it is a thermal redesign and requalification.
- Accuracy beyond the timing chain. The time-to-digital converter sets the floor.
If a requirement lands in this list, the conversation shifts from customisation to development, with a corresponding change in schedule and cost.
Development stages
| Stage | Output | Typical duration |
|---|---|---|
| 1. Requirements | Written specification: envelope, mass, interface, environment, quantity | 2–4 weeks |
| 2. Feasibility | Confirmation of what is configurable versus new design; NRE estimate | 2–4 weeks |
| 3. Prototype | 1–3 units to the agreed specification | 8–16 weeks |
| 4. Verification | Test report against the specification | 4–8 weeks |
| 5. Qualification | Environmental testing to the agreed standard | 6–12 weeks |
| 6. Production | Serial units with configuration control | Per schedule |
Durations depend on how much is genuinely new. A connector and label change is a few weeks; a new envelope with requalification is a year.
What to prepare before the first engineering call
- Envelope constraints — the space the module must fit, with connector volume included
- Mass budget — installed mass, not just module mass
- Power available — voltage, average and peak current
- Interface preference — RS-422 or CAN, and the host's framing
- Environmental profile — vibration, shock, temperature, humidity, salt fog
- Duty cycle — expressed as on-time, interval and repeats at a stated ambient
- Quantity and schedule — prototype count, annual volume, delivery dates
- Documentation requirements — datasheet level, test reports, export classification
Suppliers that ask for all eight are the ones that can quote accurately. Suppliers that quote from a one-line email are guessing.
Documentation and configuration control
For a programme that runs for years, configuration control matters more than the first unit. Ask for:
- a controlled datasheet with parameter definitions (full-angle vs half-angle divergence, accuracy convention)
- a revision history and a process for notifying changes
- a serial-number traceability scheme
- the interface specification as a controlled document
Without these, a module that worked in year one may be silently different in year three.
Frequently asked questions
Can you change the wavelength?
Not within a module family. 1064 nm is set by the gain medium; a different wavelength is a different product line.
What is a typical minimum order quantity?
This is commercial and depends on how much is customised. A label change has a low barrier; a new envelope with requalification needs volume to justify the NRE. Ask early, because it determines whether a custom path is viable for a prototype programme.
Who owns the custom design?
This is negotiated per programme. Clarify IP ownership, tooling ownership and whether the custom configuration can be sold to others, before development starts.
Can existing modules be rebranded?
Yes — labelling and documentation are the lowest-effort customisation, and a common starting point.
How do I know if my requirement is customisation or development?
If it is on the configurable list, it is customisation. If it changes wavelength, energy, divergence, duty cycle or accuracy floor, it is development.
