Predictika · Laser quotes: OBIS LX/LS

An AI sales agent's laser proposal, checked before it goes out

An AI sales agent proposes a Coherent OBIS LX or LS laser for a customer's instrument: the wavelength, the rated power option, the output the application needs, the modulation, the temperatures, the noise, and any power supply the customer brings. Before it goes out, the agent sends the proposal to Predictika, which checks it against a declarative model of the published datasheet and returns a verdict, every reason and the figures it computed.

Scope: Coherent OBIS LX and LS free-space lasers (30 models, 375 to 980 nm): power options, requested output, modulation, temperatures, noise and customer-supplied DC power. See everything this validator covers

This validator models proposals for one product line, the free-space OBIS LX and LS lasers, using the specification tables in the public Coherent OBIS LX/LS datasheets, not just the scenarios shown below.

  • Model and power option — 30 models by wavelength; the rated power options each model is offered with; the output the laser can actually be set to (up to 110 percent of rated power, and no lower than 1 mW or 1 percent of rated on an LX model).
  • Modulation — the digital and analog modulation limits of each model (for example 50 kHz digital and 100 kHz analog on LS models; up to 150 MHz digital and 500 kHz analog on most LX models).
  • Temperature and noise — the ambient operating range, the baseplate temperature limit and the RMS noise each model is specified at.
  • Customer-supplied power — 12 VDC plus or minus 2, more than 20 W, ripple under 5 percent and line regulation under 0.5 percent.
  • Stated figures — the wavelength and maximum output the agent states are compared with the datasheet on every call.

Any proposal for these lasers that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Coherent does not publish a price list, so there is no price build-up or line-item quote), the fiber-pigtail (FP) and single-frequency (SF) models, cables, remote and other accessories, beam quality and beam diameter, and application engineering such as optics, heat sinking design or safety classification.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Power options that differ for every modelOnly with care
Each of the 30 models is offered with its own list of rated powers (the 405 nm model has six, the 413 nm model has one); that is a table to load and keep in step with the datasheet, and a missed option lets an unoffered power into a quote.		The offered options are part of the model data and are checked on every call.
A maximum output that depends on the power optionOnly with workarounds
The laser can be set up to 110 percent of its rated power, so the ceiling is a function of the option chosen, and a request between rated and 110 percent needs a person to confirm; a flat per-model attribute cannot express both limits.		The ceiling is computed from the option, and the band between rated power and the ceiling is reported as an approval.
A lowest setting that depends on the seriesOnly with workarounds
LX models cannot be set below 1 percent of rated power (and nothing below 1 mW); LS models only have the 1 mW floor. The rule has to read the series and the option together.		The floor is computed from the model and option and compared with the requested output.
Limits that differ between LX and LSOnly with care
Modulation speeds, ambient range, baseplate limit and noise differ by series and by model; each is a separate lookup that has to be kept in step with the datasheet.		All limits are looked up from the model on every call and each is checked against its own limit.
Stated figures that disagree with the datasheetOnly with care
The wavelength and maximum output the agent states are free-entry fields; a rule can compare them with the datasheet, but only if someone writes and maintains it for every model and option.		The stated figures travel with the proposal and are compared with the computed ones on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the proposal is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent proposes a Coherent OBIS LX or LS laser for a customer's instrument: the wavelength, the rated power option, the output the application needs, and more. Before it goes out, the agent sends the proposal to Predictika, which checks it against a declarative model of the published datasheet and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Coherent OBIS 405 LX laser with the 300 mW rated power option. The application needs 300 mW at the output, with digital modulation at 20,000 kHz and analog modulation at 100 kHz. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The selected model is not offered with a rated output of 300 mW. The customer supply is rated 18 W; it must be more than 20 W. The customer supply has 6.0 percent peak-to-peak ripple; it must be below 5 percent.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for power options that differ for every model, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the rated power option to 365 mW, the customer supply power to 30 W, the customer supply ripple to 1 and the customer supply line regulation to 0.2. It sets the stated maximum output to 402 mW.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
