I explain how to select and use your parts, with worked examples and figures drawn from code. Your specialist provides the product data, joins an interview and reviews the draft.
If your team answers the same design question every week, that answer belongs in a document an engineer can find before they call. For example:
“Can this TEC hold my set-point at a 50 °C case, and what does that do to wavelength?”
“How far does this filter’s passband move at 10 degrees in an f/2 cone?”
Line chart. Chip temperature change (K) from −0.5 to 0.5. Fabry-Perot: −119.0 to 119.0; DFB, high coefficient: −50.0 to 50.0; DFB, low coefficient: −31.0 to 31.0 (Wavelength shift (pm)).
Support teams get this question every week. Set the beam’s wavelength, waist and M², then drag the lens along the axis: the spot radius at your work distance updates as it moves, along with the new waist, the Rayleigh range and the divergence on each side of the lens.

Spot radius at the work distance w(d)
118µm
M² = 1, same waist: 90.5 µm

Spot radius 118 µm at 120 mm after a 100 mm lens placed 300 mm from the waist; new waist 112 µm, 128 mm after the lens.
Each is quoted with a fixed scope and price.
From the free review, or from the list your sales team already has.
About an hour with your specialist, plus your datasheets and test data.
I write the document and prepare its figures from your data.
One technical review, then one final review of the revisions. Technical articles include one review round.
The final document, figures and calculation files.
Yes. I can ghostwrite for your engineer, and they review and sign off before anything is published.
About an hour for the interview, followed by a technical review of the draft. Application notes and white papers also include a final review of the revisions. Technical articles include one review round.
Your datasheets, any test data behind the example, and the question with who asks it. Public-release information only.
Yes, on request: a MATLAB script as an add-on. By default the calculation files are written in Python and delivered with the note.
The proposal sets out ownership and usage rights for the document, figures and calculation files.
Launching a new part? The Product Launch Package pairs a technical article with a datasheet refresh, a product page, three posts and the launch email.
