Prepare before you send
Get to confirmation faster on the first contact
The more complete the information, the easier it is to judge material, pattern, and delivery in one pass; if the details are not ready, you can also discuss the product direction by phone first.
- 01
State the intended use first
Describe the equipment or station, the test/calibration task, working distance, and field of view; you can describe the problem even before a pattern is decided.
- 02
Attach a drawing or reference sample
Provide PDF, DXF, DWG, AI, CDR, PNG, or JPG files, and note the units, version, and any areas to preserve.
- 03
Add delivery conditions
Where possible, state the quantity, material/surface, mounting method, target lead time, and delivery location so engineering and pricing can be assessed together.
Request a quote
Start with a drawing or requirement
Send the drawing, product direction, and any special requirements; projects that pricing rules cannot cover are reviewed manually by an engineer.
