Laser rangefinder suppliers — the four things to demand in writing
Board-level modules · published single-unit prices · figures verified 2026-10-23
A supplier claim worth trusting names the test target, the blind zone, the interface frame and the eye-safety class. Anything quoting only a maximum range against an unnamed target is a marketing number.
Four questions that separate suppliers
- Against what target size was the maximum range measured?
- What is the blind zone, and what happens inside it?
- Is the UART frame documented, with checksum and error codes?
- Which eye-safety class, and is it a module or system claim?

What this page does not claim
It does not quote competitors' specifications from memory, and it publishes no number our catalogue does not carry. Where a figure matters and is unpublished, ask for the datasheet.
Frequently asked questions
The same answers are published below as visible text and as FAQPage structured data, so the page and the markup cannot drift apart.
- Do you publish prices?
- Yes — the published single-unit price for every class is on the price ladder page, dated 2026-10-23. Volume tiers sit below these numbers and are quoted per order.
- Against what target is the maximum range measured?
- Long-range figures are stated against a 2.3 × 2.3 m reference target at the stated reflectance and visibility; short-range classes are stated against a 90% whiteboard. Compare the test condition, not the headline metre count.
- What interface do the modules use?
- UART-TTL with a documented frame and checksum on every published class. There is no native analog or 4–20 mA output; RS-485 needs a host-side transceiver.
