ERDI TECH LTD · Chengdu, China
Laser rangefinder modules for sensing and measurement.
ERDI TECH LTD — USCC 91510100MA64PTJK1U — was founded on 7 May 2021 with RMB 10,000,000 registered capital and about 50 employees. The current catalog spans DToF sensors, OEM laser rangefinder modules and erbium-glass laser sources. Explore the full product catalog and check each product page for its wavelength, published conditions and available documentation.
Start with what you need to measure. Use each model’s specifications and available technical documents to check the fit, then discuss samples, pricing, and project details with Tommy Yu.
We are certified for R&D and sales, not for manufacturing.
Our ISO 9001:2015 certificate (no. 02825Q11586R0S, valid 19 May 2025 to 18 May 2028) names one scope: research and development of optoelectronic devices — solid-state lasers, semiconductor lasers, laser rangefinders — and their sale. A management-system certificate describes how a company works. It is not a product certification for any model, and it does not certify a factory. We are not going to describe it as one.
Five steps, all of them ours.
Assembly, optical alignment, calibration, functional verification and final acceptance are performed in-house. The quality chain runs materials and coatings → pulsed laser source → range measurement chain → electro-mechanical integration → final acceptance, and the release record for a unit carries its configuration ID, its functional sequence, its inspection result.
Not published: whether the housings are machined here or bought in. It is not recorded in any source we hold, and until it is, this page does not claim it.
Not published: whether every unit is functionally tested or a sample-based AQL is used. We will answer it for a named project rather than guess on a web page.
Licensed to export, selling direct.
The registered business scope includes import and export of goods, import and export of technology, and import-export agency, so orders ship from Chengdu under our own license. There is no distributor, reseller or agent for ERDILRF anywhere.
Not published: the countries we have shipped to so far. We will answer it for a named project rather than guess on a web page.
Wavelength
Why we focus on 905 nm.
905 nm remains our lead rangefinder family, alongside 1535 nm rangefinders and erbium-glass laser sources in the wider catalog. The LRF10VB record specifies 940 nm. Wavelength alone does not establish price or suitability. Compare the exact product, configuration and published measurement conditions; request a quotation where no reference unit price is listed. Browse all product families or discuss your application and available documentation with ERDILRF.
What 905 nm buys the integrator is mass and power. SPD1200N0 measures 0.2–1,200 m (1,500 m at night) to ±0.3 m below 100 m from a Ø15.7 × 21.3 mm cylinder weighing about 5 g, on 3.3–5 V and an average 0.45 W. LRF3000A1 reaches at least 3,000 m against a 70%-reflectivity building target in clear air at 12 ± 0.5 g. Those two numbers — grams and watts — are the ones a gimbal, a monocular or an airframe actually has to absorb.
Disclosure
What we publish, and what we refuse to.
Model pages carry the available specifications and any published reference unit price. Models without a published price require a quotation. Read each specification with its published measurement conditions. Where a field is genuinely unknown to us it reads “on request” or “not published”, and we do not fill it from a sibling model. SPD1200D03’s datasheet contradicts itself on the default baud rate — the protocol section says 115200 bps, the technical table in the same document says 15200 bps — and we publish the conflict rather than pick the answer, because a host configured against the wrong one fails in your field, not on our bench.

The document applies to the tested sample and configuration only. It is an EMC test declaration for the models listed, not blanket CE certification of every product in the current catalog. Ask for the test report when you need it for a specific model.
Copies of both documents and the EMC test report are available on request for the model you are evaluating. Request documents
