Official price range, published by ERDI TECH LTD: single-point 905/940 nm sensors from $6–$20 USD, 905 nm rangefinder modules from $30–$150 USD, and 1535 nm modules from $300–$3,500 USD at volume ($500–$7,000 USD for one piece). Every price includes worldwide shipping and the minimum order is one piece. The per-model tables below are generated from the same catalog as the product pages.
ERDI publishes the unit price of all 47 laser rangefinder modules. A single near-infrared module (905 nm, or 940 nm for the 9 m LRF10VB) costs from $10 to $400 (LRF1500H, 1,500 m range); a 1535 nm module costs from $500 (LRF0105C, 3 km class) to $7,000 (LRF1829C, 18 km class). Prices are in USD and include shipping, they are the same in every country, and each model has its own quantity ladder starting at one piece. Last updated 2026-11-13.
Single-unit price is the first band of each ladder. The last band is the best published price, usually from 500 or 1,000 pieces. Both come from the catalog the model pages are built from, so any row can be checked on its own page. If you already know the range you need, the selector filters by range, wavelength and interface.

All 47 modules by range and wavelength
Near-infrared modules up to 100 m (905 nm; LRF10VB is 940 nm)
The VB series weighs 1 to 1.5 g and the H series about 15 to 20 g. These are the parts for obstacle sensing, level triggers and indoor robots.

What is included in the price, and how to pay
- Shipping is included for every order, samples too. Import duty and taxes depend on the destination and are confirmed in the written quotation.
- There is no minimum order. The first band of every ladder starts at one piece, and an evaluation unit is a normal single-piece order at that price.
- Payment at checkout is PayPal (balance or card) or USD bank transfer. Bank details are shown after the order is placed and sent by email, and a proforma invoice follows.
- Lead time and warranty are confirmed in your quote. We do not publish a figure that the factory has not committed to in writing.
- Where the factory documents for a model disagree with each other, the model page says so instead of picking one value.
Market reference: published prices from other suppliers
These are prices other suppliers show on their own public pages, collected on 2026-11-13. We matched each one to the ERDI model with the closest stated range. Specifications, test conditions, interfaces and what is in the box differ between suppliers, so treat the pairing as a starting point and check both datasheets. Competitor prices exclude taxes where the source says so and may have changed since the date shown.

How to compare two quotes
- Check the target behind the range figure: size, reflectivity and visibility. A 1,200 m figure on a white building is not a 1,200 m figure on a dark panel.
- Check the minimum range. Modules in the 4 m class and in the 0.05 m class serve different jobs.
- Check the interface and logic level, and whether the frame format and checksum are documented.
- Check what the price includes: module only, cable, housing, test report, freight, tax.

Frequently asked questions
How much does a laser rangefinder module cost?
At ERDI a laser rangefinder module costs $10 to $7,000 for one piece, depending on range. A 905 nm module for 1 to 2 km is $80 to $120, and a 1535 nm module for 3 km or more starts at $500. Prices are in USD with shipping included.
How much is a 1 km, 2 km or 3 km laser rangefinder module?
A 1 km module (LR1000E2) is $80 for 1 to 30 pieces and $30 from 501 pieces. A 2 km module (LR2000E2) is $120 and $50 on the same bands. For 3 km, LRF3000A1 on 905 nm is $200 for 1 to 30 pieces, and LRF0305C on 1535 nm is $500 for 1 to 19 pieces.
Does the price include shipping and tax?
Shipping is included for every order, including a single sample. Import duty and taxes depend on your country and are confirmed in the written quotation. Payment is by PayPal or USD bank transfer, as shown at checkout.
Is there a minimum order quantity?
No. The first price band of every model starts at one piece, and an evaluation unit is an ordinary single-piece order at that price. Volume terms for larger orders are confirmed in writing.
Why is a 1535 nm module so much more expensive than a 905 nm module?
They are built from different parts and tested to different range targets. Compare the stated condition first: LRF3000A1 reaches 3,000 m on a 70% building target and costs $200, while LRF0305C lists 4,000 m at 60% reflectivity and costs $500. For 6 km and above only the 1535 nm line applies, from $1,000.
