Laser Module Usage Precautions

(Important – Buyers Must Read Before Use)

Operating laser modules involves potential optical and thermal hazards. To ensure safe and proper use, please read the following precautions carefully before powering on your laser product.

  • General Safety Warnings​

    • Invisible Radiation Warning– Some laser modules emit infrared (IR) or ultraviolet (UV) radiation that is invisible to the human eye. Never assume the laser is malfunctioning simply because you cannot see the beam. Always confirm that the power is disconnected before inspecting the module.
    • Do Not Look Directly into the Laser Aperture– Even when wearing certified laser safety goggles, never stare directly into or near the beam exit of a working laser module.
    • Avoid Reflected Beams from High-Power Lasers– Reflection from Class IV lasers (output power > 500 mW) can cause severe and permanent eye damage. Always wear wavelength-specific safety goggles when operating or aligning high-power laser systems.
    • Keep Away from Flammable Materials– Do not place flammable or explosive items (such as paper, cloth, leather, or plastics) in the laser path. Black or dark-colored materials absorb laser energy more easily and may ignite. (Exception: controlled material-burning experiments with proper fire protection.)
    • Avoid Direct Human Exposure– Class IIIa or higher lasers (≥ 5 mW) can burn skin or eyes. Never point a laser beam at any part of a person’s body.
    • Restrict Access to Trained Personnel Only – Keep all laser devices out of reach of untrained individuals, children, and pets.
  • Optical Path and Reflection Safety​

    • Never Aim Toward Glass Surfaces– Ordinary glass reflects roughly 4 % of incident light, which can redirect dangerous laser radiation into your eyes. Avoid operating lasers in front of mirrors or reflective windows.
    • Working Plane Awareness– When setting up an experimental platform, note the laser emission height. Do not position your head or eyes near this level during operation. Lenses and mirrors may reflect or refract light unexpectedly. Always align optical components downward or horizontally—never angle a beam upward.
    • Remove Reflective Accessories– Watches, jewelry, and other shiny objects can reflect laser light unpredictably. Remove them before use.
    • Infrared Beam Detection– IR lasers (wavelength > 800 nm) are almost completely invisible. Use a beam-viewing card, IR detector, or up-conversion screen to visualize the beam path safely.
    • Visual Brightness Misjudgment– Some wavelengths (below 430 nm or above 700 nm) appear much dimmer than their actual power output. Do not rely on visual brightness to judge beam intensity.
    • Pulsed Laser Caution– Pulsed lasers can have extremely high peak power even at modest average power levels. Verify that all optical elements and samples in your experiment exceed the laser’s damage threshold before exposure.
    • Prohibited Uses– It is strictly forbidden to point laser beams at moving vehicles, aircraft, or any area where light could distract or endanger others.
    • End-of-Beam Safety Stop– Always place a black anodized or matte metal plate at the end of your optical path to absorb residual energy and prevent laser leakage into surrounding areas.

    Low-Power Modules – ERDI laser modules rated below 1 mW are considered eye-safe under normal operating conditions and can be used without hazard when handled properly.

  • Recommended Protective Measures​

    • Protective Eyewear– Always wear certified laser safety goggles designed for the specific wavelength and power level of your module.
    • Appropriate Clothing– Light-colored or white long-sleeved clothing reduces the risk of heat absorption or ignition if stray laser light contacts the fabric.
    • UV Laser Protection– For ultraviolet lasers, apply broad-spectrum sunscreen (SPF 30 or higher) to exposed skin areas to minimize UV radiation effects.
    • Environmental Safety– Operate lasers in a controlled laboratory or industrial environment with minimal reflective surfaces. Ensure that all personnel nearby are informed of ongoing laser use and have received proper training.

The 1500m Semiconductor Pulse Rangefinder Module leverages 905nm TOF technology for precise 5–1500m distance measurement. Featuring UART (TTL_3.3V) interface, single-shot/continuous ranging, direct TTL-to-MCU connectivity, PC configuration software, and standardized command protocols.

Product Description

LRF1500A 905nm Eye-Safe 1500m Laser Rangefinder Module for Industrial Automation, Robotics and Outdoor Instruments

The LRF1500A is a compact 905nm Class 1 eye-safe laser rangefinder module that uses time-of-flight (TOF) technology to measure distances by calculating the round-trip travel time of laser pulses. With a measuring range of 5–1500 m and an integrated UART (TTL_3.3V) interface, it is designed as an OEM core for industrial automation, mobile robots, surveying tools, traffic and security systems, and outdoor measuring instruments that need a small, low-power distance sensor rather than a heavy long-range unit.

At a wavelength of 905±10 nm and classified as Class 1 under IEC 60825-1, the module achieves a typical laser divergence of 3×6 mrad and a receiver field of view of about 8 mrad, offering a good balance between spot size and capture field for building-type targets. Under visibility ≥6 km and 70% reflectivity building targets, the maximum range is ≥1500 m and the minimum range is 5 m. Ranging accuracy is specified as ±0.7 m for distances ≤200 m, and ±(0.7+0.0004·d) m for d>200 m, where d is the distance in meters, while the accuracy rate is ≥98% and the false alarm rate is ≤1%. This gives integrators a clear, quantitative basis for system error budgets and application design.

The measurement frequency is adjustable from 1 to 3 Hz, making the LRF1500A1 well suited to applications such as slow-moving mobile robots, pan/tilt heads, level and height gauges, and low-rate monitoring points. TOF operation with single-shot and continuous ranging commands lets the host system request readings on demand or stream data continuously when tracking motion, while keeping power consumption under control.

Electrically, the module is powered from DC 3.3±0.1 V. Standby power consumption is ≤0.5 mW when the enable pin is pulled low, and ≤0.35 W when powered but idle with the enable pin high. Operating power is ≤1.5 W @25°C, ≤1.75 W @70°C and ≤1.38 W @−20°C. Startup time is ≤550 ms, allowing the host to switch the module on only when needed and still obtain a reading quickly. These characteristics make the LRF1500A1 attractive for battery-powered instruments, compact industrial nodes and autonomous platforms that run on limited power budgets.

The electrical interface is a UART (TTL_3.3V) serial port using connector model HC-0.8-6PWT, with pins for GND, 3.3 V supply, TTL_TXD, TTL_RXD and an enable pin. The default baud rate is 115200 bps, but the module supports 9600, 19200, 38400 and 57600 bps as well, which can be set via simple commands. Communication uses an 8-byte frame beginning with headers 0x55 0xAA, followed by a function word, four data bytes and a checksum consisting of the low eight bits of the sum of the function word and data bytes. Single-ranging, continuous-ranging and stop commands (0x88, 0x89, 0x8E) all follow this protocol, and measurement results are returned as high and low bytes representing the distance multiplied by 10 for 0.1 m resolution.

The module also supports angular measurement (0x8A) when used in a host device equipped with an angle sensor, returning the angle data in the same scaled-hex format. A power-on self-test reply (0x80) provides STA and ErrCode information to distinguish boot failures, out-of-range conditions, no-echo situations and hardware errors, helping engineers perform diagnostics during development and in the field. External-circuit enable and disable commands (0x70 / 0x71) are provided to implement a secondary low-power mode, where the MCU remains in standby but can still respond to commands, so the host can wake the module simply by sending a measurement command.

Mechanically, the LRF1500A1 measures 26×25×14.5 mm (L×W×H) and weighs 11±0.5 g. It is qualified for 1200 g / 1 ms impact and 2.5 g vibration (5–50–5 Hz, 1 octave/min), with an MTBF of ≥1500 h. The operating temperature range is −20 to +70°C, storage temperature −25 to +75°C, and the module meets typical ESD, EMC (CE/FCC) and RoHS 2.0 requirements when integrated according to the guidelines. These characteristics support long-term use in outdoor instruments, traffic devices, compact robotic platforms and industrial sensors.

For systems that use an external optical window, the documentation recommends H-K9L optical glass with a high-quality surface (Ra ≈ 0.012) and wedge angle tolerance ≤3′. An anti-reflection coating optimised for 855–955 nm with transmittance ≥99.5% is suggested, and total transmittance after any hydrophobic or hard coatings should remain ≥98%. The window geometry should ensure that the effective aperture is at least 2 mm smaller than the window outer diameter, that the antenna clearance is ≥1.5 mm and that thickness is typically 2–4 mm, with the emission axis parallel to the window normal and an air gap as small as possible. These measures help maintain the specified measuring range and response speed.

The manual also analyses factors that affect ranging capability and response speed: target reflectivity, target shape, measurement angle and environmental conditions such as fog, rain, haze, sunlight and airborne particles. For example, targets with higher reflectivity—such as road signs—can be measured well beyond typical building ranges, while low-reflectivity targets like dark trees or animals reduce the maximum range; water surfaces and glass may be difficult or impossible to measure. For distant targets, the module should be mounted on a tripod to minimise shaking and ensure more stable results.

With its 905nm Class 1 eye safety, 5–1500 m range, TOF principle, compact 26×25×14.5 mm, 11 g design, 3.3 V supply, UART-TTL interface, low-power modes and flexible protocol, the LRF1500A1 is an excellent choice for industrial automation sensors, mobile robots, smart traffic and security devices, surveying instruments and outdoor measurement tools that require reliable mid-range distance data in a very small form factor.
