1535nm Eye-Safe Laser Rangefinder Module
Long Range Erbium Glass Laser Ranging Sensor
Introduction to 1535nm Eye-Safe Laser Rangefinder Module
A 1535nm eye-safe laser rangefinder module is a long range laser ranging sensor built around erbium glass laser technology. Unlike common 905nm laser diode ranging solutions, 1535nm infrared light falls into the eye-safe optical window. Even at higher peak power, this erbium glass laser ranging module greatly reduces the risk of eye injury for operators, which makes it the preferred solution for outdoor long-distance ranging applications.
Leirte’s 1535nm eye-safe laser rangefinder module integrates erbium glass laser emitter, optical receiving system, signal processing circuit and APD detector. The compact design supports easy embedding into optical systems, observation equipment, UAV payloads and industrial measuring devices. Our laser ranging module delivers stable long-range distance data under complex weather conditions including haze, fog and dust.
Core Advantages of Erbium Glass Laser for 1535nm Long Range Laser Ranging Sensor
Eye-Safe Wavelength Characteristic
The 1535nm band is recognized as an eye-safe infrared wavelength. When compared to 905nm laser diodes, the 1535nm erbium glass laser allows higher pulse energy without damaging human eyes. This feature is critical for outdoor field measurement and portable rangefinder equipment where personnel exposure may occur.
Better Atmospheric Transmission
The 1535nm erbium glass laser has lower atmospheric attenuation. In fog, smoke and light rain environments, this long range laser ranging sensor maintains more reliable detection performance than near-infrared 905nm ranging modules. It supports longer detection distance while keeping compact module size.
Stable Pulsed Output & Compact Integration
Erbium glass laser generates high peak power narrow pulse signals. The pulsed laser output helps the 1535nm eye-safe laser rangefinder module achieve high precision time-of-flight calculation. The module structure is optimized for embedded integration, suitable for portable device miniaturization. It also supports wide operating temperature range for outdoor and harsh industrial scenarios
