Products overview
1535nm eye safe Erbium glass laser module 500uJ 10Hz independently developed by Xinalnd, which features 500uJ high pulse energy and stable 10Hz low-frequency output, achieves narrow pulse width and low thermal damage processing by virtue of the erbium glass medium's superior energy storage capability, and is suitable for deep micromachining of hard and brittle materials like glass and ceramics as well as medium-to-high precision industrial and laboratory scenarios such as scientific research experiments.
Why 1535nm Stands Out as the Go‑To Eye‑Safe Laser Wavelength
1535nm has become the mainstream wavelength choice for eye‑safe laser rangefinders and remote sensing hardware. It strikes a real‑world balance: lower retinal injury risk, solid atmospheric propagation performance, and good compatibility with small‑form‑factor pulsed laser sources. All these advantages make it highly practical for field‑deployed optical systems.
Lower Retinal Risk With 1535nm Lasers
Unlike visible‑band light and shorter near‑infrared wavelengths, 1535nm laser energy gets heavily absorbed by the cornea and intraocular fluid before it can reach the human retina. This key optical property is why the 1.5 μm waveband is heavily adopted for outdoor eye‑safe laser rangefinders and field optical sensing equipment.
Even so, true laser safety cannot rely on wavelength alone. Real‑world safety performance is tied to pulse energy, beam divergence, output aperture, actual exposure scenarios, and corresponding laser safety class ratings.
Great Atmospheric Performance for Laser Ranging Work
The 1535nm waveband delivers favorable atmospheric transmittance for free‑space optical tasks, which makes it perfectly fit for laser distance measurement, LiDAR and time‑of‑flight ranging applications.
When paired with short‑pulse working mode, 1535nm erbium glass lasers generate robust time‑of‑flight return signals. Meanwhile, they enable compact optical constructions ideal for outdoor ranging devices.
Broad Adoption in Rangefinder & Electro‑Optical Hardware
Thanks to its unique wavelength features and feasible compact pulsed structure, 1535nm eye‑safe laser modules are frequently integrated into a wide range of end equipment:
- Handheld laser rangefinders
- UAV‑borne rangefinder payloads
- LiDAR and time‑of‑flight sensing systems
- Surveillance and electro‑optical observation units
- Portable distance measuring gear
- Defense‑grade rangefinder platforms
For OEM integration projects that need to balance small footprint, usable pulse energy and low repetition frequency, the 500μJ 10Hz 1535nm erbium glass laser serves as a reliable light source for portable and embedded rangefinding systems.
Why Choose 500μJ Pulse Energy
A 500μJ 1535nm Erbium glass laser offers a practical balance between pulse energy, system size, power consumption, and ranging capability. It sits between lower-energy 40μJ/200μJ modules and higher-energy 2mJ/10mJ lasers, making it well suited to compact systems that require stronger return signals without moving to a higher-power laser architecture.
Balanced Output for Compact Rangefinding
Compared with lower-energy 1535nm laser modules, 500μJ pulse energy provides more transmitted energy per pulse, which can help improve the available return signal in laser rangefinding and time-of-flight applications.
At the same time, it avoids the higher power demand, thermal load, and larger system requirements that may come with multi-millijoule laser sources.
Where 500μJ Fits in the Product Range
| Pulse Energy | Typical Positioning |
|---|---|
| 40μJ | Short-range sensing and ultra-compact modules |
| 200μJ | Compact ranging and low-power detection |
| 500μJ | Balanced solution for portable and compact rangefinders |
| 2mJ | Higher-output ranging and longer-distance applications |
| 10mJ | High-energy systems requiring stronger transmitted pulses |
For applications where 200μJ may provide insufficient signal margin but a 2mJ source would add unnecessary size or power demand, a 500μJ eye-safe laser provides a useful middle-ground solution.
Combined with a 1535nm wavelength and 10Hz repetition rate, this configuration is particularly suitable for OEM rangefinder systems that prioritize compact integration, moderate pulse energy, and controlled power consumption.
Typical Applications for 500μJ Erbium Glass Lasers
A 500μJ 1535nm Erbium glass laser is well suited to compact ranging and sensing systems that require a useful balance between pulse energy, package size, and power consumption. It is commonly considered for OEM applications where lower-energy modules may offer limited signal margin, while multi-millijoule sources would add unnecessary system complexity.
Handheld Laser Rangefinders
For portable distance measurement equipment, a 500μJ eye-safe laser can provide sufficient pulse energy for compact time-of-flight ranging while keeping the laser source relatively small and power-efficient.
Typical uses include:
- Handheld laser rangefinders
- Portable surveying devices
- Outdoor distance measurement systems
- Compact electro-optical instruments
UAV Rangefinding Systems
Weight, size, and power consumption are critical in airborne platforms. A 1535nm laser for UAV rangefinding can be integrated into compact electro-optical payloads where eye-safer wavelength operation and moderate pulse energy are required.
The 500μJ output level is suitable for systems that need stronger return signals without moving to a larger high-energy laser module.
Compact LiDAR
In compact LiDAR and time-of-flight systems, 500μJ pulse energy can support active distance measurement while maintaining a relatively low repetition-rate and compact laser architecture.
Potential applications include:
- Short- to medium-range LiDAR
- Terrain and obstacle sensing
- Industrial distance measurement
- Remote sensing modules
- OEM time-of-flight systems
For project integration, LOSHIELD can provide 500μJ Erbium glass laser modules according to wavelength, repetition rate, mechanical size, electrical interface, and OEM system requirements.
How to Select the Right Pulse Energy
Choosing the right pulse energy for a 1535nm Erbium glass laser depends on the required detection distance, target reflectivity, receiver sensitivity, optical aperture, beam divergence, repetition rate, and overall system design.
Higher pulse energy can provide a stronger returned signal, but it may also increase power consumption, thermal load, package size, and integration requirements. For this reason, the best laser source is not always the one with the highest pulse energy.
| Pulse Energy | Typical Use |
|---|---|
| 40μJ | Short-range sensing and compact optical modules |
| 200μJ | Compact measurement and low-power ranging |
| 500μJ | Portable laser rangefinders and balanced OEM systems |
| 2mJ | Higher-output and longer-range laser ranging |
| 10mJ | High-energy detection and specialized long-range systems |
Why 500μJ Is a Balanced Choice
A 500μJ eye-safe laser provides a useful middle ground between low-energy compact modules and multi-millijoule laser sources.
It is particularly suitable for:
- Portable and handheld laser rangefinders
- UAV rangefinding systems
- Compact LiDAR
- Time-of-flight measurement
- OEM electro-optical systems
For applications where 200μJ offers limited signal margin but 2mJ would introduce unnecessary size or power requirements, a 500μJ 1535nm laser module can provide a more balanced solution.
The final pulse energy selection should be based on the complete rangefinder or LiDAR system rather than pulse energy alone. Target characteristics, atmospheric conditions, receiving optics, detector sensitivity, and beam divergence can all affect achievable detection or ranging performance.
Frequently Asked Questions
Why is 1535nm considered an eye-safer wavelength?
The 1535nm wavelength is widely used in laser rangefinders and optical sensing systems because radiation in this spectral region is largely absorbed before reaching the retina.
