New Product Recommendation丨ATG7500 Series Laser-Driven White Light Source (LDLS)
2025-09-12
In the field of spectral analysis, the performance of the light source is often a critical factor determining detection accuracy and application scope. Traditional light sources, such as halogen and xenon lamps, have limitations in brightness, spectral range, and lifespan, which have long restricted the development of high-end spectral applications. ATG7500 Series Laser-Driven White Light Source (LDLS), launched by Optosky, fundamentally transcends the performance boundaries of traditional light sources with its cutting-edge laser pumping technology and plasma emission mechanism, offering revolutionary solutions for semiconductor inspection, life sciences, environmental monitoring, and other fields.
01 Technological Innovation: The Leap from Electroluminescence to Laser-Driven
The Laser-Driven Light Source (LDLS) is an ultra-bright, broad-spectrum light source that uses a high-energy focused laser beam to drive a xenon plasma. This product series demonstrates exceptionally high luminous brightness across a spectral range from 170 nm to 2100 nm. For instance, its brightness in the DUV+ (170 - 300 nm) band is more than 10 times that of traditional light sources like xenon lamps. Furthermore, compared to traditional light sources, its operational lifespan is significantly extended by an order of magnitude, exceeding 9000 hours.
The core advantage of the ATG7500 series stems from its unique working principle. Traditional electroluminescent light sources rely on electrode discharge to excite gas for light emission, whereas the LDLS utilizes laser-pumped plasma technology: a 65W/30W laser beam is focused to excite a xenon medium, forming a high-energy plasma with a diameter of only about 100μm. When electrons, excited by the laser, transition to higher energy levels and then return to the ground state, they release broad-spectrum photons covering 190-2500nm.
This electrode-free drive design brings three major breakthroughs:
-
Brightness increased by more than 10 times: In the deep ultraviolet band (170-300nm), the ATG7500's spectral radiance can reach 185mW/(mm²・sr・nm), far surpassing traditional light sources like xenon lamps.
-
Lifespan extended to 10,000 hours: Eliminates electrode wear, reducing consumable costs by over 70%.
-
Spectral stability of 0.15% STD: The fluctuation of the plasma centroid position is less than 0.15μm, ensuring the reliability of long-term measurement data.
02 Performance Advantages: Redefining the Standards for Broad-Spectrum Light Sources
Ultra-Broad Spectral Coverage and Flat Distribution
ATG7500 series achieves full-band coverage from ultraviolet (190nm) to near-infrared (2500nm), with a uniform spectral power density distribution. Comparative data shows its intensity in the deep ultraviolet band is more than 10 times greater than that of traditional deuterium lamps, providing more precise absorption and scattering measurements for applications such as semiconductor photoresist inspection and UV spectral imaging.
ATG7500-30 Output Spectrum
High-Brightness Point Source and Efficient Coupling
With a plasma size of 175μm × 415μm, it serves as an ideal hundred-micron-level point source. Coupled with a Numerical Aperture (NA) of 0.4-0.6, it can be efficiently coupled into a 600μm optical fiber (coupling efficiency > 0.53W) or a spectrometer slit, making it particularly suitable for imaging and analysis of precision samples like microchips and biological cells.
Long Lifespan and Low Maintenance Costs
Traditional xenon lamps typically last only 1000-2000 hours. The electrode-free design of the ATG7500 series extends the light source's lifespan to over 10,000 hours. This means calibration intervals are extended by 5 times, significantly reducing maintenance costs in both research and industrial applications.
