Overview
Specifications
| Parameter | Value |
|---|---|
| Gas Detection | TDLAS,TDLAS Tunable Diode Laser Absorption Spectroscopy, Tunable Semiconductor |
| Package | 14 Package, TO39 Package, TO56 Package |
| Current Center Wavelength | +/-1nm |
| Packaging options | 14-pin butterfly package, TO39 (with TEC), TO56, DX-1 module (driver and TEC) |
| Off-axis configuration | The laser is incident into the resonant cavity composed of high reflectivity mirrors at an off-axis angle to avoid direct resonance between the laser and the cavity mode |
| integral effect | The beam undergoes multiple reflections in the cavity, forming a dense spot pattern, effectively increasing the absorption optical path |
| Light intensity integral | The detector measures the sum of all transmitted light, not individual modes |
| No cavity mold matching required | Overcomes the requirement of traditional cavity-enhanced spectroscopy technology for accurate matching of laser frequency and cavity mode |
| Long effective optical path | Often several kilometers or even longer |
| High sensitivity | Detects low concentration gases or weak absorption |
| Broad spectral range | Suitable for continuous light sources or broadband light sources |
| Ultra high sensitivity | Can detect ppb (10-9-9) or even ppt (10-12-12) level gas concentration |
| long optical path | The effective light absorption distance can reach several kilometers, far exceeding the traditional multi-pass pool (such as White pool, Herriott pool) |
| compact structure | Compared with traditional long optical path absorption cells, the CEAS system is small in size and highly stable |
| Wide applicability | Can be used in ultraviolet, visible, near-infrared and mid-infrared bands |
| Environmental monitoring | Detection of trace gases such as NO2NO2, CH4CH4, CO2CO2, H2OH2O, etc. in the atmosphere |
| industrial process control | Semiconductor manufacturing, combustion analysis, chemical reaction monitoring |
| medical diagnosis | Breath analysis (such as NONO testing for asthma diagnosis) |
| Laboratory spectroscopic research | Molecular spectroscopy, isotope ratio measurements |
| Miniaturization & Portability | Combining quantum cascade laser (QCL) and optical frequency comb technology to develop portable CEAS equipment |
| Multi-component detection | Combined with broadband light sources (such as supercontinuum lasers) to achieve simultaneous measurement of multiple species |
| Artificial intelligence assistance | Use machine learning to optimize spectral inversion algorithms and improve detection accuracy |
