Applications

TDLAS (Tunable Diode Laser Absorption Spectroscopy) is a highly sensitive and selective gas detection technology based on the characteristic absorption spectral lines of gas molecules. Different gases exhibit unique absorption properties at specific wavelengths; when the laser wavelength scans across the target gas's absorption line, the gas absorbs a portion of the optical energy. By measuring the change in light intensity after the laser passes through the gas and applying the Beer-Lambert law, the concentration of the target gas can be accurately calculated.

Box Optronics focuses on R&D and production of laser devices, supplying Ytterbium-doped Fiber Amplifiers, suitable for multiple scenarios. It’s used to amplify optical signals in 1030~1080nm band. Its output power is 17~40dBm optional, with advantages of high gain and low noise. We support bulk purchase and customization consultation, with compliant parameters and stable performance, which can meet various optical signal amplification needs in scientific research and industrial fields.

The SLED (Superluminescent Diode) serves as the core broadband, low-coherence light source in OCT systems. Its broad spectral output provides a short coherence length, enabling high axial resolution, while its low-coherence characteristics ensure that interference signals are generated only when the optical path lengths of the sample and reference arms are matched—thereby facilitating high-contrast, high-resolution tomographic imaging.

EDFA (Erbium-Doped Fiber Amplifier) is used to amplify weak optical signals directly in the optical domain, extending transmission distance with high gain and low noise for fiber communication and sensing systems.
