Enhanced Spectral Imaging with Tunable Laser Systems (TLS): In the realm of spectral imaging, tunable lasers, with their ability to meticulously adjust their output wavelengths, serve as the cornerstone for various spectral imaging applications. From the delicate tissues of a biological specimen to the robust components of industrial machinery, tunable lasers play a key role in identifying the composition of materials and imaging intricate features. This versatility not only enhances the precision of imaging but also expands the horizons of scientific discovery and technological innovation.

Spectrolight’s Tunable Laser System (TLS – based on the SL-Pico supercontinuum laser) revolutionizes spectral imaging by providing a single tunable light source solution covering a wide spectral range from 410 to 1700 nm. This significantly reduces operating costs and simplifies the imaging process by eliminating the need for hyperspectral cameras and individual optical filters.

Wavelength Tunability

The core attribute of tunable lasers is their wavelength tunability, which is the laser’s capacity to selectively alter its output wavelength within a specific range. This feature is indispensable for spectral imaging, as it allows for selective excitation of different fluorophores or chromophores within a sample. By tuning the laser to the precise absorption peaks of these molecules, one can achieve high-precision imaging results, which is crucial for applications that require discerning fine details or changes in the composition of the subject matter.

Bandwidth Tunability

The TLS-Red series of tunable laser systems provides simultaneous wavelength and bandwidth tunability. Tunable bandwidth refers to the adjustable FWHM wavelength output (in nanometers) over which a laser can be tuned. A broader tunable bandwidth allows for greater flexibility in imaging a diverse array of substances, as it can accommodate a wider variety of absorption and emission spectra. Lasers with a narrow tunable bandwidth are typically used for applications requiring high specificity, while those with a broad bandwidth are sought after for their versatility in imaging a multitude of materials. The choice of fixed versus tunable bandwidth is dictated by the application’s requirements, balancing the need for specificity against the desire for adaptability, for example.

Highlighted Applications

In spectral imaging, tunable lasers are used to illuminate a sample across a range of wavelengths. The reflected or transmitted light is then analyzed to determine the sample’s composition or to image its features. Spectral imaging applications are vast and varied, encompassing numerous fields where the unique capabilities of tunable lasers are leveraged:
