TLS-Red Adjustable-Bandwidth

TLS-Red is the likely starting point when:

• You need to tune the selected center wavelength and control the FWHM bandwidth.
• Your measurement requires different spectral widths at different wavelengths or test conditions.
• You are developing or characterizing an imaging, spectroscopy, detector, or optical system across multiple spectral bands.
• A fixed 10 or 20 nm bandwidth does not provide enough flexibility.
• You need one wavelength-selectable source rather than aligning several independent laser sources.

If you need wavelength tuning but can keep bandwidth fixed at 10 or 20 nm, start with TLS-Blue instead.

If you need the full broadband supercontinuum spectrum rather than wavelength-selected output, start with SL-Pico.

Hyperspectral and Multispectral Imaging

Adjustable wavelength and spectral bandwidth can support hyperspectral camera development, spectral imaging, image-system calibration, wavelength-dependent illumination studies, and other applications where both illumination wavelength and passband width matter.

Semiconductor, Wafer and Display Inspection

Spectrolight specifically demonstrates the TLS platform for silicon wafer inspection. Tunable illumination can also support optical inspection, micro-LED analysis, camera testing, component QC, and wavelength-dependent transmission or reflection measurements.

Spectroscopy and Material Characterization

Potential uses include photoluminescence, absorption and reflectance measurements, Raman-related research, thin-film and nanomaterial characterization, transient absorption, and other spectroscopic experiments that benefit from controllable wavelength and bandwidth. Spectrolight lists these among current TLS application areas.

Microscopy and Bio-Imaging Research

Wavelength-selectable illumination can support fluorescence and confocal microscopy, optical absorption studies, biomedical imaging research, and related laboratory applications where controlled spectral illumination is useful.

Detector, Camera and Optical-System Characterization

TLS-Red can be considered for spectral responsivity measurements, camera and image-sensor characterization, filter/component testing, reflectance/transmittance measurements, and calibration-system development.

What is the Spectrolight TLS-Red?

TLS-Red is a picosecond tunable laser system that combines a broadband supercontinuum source with wavelength-selection technology. It allows users to select a center wavelength and adjust spectral bandwidth within the supported range.

What wavelength range does TLS-Red cover?

Depending on configuration, TLS-Red can provide tunable output across selected VIS, IR, SWIR, or custom ranges within the overall 410–1700 nm TLS platform.

What bandwidth can TLS-Red provide?

TLS-Red provides adjustable FWHM bandwidth, nominally about 2–15 nm depending on wavelength and system configuration. At longer wavelengths, the supported minimum and maximum bandwidth differ, so the exact requirement should be checked against the selected configuration.

What is the difference between TLS-Red and TLS-Blue?

Both systems provide wavelength-selectable picosecond output. TLS-Red allows spectral bandwidth to be adjusted, while TLS-Blue uses a fixed 10 or 20 nm bandwidth.

How do I choose a TLS-Red configuration?

Start with the required wavelength range, spectral bandwidth, optical power, pulse width, repetition rate, timing requirements, and application. RPMC can then help narrow the available supercontinuum source and wavelength-selection configurations.
