Compact and robust spectrometers with fully customizable range and resolution parameters, able to measure pulsed and continuous lasers.
Utilizing the principle of non-moving parts just like the well known HighFinesse WS Series Wavelength Meters, our Spectrometers offer the time-tested robustness and ability to measure both pulsed and cw lasers! Most importantly, a multitude of possibilities are open for tailoring the resolving power and spectral bandwidth of the device according to our customers’ needs.
LSA Laser Spectrum Analyzer
The LSA utilizes an echelle grating and a low order grating in two separate beam paths. The echelle grating provides the LSA with its high resolving power, enabling high accuracy measurements. The low order grating makes it possible to overcome the wavelength indeterminancy of the echelle grating.
Linewidth Measurement
Our OSAs always include the linewidth option automatically. The linewidth can be determined through multiple calculation methods (please contact us for details), and we can accomodate a wide range of customer requests regarding the algorithms used.
External Trigger Option
All LSAs detect and measure pulsed signals automatically. Additionally, this option allows the user to trigger pulsed measurements externally. The TTL option guarantees synchronization between pulsed excitation and measurement. It provides low-noise signals without parasitic parts when measuring pulsed signals with low duty cycles.
Casing
We are happy to customize the casing of the LSA on your request, including standard 19" casings, and cleanroom-suitable devices.
Typical Applications
Multi-line or broadband spectra of light sources up to 2 THz like cw and pulsed lasers, gas discharge lamps, super luminescence diodes, semiconductor laser diodes and LEDs.
