Product Overview

The Optilab TWL-CL-R is a high spectral purity and stable tunable wavelength laser source. The TWL-CL-R features wide wavelength tuning range, narrow laser linewidth, high Side Mode Suppression Ratio (SMSR), excellent wavelength stability and optical output level exceeding 30mW. With the standard Polarization Maintaining (PM) fiber output, the TWL-CL-R offers a linearly polarized output. These features make the cost-effective TWL-CL-R well-suited for many different applications, including DWDM device testing, optical
sensing, and laboratory measurement applications. The TWL-CL-R tunable laser is available in a standard 1U 19” rack-mountable housing, and includes an easy-to-use Labview control software and RS232 Interface for remote operation in laboratory environments.
