G5 Integrated Spectral Bench (ISB5)
- Broad tuning range
- Narrow linewidth
- Stable fiber-coupled output
- Flexible control

About the product
The Broadband Tunable External Cavity Laser Integrated Spectral Bench (ISB5) is a compact, self-contained tunable laser solution from DAYY Photonics. Built on a semiconductor gain module with an integrated tunable filter, the ISB5 delivers stable fiber-coupled output across a broad tuning range with narrow linewidth performance. Featuring turnkey design and flexible control options, it is well-suited for precision research, test, and measurement applications.
A user-friendly GUI is included with this product, which allows the user to select between manual, stepped sweep, and continuous sweep modes. Operating parameters for each mode can also be set within the GUI, and direct readout of the operating wavelength is also provided.
The laser can also be operated without the software GUI via Modbus protocol with serial commands, which requires the instrument to be connected to the PC using the RS-232 or USB ports.
- Center wavelengths available: 785nm, 850nm, 930nm, 980nm, 1050nm, 1210nm, 1250nm, 1300nm, 1350nm, 1410nm, 1550nm, 1590nm, 1625nm, 1680nm
