Laser Spectral-Power Integrating Sphere Test Station-Lisen Optics

The iSpec-VCS-IND Spectral Power Integrating Sphere Tester has been developed by LiSen Optics specifically for VCSELs and LDs which do not have high-frequency requirements and do not necessitate complex LIV, PCE functionality testing and analysis. This system is highly cost-effective, making it especially suitable for industrial users and automation integration manufacturers.

Main Technical Features

● Supports online integrated measurement and is available for secondary development by machine integrators.

● Measures key parameters such as spectral peak power, average power, peak wavelength, FWHM (Full Width at Half Maximum), and duty cycle.

● Frequency settings available for synchronous measurements triggered by both PD (Photodiode) and the spectrometer.

● Capable of measuring continuous and pulsed laser power, as well as spectral wavelength.

● Calibrated as per NIST standards. Based on the divergence angle and power of the DUT (Device Under Test), one can choose from different sizes of the power integrating sphere, ranging from 1 inch to 8 inches.

● Optional temperature control module available, with a temperature range of 5℃ to 95℃.

The industrial-grade iSpec-VCS-IND LIV Spectral Power Integrating Tester is primarily aimed at the LIV optoelectronic characteristics measurement of VCESL/LD and modules. Depending on the divergence angle and output power requirements of the VCESL/LD, one can select different specifications of integrating spheres, available in diameters of: 1 inch, 2 inches, 4 inches, 3 inches, 6 inches, and 8 inches. Given that the DUT might generate a significant amount of heat, which can significantly impact its output power and spectral wavelength, temperature control becomes essential. Thus, a temperature control module is available with a temperature range of 5℃ to +95℃.
