Product Overview:

488nm, 150mW Blue Laser Source System Overview

The OBIS laser system employs Optically Pumped Semiconductor Laser technology to provide industry-leading beam quality, stability, and low-noise performance at 488nm. These systems are used extensively in flow cytometry and fluorescence spectroscopy applications. OBIS lasers deliver high optical power with low noise and high beam quality. The complete turn-key system is flexible and can be rapidly integrated into a wide range of applications.

Complete Turn-Key 488nm Laser System

The all-inclusive OBIS system includes the laser head and power supply, remote controller and all interconnect cables. The laser system is operated remotely via USB or RS232, and the PC control software is included. The laser includes features to ensure a long operating lifetime, and to help protect the laser operator. The key switch prevents unauthorized use, and the external interlock allows a remote safety switch to be wired. The remote controller includes a Laser Ready and Laser On indicator, as well as a front panel Fault indicator. Accommodation is provided for driving a cooling fan, and for temperature stabilization the OBIS laser head can be mounted to the OBIS fan-heatsink.

Quick Start Guide


This video above summarizes the setup process, including mounting the laser head on the optional heatsink. Control inputs are located on the laser head for OEM applications where the laser head is directly controlled with custom software.

Operating Flexibility with Multiple Modulation Modes

The OBIS laser can be operated in CW mode, or modulated in multiple modes: analog signals, digital signals, and combined analog/digital signals. The laser can be modulated to full-off output, ensuring no photons are emitted. LS modules can be modulated to full-off output using the digital modulation mode, while the LX modules can be modulated to full-off using the analog modulation mode with a Blanking Enabled feature.

Laser System Options and Availability

The turn-key OBIS laser sources are available in a wide range of wavelengths and output powers, either fiber-coupled or with a free-space output, and multiple sources can be simultaneously operated from a single computer. When application requirements change, laser heads of different wavelengths are speedily exchanged on the bench.

Two free-space laser models are available at 488nm:
  • The LX model can be digitally modulated up to 150MHz, 500kHz analog. Maximum output power models: 50mW, 100mW, 150mW.
  • The LS model can be digitally modulated up to 50kHz, 100kHz analog. Maximum output power models: 20mW, 60mW, 80mW, 100mW, and 150mW.

  • A number of bandpass filters are available for the free-space laser heads, and are useful in applications that benefit from reduced noise at longer wavelengths. Filters are available at 445nm, 473nm, 488nm, 633nm, and 640nm, and attach directly to the front of the laser head.

    A selection of multi-laser accessories are available: two six-laser controller models for OEM and benchtop applications, a heatsink with integrated cooling fan, and an integrated mounting and control system that incorporates independent laser controllers, modulation inputs, and thermal management for up to five OBIS laser heads.
