Obis Galaxy

Share this on social media:

Coherent has released the Obis Galaxy, which combines the output of up to eight separate lasers, spanning the 405nm to 640nm wavelength range, into a single-mode fibre. The product is designed to simplify laser implementation in multi-wavelength applications, for both laboratory users and OEM instrumentation manufacturers.

Using high-precision FC connectors, lasers can be replaced with greater than 85 per cent repeatability in power at the output fibre. This enables lasers to be ‘hot swapped’ in the field, either to add extra wavelengths or upgrade the power at specific wavelengths. Moreover, Obis Galaxy is designed as a flexible and open-architecture platform; it supports both direct plug-and-play with Coherent’s line of Obis FP smart laser modules, as well as other visible lasers via an optional (high-precision FC to APC) fibre optic adaptor cable. In addition, Obis Galaxy operates over a 10-50°C temperature range and is shock/vibration tested.

The main applications for Obis Galaxy will be in bioinstrumentation, including flow cytometry and confocal microscopy, where multiple wavelengths enable simultaneous and/or tandem use of multiple fluorescent probes and markers.
