Clean and in good, working condition. Unit powered up and 3 of the 4 lasers lit up. 405, 488, 639nm all fired. 555 did not. We do not know if this dead line is from the excitation source, connection or line.
Comes as shown with 4 laser connections, Scan Module cable, ground line and power cable.
Warrantied to be as described.
Manufacturer Description
The LASOS LSM-700 Laser Rack is a high-stability, multi-wavelength excitation engine purpose-built for the Carl Zeiss LSM 700 Laser Scanning Confocal Microscope platform. This multi-line laser engine integrates independent, high-performance solid-state diode lasers into a single, compact rack-mount chassis with integrated cooling and power management electronics. Utilizing proprietary polarization-preserving, single-mode pigtail fiber couplings, the LSM-700 rack delivers exceptional beam quality and precise real-time intensity control via the microscope's Acousto-Optical Tunable Filters (AOTF). This unit represents an exceptional source for clinical lab replacement parts, academic instrumentation builds, or individual laser module reclamation.
Technical Specifications
- System Compatibility: Carl Zeiss LSM 700 Confocal Microscope Systems
- Laser Line 1 (405 nm): Diode Laser, 5 mW Output — TESTED & WORKING
- Laser Line 2 (488 nm): Diode Laser, 10 mW Output — TESTED & WORKING
- Laser Line 3 (555 nm): Diode Laser, 10 mW Output — NON-OPERATIONAL / FAILED TO FIRE
- Laser Line 4 (639 nm): Diode Laser, 5 mW Output — TESTED & WORKING
- Fiber Coupling Architecture: Polarization-preserving single-mode fiber optic pigtails
- Input Voltage Range: Universal 100V - 240V, 50/60 Hz switching power supply backplane
- Value-Add: Features the original integrated LASOS multi-channel power distribution backplane, internal optical combiners, and three fully operational, high-value excitation diode modules with pristine fiber outputs.
System Compatibility & Condition Disclosure
This LASOS rack interfaces with the standard Zeiss Axio-series configuration but is sold under partial functionality restrictions:
- Microscope Interfaces: Integrates natively with Zeiss Axio Observer Z1 (inverted) and Axio Imager M2 (upright) confocal frames.
- Control Software: Fully recognized under Zeiss ZEN (Black) imaging suites for pixel-precise region of interest (ROI) illumination.
- Condition Disclosure: This unit is listed explicitly for parts or repair. While the 405nm, 488nm, and 639nm modules fire normally with stable beam paths, the 555nm line does not respond. Perfect as a donor unit to revive a downed confocal stack.
Applications
An invaluable asset for biomedical core facilities, custom optical engineering benches, and service depots:
- Confocal Station Reclamation: Providing three working excitation lines to instantly swap into an aging or heavily degraded Zeiss LSM 700 installation.
- Fluorescence Microscopy: Sourcing high-grade, fiber-coupled 405nm (DAPI/Hoechst), 488nm (GFP/Alexa488), and 639nm (Cy5/Alexa648) lasers for independent optical paths.
- Core Component Sourcing: Harvesting premium LASOS power controllers, cooling blocks, and specialized single-mode fiber arrays.
