Product description

Solid-state red/green laser diode illuminator (555nm & 640nm) for fluorescence microscopy and live-cell imaging.

The 89 North LDI-R-G-WF is a solid-state red/green laser diode illuminator designed as a standalone microscopy light source for advanced fluorescence imaging applications in biotechnology, molecular diagnostics, and biomedical research. It emits dual wavelengths at 555 nm (green) and 640 nm (red), with output power up to 1000 mW per channel, enabling multi-channel fluorescence excitation essential for live cell imaging, confocal microscopy, and photostimulation experiments.

Key technical features include:

  • Laser Diode Lamp Type with stable wavelengths at 555 nm (range 553–555 nm) and 640 nm (range 632–643 nm)
  • Independent shutter and intensity control for each wavelength channel via MicroManager and LDI GUI software, facilitating precise modulation in fluorescence microscopy workflows
  • Connection via a 3 mm liquid light guide, compatible with major microscope brands possessing suitable collimating adapters
  • Fully tested and serviced unit, ensuring reliability and performance in live-cell imaging and multi-channel fluorescence analysis
  • Suitable for integration into bioprocessing, synthetic biology, and molecular cloning workflows where stable and tunable excitation sources are critical

This illuminator supports diverse microscopy techniques widely adopted in biotechnology research, including confocal microscopy, fluorescence imaging, and photostimulation experiments, making it a critical tool in biopharmaceutical production pipelines and molecular diagnostics laboratories.

Included with the unit are all necessary accessories such as the 3 mm liquid light guide and full remote installation and training services, providing seamless setup for research labs focusing on advanced fluorescence applications.

This laser diode illuminator is extensively tested for optical output at both wavelengths and interlock safety features, offering a fully functional, reliable light source that meets the demanding needs of modern microscopy and biotechnology research facilities.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
