The Dolan-Jenner Fiber-Lite MI-150 is a high-intensity 150 W quartz halogen fiber optic illuminator designed primarily for microscopy and general laboratory illumination applications. The supplied photograph clearly shows the Fiber-Lite MI-150 High Intensity Illuminator label and Dolan-Jenner branding. The MI-150 provides a high-output visible light source that can be coupled with compatible fiber optic light guides for directed, cold illumination of specimens and work areas.

The MI-150 uses a 21 V, 150 W quartz-halogen lamp and incorporates a front-panel solid-state intensity control, allowing the operator to adjust illumination according to the application. Dolan-Jenner documentation states that the MI-150 can deliver up to approximately 350,000 footcandles when used with appropriate fiber optic light guides.

The illuminator is designed to accept compatible Fiber-Lite fiber optic systems through its fiber optic nosepiece. The standard MI-150 configuration uses a 15 mm fiber input, making it suitable for compatible gooseneck, ring-light, and other fiber optic illumination assemblies.

Applications

The Fiber-Lite MI-150 is commonly used for microscopy illumination, where bright, controlled light needs to be delivered to a specimen through a fiber optic light guide. It can provide illumination without placing a conventional lamp directly at the microscope or specimen, making it useful for laboratory inspection and imaging applications.

The unit can also be used for general laboratory illumination, optical inspection, machine vision-related illumination, and other applications requiring a high-intensity fiber optic light source. Compatible fiber optic accessories can be selected according to the desired illumination geometry, including gooseneck and ring-light configurations.

Technical Specifications

The specifications are based on Dolan-Jenner technical documentation for the MI-150 series. The exact mains-voltage configuration of the photographed unit should be verified from its rear nameplate before connection.

Benefits of Refurbished Laboratory Equipment

Purchasing refurbished laboratory equipment can provide laboratories, universities, research facilities, and industrial organizations with access to specialized illumination equipment at a lower cost than purchasing new instrumentation. A refurbished Fiber-Lite MI-150 can be particularly useful for microscopy and optical inspection setups requiring a powerful fiber optic light source.

The MI-150's variable intensity control and compatibility with multiple fiber optic light-guide configurations make it a versatile illumination source. Refurbished equipment can also be a practical choice when maintaining existing microscopy or laboratory systems that use compatible Fiber-Lite accessories and light guides.

Additional Information

The supplied photograph shows the Dolan-Jenner Fiber-Lite MI-150 High Intensity Illuminator. The unit is photographed with its front intensity control and fiber optic connection visible. Fiber optic light guides, goosenecks, ring lights, adapters, replacement lamps, and other accessories should not be assumed to be included unless specifically stated in the sale.

The MI-150 is available in different factory-configured electrical versions. The exact voltage configuration and installed lamp condition of the supplied unit should therefore be verified before purchase and installation. The physical condition shown in the photograph also indicates visible cosmetic wear and dirt consistent with used laboratory equipment.
