Dolan-Jenner Industries of Boxborough, MA, a manufacturer of fibre optic components and fibre optic illumination systems, has introduced Fiber-Lite MI-157F fibre optic illuminator. Ideal for controlled lighting applications, the MI-157F features 1,000-plus hours of lamp life, a manual iris for maintaining colour temperature, an IR filter and holder to block damaging IR wavelengths, and a 25mm ID input port for versatility and adaptability.

The MI-157F is supplied with an extended life EKE-X lamp, rated for 1,000 hours at full intensity, 2,000 hours at 90 per cent and 4,000 hours at 80 per cent intensity. Operating at 80 per cent intensity can result in two years of standard operating time from only one lamp.

An IR filter and holder is included, with room for an additional 25mm filter, which protects samples from damaging IR heat. The filter is easily accessed through the lamp access door and no tools are required to remove or add a filter.

The illuminator also features a 25mm fibre input opening to accept almost any light guide and adapter combination. A front panel manual iris is convenient and easy to use, and by using the iris, intensity adjustments can be made while maintaining a constant colour temperature.

The MI-157F is made with a stackable heavy duty ABS plastic housing, which is ideal for the laboratory and rugged enough for industrial environments. The illuminator is also dependable and safe, featuring thermal protection and certifications from UL, CE, and C-UL.
