Illuminators

Your purchase of the Dolan­Jenner Fiber-Optic Illumination
System will provide you with
many years of service in a large
variety of applications which
require high intensity, yet cool
illumination. Please read the
following instructions to ensure
that maximum performance is
obtained from your system.

INTRODUCTION

The 190-1 Fiber Optic Illuminator gives high-intensity "cold" light
where you need it most. The fiber optics absorb heat and transmit
high-intensity light, and the gooseneck light pipe lets you position the
lens from a variety of oblique angles.

It is ideal for illumination in temperature-sensitive applications such
as specimen preparation, dissection, culture work or
micromanipulation. The illuminator can also be used in conjunction
with a stereomicroscope lamp port for incident or transmitted
illumination with or without the lens.

FEATURES

A powerful 0.19 inch (4.8mm) diameter fiber optic that provides
over 4,000 foot candles at a 6 inch distance in a 0.87 inch (22mm)
diameter spot of high intensity "cold" light.

A 30 watt quartz-halogen vibrationless source (convection-cooled) at
a color temperature of 3100 degrees K, suitable for tungsten film.

Gooseneck flexibility is excellent for multipositioning. The fiber
optic light pipe always remains at the ambient temperature and is
safely handled at all times to enable optimum positioning for reduced
glare. This eliminates the possibility of burnt fingers on adjustment
and, at the same time, increases eye comfort.

Convenient 28mm focal length, slide-lock lens which is quickly
focused to provide light spot diameters from 0.16inches to 2.87 inches
(4mm to 73mm).

The four position light intensity switch offers easy light-intensity
selections.

CHANGING THE ILLUMINATOR LAMP

The following procedure outlines the steps necessary to replace the
lamp.*:

1. Unplug the illuminator from the wall socket before disassembling
the unit.

2. If the light pipe must be removed to take off the cover, unscrew it by
straightening it as much as possible and turning it counterclockwise
while grasping it at the base. This step is only necessary if the light
pipe is permanently mounted.

3. Remove the 4 button-head screws using a 5/64" Hex Allen wrench.
Lift off the cover assembly slowly until the lamp is exposed.

4. Unplug the lamp from its socket.

5. After the lamp is disconnected unsnap it from the lamp retainers on
the bracket. (Figure 1).

6. Reverse this process to install a new lamp.

*Note: Use only EKZ replacement lamps.
