Continuous Slit Rotation and Aperture Adjustment
The ESL-9000C features 1x slit projection magnification and enables users to modify slit width continuously from 0mm to 14mm. The slit becomes a circle at 14mm. A helpful scale on the knob indicates the width value. The slit height also can be changed continuously, from 1mm to 14mm. Aperture diameters are Ø14mm, Ø10mm, Ø5mm, Ø2mm, Ø1mm, and Ø0.2mm. The slit angle is continuously adjustable from vertical to horizontal from 0° to 180°. Four steps of slit inclination—5°, 10°, 15°, 20° — also are available for oblique illumination in contact lens evaluations.

High Clarity Luminance and Built-in Filters
The ESL-9000C utilizes a 12-volt, 30-watt halogen bulb that provides incredible clarity. Four built-in Illumination Pathway Filters can be effortlessly inserted into the illumination pathway using the selection lever. Options include a heat absorption filter that aids in patient comfort during lengthy exams, a red-free filter that enhances structural contrast, a cobalt blue filter for use in fluorescein assessment, and a grey filter. When indirect retro-illumination is needed, you can easily deflect the illumination light using the unit’s well-placed controls. In addition, the ESL-9000C features a diffusion lens for enlarging the illumination field as well as for observation and photography at low magnification.

Joystick with Shutter Button
The integrated Joystick is simple to control and allows operators to acquire sharp images using the shutter button. The base operation of the ESL-9000C offers the following movements to provide flexibility, comfort and precision—forward and back movement to 90mm; left and right movement to 100mm, fine movement to15mm and vertical movement to 30mm. The joystick moves horizontal for fine-tuning and vertical for height and target alignment. Once you achieve the proper alignment, the base can be locked to prevent sliding.
