Designed in the traditional tower style configuration, the ESL-7800 offers specialized optics, greater magnification levels and wide field-of-view. It boasts an advanced Galilean Optical System and a five-step revolving drum that allows for an easier exchange of the magnification levels than exchanging an eyepiece.

 

Magnification Select Dial:

Five steps of magnification range fro 6x o 40x without changing the eyepiece. Simply twist the knob.

 

Optic System:

The optics in the ESL-7800 Slit Lamp are ideal for technologically advanced imaging systems. An optical beam splitter featuring an "in-out" prism system allows maximum illumination to the practitioner during observation and likewise enables to digital and video imaging systems when these tools are in position. The dual port beam splitter also allows an assistant scope to be attached.

Two Fixation Targets:

 The ESL-7800 offers two options with respect to fixation targets. One is for diopter adjustment to help the patient to see the target clearly while the other is an illuminated fixed spot. The fixation target with diopter compensation supplies a dot and concentric circles target. Operators simply slide the knob to adjust the diopter compensation within the range from -15D to +10D. The fixation target with spot light is especially well suited to patients with refractive errors exceeding -15D.

Continuous Slit Rotation and Aperture Adjustment:

The ESL-7800 features 2/3x slit projection magnification and enables users to modify slit width continuously from 0mm to 9mm. The slit becomes a circle at 9mm. A helpful scale on the knob indicates the width value. The slit height also can be changed continuously, from 1mm to 8mm. Aperture diameters are Ø9mm, Ø8mm, Ø5mm, Ø3mm, 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.

 

Ergonomicaly Designed Illumination Control:

The smooth classic design of the ESL-7800 allows for precise movements and easy operation of the joystick and knobs. For example, the illumination lever is conveniently located next to the joystick. The brightness control switch can be set to High or Normal, making diagnostic procedures even easier.

Accessories Mount:

This ESL-7800 slit lamp can be equipped with the R-900 Goldman applanation tonometer as well as several other accessories, including video accessories.

 

 

Fundus Observation:

Unlike standard slit lamp units, Ezer's ESL-7800 also allows for a dilated examination of the fundus and the posterior segment of the vitreous body using a Hruby Lens with the unit's Hruby Lens Holder and Hruby Lens Guide Plate.

 

 

High Clarity Luminance and Built-in Filters:

The ESL-7800 utilizes a 6-volt, 20-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.

Integrated Control Joystick:

The integrated Joystick is simple to control and allows operators to acquire sharp images. The base operation of the ESL-7800 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.
