Advanced Optic System

The optics in the ESL-7800 Slit Lamp are ideal for technologically advanced imaging systems. An optical beamsplitter 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 beamsplitter also allows an assistantscope to be attached.  


Magnification Selection Dial

Operators can select from five steps of magnification simply by twisting a single knob. Changing an eyepiece is not required. Using the conveniently located knob, operators can select from total magnification ratios equivalent to 6x (Ø33mm), 10x (Ø22.5mm), 16x (Ø14mm), 25x (Ø8.8mm), 40 (Ø5.5mm).


Large Binocular Field of View with Wide Range of PD and Diopter Adjustment

Ezer's ESL-7800 Galilean converging optical system offers a very large binocular field of view of Ø33mm, Ø22.5mm, Ø14mm, Ø8.8mm, and Ø5.5mm, with a 55mm-75mm range of PD adjustment and -5D to +3D diopter adjustment.  


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.
