ESL-7800 Ezer Slit Lamp 5 Step Magnification

The Ezer ESL - 7800 is the top quality Slit Lamp form our series.
It is built with a traditional toer style configuration and and it presents specialized optics and increased magnifications levels. The ESL - 7800 uses a Galilean Optical System.
The modern design presented by the ESL - 7800 model presents a "six-position revolving magnification drum" that allows an easier exchange of the magnification levels from 6x, 10x, 16x, 25x to 40x than exchanging an eyepiece.

Magnification Select Dial
Five steps magnification range from 6x to 40x without changing the eyepiece, only twisting a single knob.

Optic System
The ESL - 7800 Slit Lamp presents an optic system ideal for technically advanced imaging systems.
Through the utilization of the optical beam slitter that presents an 'in-out' prism system, the ESL - 7800 Slit Lamp allows maximum illumination to the practitioner during the observation and at the same time to the digital and video imaging system when it is in position.
This dual port beam splitter permits an assistantscope to be attached.

Fixation target
Two kinds of fixation targets are available.One is for diopter adjustment to help the patient to see the target clearly while the other is illuminated at a fixed spot.

* Hurby Lens Guide Plate
* Prism box: Separates the prism box to adjust the interpupilar distance.
* Diffusion Lens: Used to observing and photograph at a low magnification, and to enlarge the ilumination field.
* Lamp cap
* Apertue Slit Height and Display window.
* Filter Selection Level: There are four filters for selection.
* Reflecting mirror: Both long and short reflecting mirrors are provided. The long mirror is routinely used for most examination procedures. The short mirror is used when the long mirror interferes with the observation pathway, such as during funduscopy.
* Hruby Lens: Used for observation of fundus and the posterior segment of vitreous body.
* Slit with control knob: The slit width is continuously adjustable within the range from 0 to 9mm. The marks on the left knob stand for the approximate value of the width.
* Ilumination Inclination Lever: Four 5° inclination stops are available-up to 20°.
* Single-handed elevation system.
* Easy-to-reach tilt mechanism gonioscopy.
* Dial-in, and continuously variable aperture setting from 10mm to 0.2mm.
* Focusing fixation light is adjustable to each patient.
* Hallogen ilumination standard.
* Five built-in filters.
