Work Table Included Haag-Streit Style Tower Illumination The GR-54 utilizes a Haag-Streit Style Tower Illumination System that sits above the observation system, allowing the illumination column to be decoupled in the vertical meridian. This allows greater flexibility when minimizing unwanted reflections during gonioscopy and increases the peripheral field of view during indirect ophthalmoscopy. Galilean Optical System The advanced optics in the GR-54 offer excellent performance as well as the flexibility to connect technologically advanced imaging systems. A revolving drum allows for quick change of magnification, while an optional beamsplitter allows for video camera attachment. And, like all Gilras Slit Lamps, the GR-54 features superior quality optical crystal. Five-Position Revolving Drum Magnification The Gilras GR-54 offers a five-position drum magnification that can be easily switched throughout the exam. Using the conveniently located knob, the unit offers total magnification ratios equivalent to 6x (?34.7mm), 10x (?22mm), 16x (?13.5mm), 25x (?8.5mm) and 40x (?5.5mm) with the 12.5x eyepiece. Pupil Distance and Diopter Adjustment The GR-54 features an adjustable prism box that allows practitioners to easily set interpupillary distance from 52mm to 78mm. Using the unit's carefully-designed rings, diopter also can be precisely adjusted to ±6D. Brightness Control and Outstanding Binocular Field of View The Gilras GR-54 features a brightness dial that offers practitioners complete control over light intensity. The unit's Galilean Optical System also offers a very large binocular field of view of ?34.7mm, ?22mm, ?13.5mm and ?8.5mm and ?5.5mm, with the 12.5x eyepiece. The illumination light can also be decentered by loosening the centering knob and swinging the slit width control knob. Outstanding Luminance with Built-in Filters The GR-54 utilizes a 6-volt, 20-watt halogen bulb that provides outstanding luminance. Using the selection lever, practitioners can choose from four built-in Illumination Pathway Filters. 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. Continuous Slit Rotation and Aperture Adjustment With the GR-54, practitioners can modify slit width continuously from 0mm to 14mm. The slit becomes a circle at 14mm. The slit height also can be changed continuously, from 1mm to 14mm. Seven aperture diameters (14mm, 10mm, 5mm, 3mm, 2mm, 1mm, 0.2mm) provide a clear, broad field of view. The easy-to-use controls on the GR-54 allow you to rotate the slit image at any angle in the vertical or horizontal direction, from 0° to 180°. Four steps of slit inclination—5°, 10°, 15°, 20° — also are available for oblique illumination in contact lens evaluations. Integrated Joystick with Shot Button The integrated Joystick is simple to control and allows operators to acquire sharp images. The base operation of the GR-54 offers the following movements to provide flexibility, comfort and precision—longitudinal movement to 90mm; lateral 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. Quality Craftsmanship The Gilras GR-54 was built using high quality aluminum and bronze, making this unit not only an excellent performer, but a durable one as well. Flexibility to Add On Accessories No matter how detailed your exam needs are, the GR-54 can adapt to meet them. The unit can easily incorporate accessories such as a beamsplitter, camera, video and tonometer.
