Keeler Portable Slit Lamp (PSL): A Versatile and Portable Solution for Ophthalmic Examinations
The Keeler Portable Slit Lamp (PSL) is an AC-powered biomicroscope designed to facilitate the examination of the anterior and posterior segments of the human eye. This device enables detailed visualization of both front and back structures, including the eyelid, sclera, conjunctiva, iris, natural lens, and cornea. With its advanced features and portability, the PSL is an ideal solution for ophthalmic examinations, particularly useful for elderly, disabled, or young patients.
Versatility and Portability
The PSL combines the ease of use of a desktop slit lamp with portability, making it extremely practical. It is perfect for situations where a conventional slit lamp is not usable. The portability of the PSL makes it an essential tool for clinicians on the go or in various clinical environments.
High-Quality Optics
The PSL offers exceptional optical quality with its multi-coated, multi-element glass optical system. This ensures optimal clarity and maximum performance, allowing for precise and detailed diagnoses of ocular conditions.
Robust and Lightweight Construction
Made with a precision-machined aluminum chassis, the PSL is both lightweight and durable. Its ability to withstand the rigorous conditions of the daily ophthalmic environment makes it a reliable choice for healthcare professionals.
Variable Illumination
The PSL features continuously variable illumination, controllable from zero to maximum. This functionality allows the light intensity to be adjusted according to the specific needs of each examination, ensuring optimal visualization of ocular structures.
Accessories and Fixation
The device is equipped with LED fixation targets, activated by a double click on the trigger, and a 1 mm square aperture for uveitis evaluation. These features facilitate a complete and accurate examination of the eye.
Slit and Filter System
The PSL uses a rotating slit wheel system, offering a slit length of 12 mm and an angle of +/- 60º. The filter options include red-free, blue, neutral density (0.8), and clear, allowing versatile examinations suited to various clinical needs.
Binocular Biomicroscope
The PSL is a portable binocular biomicroscope with convergent optics at 13º. It offers two magnification levels: 10x fixed for the PSL one model, and 10x and 16x with lever change for the PSL Classic model. The working distance of the objective is 100 mm for 10x magnification and 80 mm for 16x magnification, with a field of view of 16 mm and 10.5 mm, respectively.
Dioptric Adjustment and Weight
The eyepieces have a dioptric adjustment of +/- 7 diopters, allowing personalized adaptation for each user. The portable device weighs approximately 900g and measures 238 x 116 x 210 mm, while the charging station weighs 300g and measures 205 x 138 x 40 mm.
Power Supply
The PSL is powered by a switchable mode power unit, compatible with voltages from 110V to 240V. The output is 30VA (12V DC 2.5A), ensuring stable and reliable power.
