Description
The Stereo Optical 8400 Acuity and Astigmatism Projector Slide is a professional diagnostic accessory designed for ophthalmic and optometric visual examinations.
This multipurpose slide combines several common testing targets in a single format, including letter-acuity charts, number-acuity charts, tumbling “E” optotypes and an astigmatic clock. This selection allows the eye-care professional to perform different visual-acuity assessments and support the evaluation of astigmatic conditions without repeatedly changing slides.
Stereo Optical projector slides are printed on selected high-quality transparent photographic film. The printed film is sealed between two sheets of optically clear glass to protect the test image, maintain the integrity of the optotypes and provide consistent projection during repeated clinical use.
The 8400 slide is compatible with A.O., Reichert, Marco and Woodlyn vision projectors. It is suitable for professional use in optometry and ophthalmology practices, vision clinics and other environments equipped for projected visual testing.
