Direct Ophthalmoscopes BXα series

Most Accurate Diagnosis

Corrective lens powers range from −36D to +35D in 1D steps. The diopter of the corrective lens is directly indicated even when using auxiliary lenses. The diopter display is illuminated, allowing for clear reading even in a dark room. Furthermore, with the endless rotation of the corrective lens disc, it is possible to smoothly make a wide variety of changes to the correction diopter.

 

Clear Visual Field with the Special Disc

The special disc comprises a small aperture for macular observation, a slit for viewing projections and depressions on the ocular fundus, and a concentric scale and red-free filters for enhancing the contrast of blood vessels.

 

Optimal Balance to Avoid Corneal Reflex

To minimize corneal reflex, polarizing filters are inserted both in the illumination and observation system. By rotating the polarizing filter in the observation system, the angle at which both polarization axes intersect can be changed, allowing optimal observation in which the brightness has been balanced between corneal reflex and the ocular fundus image.

Binocular Indirect Ophthalmoscopes 

Acquiring an Effective Visual Field and Stereovision using an Independent Optical System

A Neitz binocular indirect ophthalmoscope utilizes an optical system in which the spot size, illumination light axis, and observation light axis can each be independently adjusted. This makes the ophthalmoscope well suited for observing the periphery of the ocular fundus. The effective visual field and stereovision provided by this device when observing the periphery of the ocular fundus has garnered high praise from doctors who specialize in vitreoretinal examinations.

 

The Use of Colored LED Bulbs to Reduce Discomfort during Ocular Fundus Observation

To select the LEDs installed in the Neitz binocular indirect ophthalmoscope IO-α LED, we tested all available high-performance, high-quality LEDs in order to select one that could accurately reproduce color closest to that by an electrical light bulb. The ability of IO-α LED to reproduce the color of an electric light bulb has elicited positive responses from doctors who favor our devices. Further, compared to electric-bulb-type ophthalmoscopes, LED-type ophthalmoscopes ensure a clear illumination field with no filament shadow.

 

Eliminates the Hassle of Replacing Bulbs

The service life of an LED is at least 50,000 hours. LEDs eliminate the hassle associated with replacing bulbs, reduce costs, and allow for more worry-free examinations.

Maximizing Continuous Illumination Time

The energy efficiency of LEDs allows for 10 hours of continuous illumination.
