Yes, the ophthalmoscope head is dust-proof, helping to maintain the quality of the optics and prolonging the device's lifespan, which is especially important in busy clinical environments.

Is the device simple to operate?

Answer:

Yes, it features an easy-to-use aperture hand wheel, making it user-friendly for clinicians and reducing examination time, which is beneficial in fast-paced medical settings.

Is the beam path parallel?

Answer:

Yes, the ophthalmoscope head uses a parallel beam path, which helps maintain image clarity and reduces parallax errors, valuable for precise eye examinations.

What type of optics does this ophthalmoscope head use?

Answer:

It uses high-performance optics with an aspherical condenser lens. An aspherical lens reduces reflection and distortion, providing a clearer view even with small pupils. This improves diagnostic accuracy and comfort for both clinician and patient.

Is there a filter wheel included, and what does it do?

Answer:

Yes, it features a filter wheel for all apertures, with a symbol display and the red-free filter. This allows for quick and easy switching between filters, which streamlines the examination process and enhances diagnostic efficiency.

Does this ophthalmoscope head have a red-free filter?

Answer:

Yes, it includes a red-free filter, which enhances contrast by filtering out red light, making it easier to examine blood vessels and retinal structures. This is valuable for detecting certain eye conditions.

What types of aperture shapes are available on this ophthalmoscope head?

Answer:

The aperture hand wheel offers several shapes: semi-circle, small circle, medium circle, large circle, fixation star, and slit. These options give clinicians flexibility to adapt to various examination requirements and patient conditions.

How many corrective lenses are included in the diopter wheel?

Answer:

The diopter wheel features 9 corrective lenses, ranging from +1 to +10, 12, 15, 20, 40 and -1 to -10, 15, 20, 25, 30, 35. This wide range allows for precise focusing and adjustment, which is valuable for examining patients with different vision needs.

What voltage does the ophthalmoscope head operate on?

Answer:

The ophthalmoscope head operates on 3.5 volts (V), which is a standard voltage for medical diagnostic instruments, ensuring consistent performance and compatibility with common power sources.

What type of light does this ophthalmoscope head use?

Answer:

This ophthalmoscope head uses an LED (Light Emitting Diode) powered light, which provides bright, long-lasting illumination and is energy efficient, making it ideal for frequent clinical use and reducing the need for bulb replacements.
