3nethra Ultima, Non-mydriatic Fundus Camera

3nethra Ultima is a compact, multifunctional digital fundus imaging system designed to deliver high-resolution retinal and anterior-segment imaging with advanced AI-powered analysis. With a 20 MP imaging sensor, support for both mydriatic and non-mydriatic imaging, and integrated clinical analysis capabilities, it provides a versatile solution for modern ophthalmic practices.

Its advanced capabilities extend beyond retinal imaging to include non-contact dry eye and corneal assessment, making 3nethra Ultima a comprehensive platform for efficient ocular screening and diagnostic evaluation.

Capture highly detailed images of the retina and anterior segment with a 20-megapixel CMOS sensor for enhanced visualization and clinical assessment. 

Provides the flexibility to perform retinal imaging with or without pupil dilation, supporting diverse clinical workflows and patient requirements. 

A standard 45° field of view can be expanded to 75° through montage, enabling broader retinal assessment and visualization of peripheral regions. The system also supports 105° montage with internal fixation according to the manufacturer's specifications.

High Dynamic Range imaging enhances visualization of fine retinal details, including areas around the optic disc and peripheral retina.

The optional Dry Eye Diagnostic Module enables non-contact ocular surface assessment, including:

• Tear Break-Up Time (TBUT)
• Lipid Layer Interferometry (LLI)
• Tear Meniscus Height (TMH)
• Meibomian Gland Dysfunction (MGD)
• Fluorescein Imaging
• Demodex assessment
• Pink Eye / Conjunctivitis assessment

Integration with FH-POISE™ provides AI-driven analysis supporting assessment of retinal, corneal, and dry-eye conditions. The platform is designed to assist with screening for conditions including Diabetic Retinopathy, Glaucoma, ARMD and Cataract, among others.

Auto-focus and intelligent imaging algorithms help simplify image acquisition, reduce operator effort, and support efficient clinical workflows.

The integrated 9-point internal fixation system helps maintain consistent patient alignment and facilitates imaging of different retinal regions.

Compatibility with FH TeleCare and telemedicine platforms enables remote screening, image sharing, and teleophthalmology workflows—particularly valuable for outreach and remote eye-care programs.
