The HDL Ergo™ 3.5x uses refractive deflection prisms to redirect the optical axis downward, allowing the surgeon to keep their back straight and head upright while operating. 3.5x magnification, 8.5 cm field of view, and Grade A fine-annealed glass optics. For professionals who want to protect their postural health without giving up optical quality.
The HDL Ergo™ 3.5x is Orascoptic's benchmark ergonomic loupe. Unlike conventional adjustable declination loupes, Ergo technology uses refractive deflection prisms to redirect the optical axis downward without requiring the user to tilt their head. The result is that the surgeon can work with a straight back and neck in a neutral position, even when operating on a low surgical field.
Cervical and back musculoskeletal injuries are one of the main causes of sick leave among surgeons and healthcare professionals. The HDL Ergo™ 3.5x is specifically designed to reduce cumulative postural fatigue during long working days, extending the professional's active working life.
With 3.5x magnification, an 8.5 cm field width, and Grade A fine-annealed glass optics with scratch-resistant and anti-reflective coatings, the HDL Ergo™ 3.5x does not sacrifice optical performance for ergonomics. Working distance and angle are custom configured for each user.
HDL Ergo™ 3.5x prism deflection technology in detail: how it translates into better posture without sacrificing field of view or sharpness.
The HDL Ergo™ 3.5x is for the surgeon who has started to notice cervical or back fatigue, or who wants to prevent postural injuries before they appear.
The deflection prisms redirect the optical axis downward, allowing you to operate with your head upright and your back straight. No need to bend your neck to see the surgical field.
Musculoskeletal injuries are one of the main causes of work limitations among surgeons. The HDL Ergo™ 3.5x reduces accumulated postural strain day after day, protecting long-term health.
3.5x magnification with Grade A fine annealed glass optics and an 8.5 cm field width. Ergonomics does not come at the expense of visual quality.
The deflection prism significantly reduces the neck strain accumulated during long procedures. By the end of the day, the difference is noticeable.
For the surgeon currently working with conventional loupes and looking to make the move to ergonomics, the HDL Ergo™ 3.5x is the market benchmark in its category.
The HDL Ergo™ 3.5x combines 3.5x magnification with deflection prism technology to improve posture. Measurements taken at a working distance of 45.7 cm.
The indicated weight corresponds to the two eyepieces only. Specifications may vary depending on the working distance configured for each user.
