The HDL™ 4.5x takes prismatic magnification to the next level: 4.5x magnification with an expanded 7.50 cm field of view that preserves peripheral visibility where other high-magnification loupes sacrifice it. Designed for professionals operating on small anatomical structures who need maximum resolution without losing surgical context.
The HDL™ 4.5x is the prismatic loupe of choice for surgeons working on highly technical procedures where fine-detail resolution is critical. With 4.5x magnification and an expanded 7.50 cm field of view — significantly larger than that of conventional loupes with the same power — it enables precise work without losing orientation in the surgical field.
Its expanded-field prismatic technology brings the operative site closer and into focus with the edge-to-edge clarity that has defined Orascoptic's HDL line. The anti-reflective coating on the objective lens increases light transmission, producing a brighter, higher-contrast image, especially useful in cavities with challenging lighting.
All optical systems are manufactured with fine-annealed Grade A glass lenses featuring scratch-resistant and anti-reflective coatings. The carrier lenses are made of high-index polycarbonate. Available in TTL and flip-up versions, in all frames of the Orascoptic system, with working distance and declination angle custom configured.
The HDL™ 4.5x in detail: expanded-field prismatic technology for procedures where every micron counts.
The HDL™ 4.5x is designed for the experienced surgeon performing highly complex procedures where standard magnification is no longer enough.
4.5x magnification for working on small-caliber vessels, nerves, and tissues with the precision required by the most demanding procedures.
7.50 cm field width at 4.5x — a real advantage over conventional loupes of the same power that sacrifice field size for magnification.
The anti-reflective coating on the objective lens allows greater light transmission, producing a sharper image with better contrast in cavities with difficult lighting.
The HDL™ 4.5x is not a first pair of loupes. It is the natural choice for professionals who are proficient in working with magnification and want to move up to greater detail without compromising ergonomics.
For the surgeon who already works with 3.5x loupes and feels they need more resolution in certain procedures, the HDL™ 4.5x is the next natural step: greater detail without changing system or frame.
With a 7.50 cm field of view at 4.5x, the HDL™ 4.5x offers a wider visual field than any conventional loupe of the same power. Measurements taken at a 45.7 cm working distance.
The specifications provided are approximate and may vary depending on individual factors, such as each user's specific working distance.
The higher the magnification, the more important frame stability becomes. Choose the one that best suits your surgical workflow.
