COBRA

The new generation of compact lasers - Nd:YAG and SLT combined in one device

Two absolutely independent lasers – combined in a space-saving, ergonomic unit. SLT and Nd:YAG-Laser are indispensable in modern ophthalmology practice.

Brilliant optics

Reliable laser for the anterior segment of the eye

Specially tempered optics with high resolution for a detailed view into the anterior segment of the eye.

Optionally available with convergent or parallel lens barrel. Simply see clearer: The integrated neutral color filter protects you from unwanted laser reflections.

Do you need a YAG and a SLT laser?

A.R.C. Laser is leading in laser ophthalmology and offers a comfortable system with COBRA for you:

Customized for the anterior segment of the eye
Two modern lasers in one unit
Sufficient space under the treatment table, also for patients with wheelchair
Wheelchair-friendly 2-column-design

Electronic level control up to 920 mm via two height-adjustable motor columns
The compact system consisting of laser, table and slit lamp optionally with rollers
µ-chip SLT
Homogeneous spot
No wear-out effects and without energy loss over the entire life cycle

COBRA – Fastest repetition frequency worldwide

Other SLT systems are based on flash lamp technology. The resulting active beam depends on charging cycles of the capacitors, which is why they are so slow. The modern µ-chip SLT from A.R.C. on the other hand convinces by:

Quick pulse sequences
Perfect stain quality
Temperature stability

SLT laser:

Quick Refresh ~10Hz Rep-Rate
TouchScreen

Nd:YAG Laser:

Precise spot
worldwide smallest focus spot
