Non-Coherent Light Source is used for dermatological applications of photodynarnic therapy. Non-coherent light source eliminates both the high acquisition and operational costs of lasers while delivering the identical light activation required for approved drug protocols. Non-coherent light sources are a course explaining basic physical principles of non-coherent and coherent light emission.

Non-Compliant Balloon is designed to retain the shape as it generates force against the structure. The non-compliant balloon gently dilates the incised areas resulting in plaque compression & vessel wall expansion, with reduced barotrauma.

Non-contact panoramic wide-angle viewing system incorporates the principle of indirect ophthalmoscopy in the operating microscope and enables a view of up to 130 degrees of non-contact fundus observation. Under this system, the eye may be rotated freely so that the extreme periphery can be easily viewed. Even surgery through small pupils is possible.

The non-contact tonometer uses a jet of air to press against the cornea. Photoreceptors in the unit detect when the cornea is flattened a predetermined amount. The amount of time that it takes for applanation to occur is converted by the unit into millimeters of mercury. The longer it takes to applanate the eye, the higher the IOP. It also prevents the spread of contagious eye diseases. It is quite accurate within the normal range.

Non-contact vitrectomy system is designed with a flexible arm for positioning wide angle lenses which easily swings in and out of the surgical field. The clamps attaches to the wrist rest or surgical bed, freeing the surgeon's hands and the assistant to perform tasks other than holding a lens. When used with an upright vitrectomy lens, the system allows the surgeon to work in the vitreous with an upright, non-reversed image under panoramic conditions. It can also hold an indirect lens for use with separate inverter.

Non-depolarising muscle relaxants are drugs that interrupt transmission at the skeletal neuromuscular junction without causing depolarization of the motor end plate. They prevent acetylcholine from triggering muscle contraction and are used as muscle relaxants during electroshock treatments, in convulsive states, and as anesthesia adjuvants.
