- Dust-proofThe ri-scope L opens a new era of high-performance and user-friendly diagnostic instruments for E.N.T and Ophthalmology. Li-ion/LED technology used in these new high-performance instruments significantly reduce costs while improving both effectiveness and reliability.

The lightweight lithium-ion battery used in the ri-scope L has an unsurpassed lifetime -  with higher loading capacity and sustained high-power performance, even after well over 1000 charge cycles.

A nearly unlimited lifetime with the highest luminosity are the benefits of the LED technology used with the ri-scope L. The lamp inside never gets hot, provides true-colour, even illumination of the area under examination and is guaranteed never to fail.
