Product Description

The CLA is available in both automated and manual versions. The CLA holds the Lens Positioning Unit (LPU) and lens in alignment with the microscope optical pathway, allowing 360° rotational movement to position the LPU and lens conveniently in the surgical field.
Lens Positioning Unit (LPU)

The LPU is a fine focus assembly that positions the lens above the eye. Its fine focus control wheel ensures precise lens position for crisp focused views. It also has a swing mechanism that moves the LPU and lens into the surgical field or up and out of the way for unobstructed access. Both the LPU and lenses are sterilized components.

Condensing Lens Assembly (CLA)

The CLA includes a Condensing Lens that shifts into and out of the optical pathway when the LPU is correspondingly moved. For corneal views, the LPU is swung out of the surgical field. The automated CLA reads the LPU position and retracts the Condensing Lens out of the optical pathway. When changing to retinal views, the LPU is swung into the surgical field. The automated CLA reads the LPU position and moves the Condensing Lens into alignment with the optical pathway. The manual CLA model moves its Condensing Lens via sterilized handles on a simple manual lever.

REINVERTER (ROLS® )

The new reinverter, ROLS® ∞ has a unique feature to allow precise custom alignment with the microscope to minimize and eliminate image shift and vignetting. It is available in manual and powered versions. The powered version is operated via connection to the automated CLA and synchronized with the LPU position to toggle between inverted and correctly oriented views without removing hands from the instruments. Additionally, it can by operated by footswitch. It may also be switched manually if needed. If purchased together, the automated CLA and ROLS®∞ have a pass through cable allowing the ROLS power supply to also supply the CLA; one power supply for two devices
