Stratum automatically cleans, coats, and cures at the touch of a button. The operator simply loads a pair of lenses, then unloads them at the end of the two-and-a-half minute cycle. If required, Stratum can process one lens even more quickly. On average, Stratum yields 22 pairs of lenses per hour.
	Hands-free operation allows the operator to perform other tasks while lenses are being processed.
	A built-in display and easy-to-use keyboard make training fast and effortless.
	Sophisticated sensors and diagnostics constantly monitor unit performance. Intelligent software displays machine status and prompts operators for necessary preventive maintenance routines.
	Fluid sensors automatically prompt operators to replenish cleaning fluids and coatings.
	State-of-the-art ultra violet (UV) technology provides predictable and economical bulb life.
	A user interface prompts the operator in English, Spanish, or French.

Integrated Cleaning, Coating, and Curing

Once the lenses are loaded into the carousel, high pressure de-ionized or distilled water cleans them of contaminants. The solventless coating is then applied, and the lenses move into the UV curing phase. Stratum's innovative method of holding lenses successfully cures thin centered lenses without warping. And, since curing is integrated into the entire process, operator exposure to UV light or chemicals is eliminated.

As a self-contained system, Stratum can be located in a normal laboratory environment without the need for a clean room. Internal positive air pressure assists in keeping environmental dust and dirt out of the unit. Plus, a built-in filtration system removes airborne contaminants to ensure exceptional coating results.

Coating Technology

Stratum applies one coating that is appropriate for all plastic lenses. Stratum 2D offers laboratories the flexibility to dispense either a highly tintable coating or a super-hard, non-tintable coating – from the same machine. 

	Stratum's high performance, UV-curable coatings are the result of joint development efforts between Gerber Coburn and Lens Technology, the world's leading manufacturer of ophthalmic coatings.
	Because the coatings contain no hazardous or flammable solvents, there is no offensive odor. Any odors that might be produced during cleaning and curing are virtually eliminated via Stratum's special filtering system.
	Cleaning and coating processes do not require the use of isopropyl alcohol.
	Coating over-spray is collected in disposable trays and automatically cured into a solid state that is environmentally safe for disposal.
