HistoryThe Laser 2000 Ophthalmic started in the year 2000. Mean-while MC-Flexc is a widely industry-proven laser system. Our laser engraving and printing systems are operated suc-cessfully by more than 50 companies worldwide. Other than ophthalmic, Laser 2000 also has reference customers in auto-motive and semiconductor industries as well as in numerous research institutes and facilities.

Laser 2000 looks back on some 20 years of laser experience in the field of material processing. There are more than 100 em-ployees in production, sales, and service. In 2007, the turnaround surpassed 35 million in Europe. We have an open structure. Cus-tomers are welcome to see the entire company and meet with our R&D, CAD, service, and production departments.

Laser 2000 is committed to providing service for our custo-mers for a long time to come.

ServiceFor any industrial application it is imperative to operate high-ly reliable equipment and to secure timely service. For this purpose, Laser 2000 continues to enhance machine quali-ty standards and to add service engineers as the number of customers and machines sold grow. Today, there are service facilities located close to our customers in Europe, America and Asia.

Eight years ago Laser 2000 developed the first Galvanometer controlled Excimer Engraving Systems for the Ophthalmic in-dustry. In the course of the years, the product mix has been extended by CO2 engraving systems, Inkjet Printing machines

and equipment for quality test and logistics. The Laser 2000 product range for RX labs and lens mass production is em-phasized and coloured in the adjoining marginal drawing.

MC-Flexo CO2 Engraving Systems

Common descriptionThree different Ophthalmic engraving CO2 systems (MC-Flexo C3.0; C4.0; C5.0) are determinated for manual or automatic loa-ding as well as for engraving of blocked and unblocked free form lenses. The systems are based on experience in CO2 laser systems and various patents for fast and accurate laser positio-ning and low heat insertion into the material. This is essential for marking ophthalmic plastic lenses in high quality.

The quoted laser systems contain all components, materials, hard- and software for “dotted engraving code” and “vector engraving”. It is important to mention that the control soft-ware already has the “One Click Import” functionality for vec-tor and pixel graphics.

MC-Flexc High-End Laser Engraving Systems

Laser 2000 has developed the MC-Flexc laser engraving sys-tem combining precise mask projection with a high-speed galvanometer laser beam scanning system. This permits the engraving of an unlimited mix of characters, patterns or codes without changing the lens aperture. This is achieved by replacing the usual lens with a specially designed image objective.

The method is very fast – allowing the use of full pulse speed of an Excimer laser – and far more economical since a greater part of the laser energy can be applied. Conventional methods are less flexible because there each character change also re-quires an aperture change. The systems also need more pow-erful and thus more expensive laser systems.

With the MC-Flexc High-End Laser Engraving Systems of La-ser 2000, the characters to be engraved are simply generated as a chain of x-y coordinates in a text file such that every user can easily create and apply his own character set.

By appropriate selection of laser parameters text heights can be miniaturized to approx. 20 µm. The contrast and appea-rance of the engraving remains freely selectable. Meanwhile, the patented MC-Flexc system became international standard in the ophthalmic industry. It can be used in all situations where conventional laser products fail to operate due to micro cracks or unclean marking results.

MC-Jet Inkjet Printing Systems

Common descriptionIn the ophthalmic industry, the market of progressive lenses for near and far sight is the market of growth. Usually, these lenses are pad-printed to identify work-in-process lenses as well as final products. This is done to ease the work of opticians fin-ding semi- or quasi invisible laser engravings, which indicate the properties of the lens.

Until recently however, lens manufacturers had to live with the pad printing machines’ major flaw of inflexibility. Now, the new Inkjet Printing systems provides great flexibility and gives the lens manufacturer great market advantage. The MC-Jet re-places limited pad changers. Different images on the lenses are now simply placed by software. Consequently, yearly running costs are greatly reduced. With the special MC-Jet different lens geometries may follow in a mixed sequence. The convex

or concave lens geometry can either be determined by the MC-Jet or a fully automated version – be retrieved from barcode and host computer. As an additional feature, the MC-Jet also gives the opportunity to freely import any graphical data. This way, lenses and molds can also be printed with individual com-pany names and logos.

The MC-Jet will become the flexible alternative to pad printing processes mostly because it is more flexible and no pads are needed. Finished lenses or molds can be marked with individu-al information for personalized products.

The MC-Jet lets you enjoy the higher flexibility – but it is also far more economic regarding the cost of investment, yearly costs, and cost per lens.

Quality and Inspection

Mapping device for full lens inspection MQ-Jet V2.2 - the flexible adaptation to the fast-moving mar-ket developments. The seamless integration of additional functions including optical power mapping of lenses, incre-ases the system's throughput and overall productivity.

The classic methods for optical measurement in RX pro-cesses are systems for dioptre measurement for single vision or free form lenses. In most cases these systems are supple-mented by pad printing solutions for adding the information necessary for the optician. Nevertheless the downsides of the well known pad printing technology are its limited flexibility, high costs for clichés and high maintenance. Currently, opti-cal measurements of lenses using this equipment are limited to discrete positions on the lens, so there is no possibility to make a complete evaluation of a free form lens.

New generation of control system

The MQ-Jet V2.2 represents a new generation of measurement and control system combining Inkjet Printing with automatic lens mapping over the entire surface. This totally non-contact approach captures and records vital data such as optical power, cylinder and prism values, instantaneously. The intuitive soft-

ware allows the user to interrogate the power measurements at every point of the surface, using the XY coordinates and the diameter around these coordinates. Furthermore, the customer can define near and far field size of the measuring area, and the number of measuring areas for every lens.

Complete quality assessment

The MQ-Jet V2.2 accepts all lens types from single vision lenses with a central measurement point to progressive lenses with near and far field. Even special lenses with more than two fields of view (e.g. special glasses for pilots) can accommodated. In addition, the actual measurement values can be compared with the model data of the lens. Tolerance limits and levels can be set such that devia-tions from the optimal values of the lens will be shown in different colours e.g. green, red, yellow, for a quick visual comparison.

After mapping, the optical parameters of a free form lens can be detected. Only with these steps it is possible to make a com-plete quality assessment with the decision whether the lens fulfils the high quality standards of the manufacturer or not. The exchange of data accomplished via OMA interface. Custo-mer-specific solutions are available that include a connection to an SQL data base to ensure statistical process control.
