gerber coburn: Advanced Lens Processing System

The DTL lens generator works with the MAAT sub-aperture polisher
or traditional finers and polishers.

The Advanced Lens Processing System (ALPS) is the latest addition to Gerber Coburn's Performance Series line.

This Industrial-strength system produces high quality traditional (sphere and toric) and backside complex lens curves in plastic, high-index and polycarbonate materials.

Designed as a platform that can be easily expanded and fully automated to grow along with your lab, Alps has two main components: the Diamond Turning Lathe (DTL) dry-cut lens generator and the Multi-Axis Adaptive Technology (MAAT) sub-aperture polisher.

In one complete system, ALPS offers every option for processing all lens prescriptions:

High-speed traditional fining and polishing

Cut-to-Polish lens processing with a choice of conventional or sub-aperture polishing

Digital (free-form) lens processing

Alps equips your lab to produce standard as well as premium branded lens designs. Advanced lens processing, which combines cut-to-polish or digital surfacing with sub-aperture polishing, involves fewer steps and less equipment for your lab.

Cut-to-Polish processing eliminates fining, saving time plus the expense of fining equipment and consumables. Digital surfacing makes it possible to process the front, back or both sides of any optical lens blank.

Sub-aperture polishing after either cut-to polish or digital lens processing yields extremely smooth lens surfaces. It is essential to free-form lens production, clarifying digital lenses without altering the complex lens curves.

Compared with conventional methods, cut-to-polish and digital lens processing with sub-aperture polishing are more economical. There are no fining or polishing pads to buy or handle, and traditional hard tools are less likely to be needed. ALPS's computer-controlled functions eliminates most lens handling, so labor costs and lens breakage are dramatically reduced-and visual quality is consistently excellent.

ALPS boosts your lab's productivity, speeding up traditional processing and taking production to the next level with advanced lens processing.


Alps is a modular system that makes it simple for your lab to purchase units with automation or later for maximum productivity. DTL and MAAT are available with automated lens pick-and-place mechanisms that minimize lens handling, reducing lens breakage and labor costs. MAAT's automated lap management system selects the correct laps for each lens, streamlining the process and increasing production yields.

The Diamond Turning Lathe (DTL) generator is the heart of the Advanced Lens Processing System. This high-speed, dry-cut, single-point lens generator offers your lab many advantages that are not possible with conventional lens generating technology.

	Ease of use
	Extremely smooth lens surfaces
	High-speed traditional, cut-to polish and digital lens processing
	Reduces lens spoilage
	Lowers lens production costs

Whether you process twenty-five, five hundred, or one thousand or more jobs per day, the DTL lens generator offers maximum performance at an affordable price. The user interface, diamond machining technology and swarf management systems promote throughput gains.

Purchased as a manual or automated unit, the DTL's expandable platform generator can be used:

	With traditional finers and polishers for high-speed lens processing, or
	Paired with MAAT for a complete cut-to-polish and digital lens processing system.

If you already own the DTL100, a simple conversion kit can upgrade the unit to add cut-to-polish and free-form lens surfacing capabilities.

The X-axis (background) is used for all the roughing passes to quickly remove large amounts of lens material. The V-axis (foreground) is designed for a final pass surface quality.

Using dry-cut generating technology means no more water filtration systems for lens waste removal, water treatment chemicals or coolants. The swarf management system keeps your lab environment clean by containing lens debris in the chamber until it is evacuated. Airflow through the cutting/swarf chamber cools the cutter and evacuates debris for easy disposal.

The DTL user interface system consists of a large touch screen with large buttons, clear labeling and Window-like programming, making it easy for operators to enter, display or change job information.

The manual DTL simplifies loading and unloading blocked lenses by an operator. The automated DTL keeps job information and trays moving in sync from start to finish.

The MAAT sub-aperture polisher is designed specifically to work seamlessly with the DTL generator series. Following the exact tool path used during lens generating, the MAAT produces a more accurate lens surface.

MAAT replaces traditional fining and polishing processes, offering your lab the advantages of sub-aperture polishing.

	Digital production of progressive lenses and other complex lens designs.
	Less labor, no fining consumables and lower production cost per lens
	Reduces semi-finished progressive lens inventory
	Eliminates hard-tool lap inventory, storage and management

MAAT's multi-axis design tilts the lens precisely in order to keep the polishing tool perpendicular to the area being polished, while accurately controlling pressure so that material is removed evenly throughout the entire surface of the lens.

The high-speed spindle and sealed polishing chamber expedites lens material removal, resulting in a high quality, uniformly polished lens in less time than conventional fining and polishing methods.

While traditional hard-tool lens polishing is messy, MAAT has a sealed polishing chamber to help keep the laboratory clean. An automatic lens washer/dryer is built into every manual and automated MAAT.

Now your lab can say goodbye to the tedious, time-consuming process of traditional hard tool polishing. With the MAAT sub-aperture polisher, there's:

	NO picking among thousands of laps
	NO peeling and unpeeling fining and polishing pads
	No washing laps
	NO restocking laps
	NO re-truing laps
	NO roomfuls of lap racks and inventory

Maat automatically selects, places, removes and keeps track of the correct sub aperture lap to match the lens being processed. Instead of many different hard laps for polishing, MAAT uses a small number of Gerber Coburn's Variable Lap Tools (VLT).

MAAT's RFID technology pairs a reader with a chip built into the VLT for instant feedback about the lap and lens about to be processed. This prevents lens breakage and keeps jobs moving through your lab. The RFID chip also measures the amount of usage of the lap, and the system automatically discards the lap when it has been fully consumed. Both the manual and automated MAAT units feature this intelligent lap management system.

VLTs with RFID technology replace thousands of hard-tool laps.

VLTs allow you to reclaim valuable storage space in your lab for other activities.
