Required Utilities
The following facility utilities are required to operate the Mini2. The provisions for these facilities
are the responsibility of the customer and are not included in the scope of supply for this
machine.
Physical Location
The machine should be installed in a location that is accessible
for easy disconnect of power and has good ventilation with an
air exchange of 4-5 times per hour. It should be located in a low
traffic area to minimize possible dust contamination. While it is
not necessary to install the Mini2 in a clean room, it is not a
good idea to place it near a lens edger either.

System Overview
General Overview
The Mini2 is a robust backside hard coating machine that performs all of the required operations
within a single machine. The core coating functions utilize the same technology as the highly-
touted MR3 coating system. These key processes are arranged and packaged in a way to
reduce cost for today’s small to medium sized labs.
The Mini2 is a completely self-contained system that is not required to be installed/operated in a
cleanroom environment. The system utilizes a pre-filter and HEPA filter to maintain a
continuous positive pressure of extremely clean air, which reduces the dependability on
operating in a clean environment.
Wash process
The lens is washed with high pressure,
deionized water. The clean deionized water is
stored in a reservoir (supplied by UOC) which
should be placed on a shelf below the machine.
When a wash cycle starts, clean water is drawn
through a filter (located inside the reservoir) and
out of the reservoir, into the pneumatically
driven pump. The pump increases the pressure
of the water to 2,000 psig. The high pressure
water is then sprayed through a nozzle onto the
back-side of the lens. The lens is spinning
during the wash process to help assure a
complete surface cleaning. The spent water is
collected in the bottom of the wash bowl and drained into a waste water reservoir which should
be placed on a shelf below the machine. At the end of the wash cycle, the water pump stops,
and any residual water downstream of the pump is emptied through the dump valve into the
clean water reservoir.
The system PLC monitors all system sequencing to control the water pump and solenoid valves.
Dry process
After the wash process is complete, the machine will initiate the drying process. The lens is
dried by use of compressed air. In the drying process the air nozzle is articulated in a manner
that ensures a complete drying of the entire lens surface. Similar to the wash process, the lens
is spun while in the drying station to help remove all of the water.
As shown in Figure 4 below, the air that is used for drying the lens passes through several
filtration and drying stages to obtain the clear and dry air that is used for the drying process.
The timing of the drying process is controlled by the system PLC.
Figure 3 - Wash system schematic

www.ultraoptics.com page 5
Figure 4 - Drying system schematic
Coating application
After the lens is washed and dried, the arm and spindle assembly will lift and swing over to the
coating application station. With the lens down in the coating application station, the coating
pump draws coating material from the reservoir and pumps it through a filter, up to the surface
of the lens. The lens is being spun during the time of application to ensure a sufficient amount
of coating is applied to the entire surface. After the coating has been applied, the pump will stop
and the spin speed of the lens changes to a new value which will generate the proper film
thickness of coating, based upon the specific coating being used. The timing and spin speeds
are controlled by the system PLC. This process is shown schematically in the following
diagram.
Figure 5 - Coating system schematic

www.ultraoptics.com page 6
Cure process
The Mini2 is designed to cure Ultra Optics’ line of UV-based coatings. After the lens has
completed the coating application cycle, the lift cylinder will raise the arm assembly. The user
will then carefully grab the lens by the edge and flipping the switch to UNCHUCK to release the
lens from the suction cup. It is recommended to keep the coated surface facing down to reduce
the risk of airborne contaminants settling onto the wet surface.
An ultra-violet lamp resides in the curing station. The radiation energy from this lamp is used to
effectively cure the coating to the lens with the proper characteristics of adhesion, hardness,
etc.
System Operation
Start-up Procedure
The following procedure should be followed upon machine start-up.
1. Inspect the machine to be sure nothing is in it that would impede the movement of the
swing arm spindle assembly.
2. Turn air supply on.
3. Fill clean/wash water reservoir with deionized water and empty the waste water reservoir
4. Turn machine power on with red switch.
5. Check coating level and coating height.
6. Run test to be sure the lens is getting completely dry.
Coating Machine Operation Procedure
The following procedure should be followed to coat a lens.
1. Inspect the machine to be sure nothing is in it that would impede the movement of the
swing arm spindle assembly
2. Turn air supply on
3. Turn UV Cure machine on using the main power switch located on the back of the unit.
a. Wait ten minutes for the light to reach its full intensity!
4. Hold the lens in a gloved hand with the backside facing up. Apply a dime-sized amount
of Ultra Optics ClearView lens cleaner, or IPA, to the backside surface. Using a gloved
finger, rub the lens cleaner all over the surface to break-up any dirt, polish residue, oil,
etc.
5. Place lens, convex side up, centered on the vacuum chuck and flip the switch up to the
CHUCK position. Let go of lens and make sure it does not fall off the vacuum cup.
6. Press the green CYCLE START button. The machine will now automatically wash and
coat the lens.

blink.

www.ultraoptics.com page 7
7. Remove the lens by carefully holding onto edges and flipping the switch down to the
UNCHUCK position.
a. It is recommended to keep the coated surface facing down to reduce the risk of
airborne contaminants from getting on the freshly coated surface.
8. With the lens removed from the machine, this is a good time to do a quick visual
inspection of the quality of the coating film. If there are any issues found, it is possible to
clean the wet coating off with soap and water, then re-coat the lens.
9. Take the coated lens to the UV Cure unit. Flip the VACUUM switch up.
10. Open the door and center the lens, front side up, on the vacuum cup.
11. Close the door and press the START button.
12. When the lens returns to the front of the cure unit, open the door, grab the lens and flip
the VACUUM switch down to release the lens.
a. If there is a small amount of uncured coating on the front side of the lens, wipe it
off with a non-abrasive cloth.
NOTE: The Mini2 and Cure Unit are designed with suction cups that work for nearly all lens
types. If a particular lens type is not working well, contact Ultra Optics for other suction cup
designs.
The lamp in the UV Cure Unit is designed to last approximately 1,000 hours. If the lamp is
used past 1,000 hours, the coating will likely not be properly cured. Be sure to note that
the hour meter display has a blinking decimal point. When the meter reads 1,000.0 hours
(as detected on the hour meter), call Ultra Optics to order a replacement light module.
When you receive the replacement module, return the original unit for a core credit.
