Uvitron SunSpot 2 - High-power UV Spot Light Curing System

Product Summary

The SunSpot 2 is a next generation high intensity ultra-compact light curing system, and the industry’s price/performance leader. The unit was designed with low cost of ownership in mind, with its long-life UV/visible arc lamp, and filtered input long-life light guide. The SunSpot features easy to use exposure time controls and foot pedal activation. The system weighs a mere 6 pounds, and its 10.5 x 8.6 x 4 inch size is the smallest in its class.

Highest Output intensity

The Sunspot’s new 200W lamp delivers the highest intensity in the industry. With its 18+ W/cm2 UVA and > 30W/cm2 output from 300 to 550 nm, the system will maximize curing speed, and is compatible with high speed production automation equipment. This high intensity also makes the SunSpot 2 ideal for use with multi-pole light guides for simultaneous light delivery to 2, 3 or 4 curing zones, eliminating the need for multiple lamp systems.

Cool Light Output

The unit features a dichroic coated reflector, which reflects only the useable UV wavelengths of light through the light guide. The harmful high temperature infrared is diverted away from the material being cured. A secondary in-line filter is utilized to even further reduce heat for extremely sensitive applications.

Timer-Controlled Shutter

The system features and accurate 99 second, foot pedal initiated exposure timer and shutter, that frees the operators hands for other tasks. At any time, a second press of the pedal will immediately stop the exposure and close the shutter. The timer can also be switched from timed to manual mode for operator control of curing duration, with the shutter remaining open only while the pedal is depressed.

Convenient Front Panel Indicators

A lamp Ignited indicator illuminates when the lamp is lit, and a lamp ready LED signals when warm-up is complete. A resettable front panel hour meter tracks lamp age, allowing for consistent lamp replacement scheduling.

Lamp Intensity Control

The SunSpot 2 has a user adjustable front panel locking intensity control, with a 35 to 100% combined power adjustment range. This feature provides the flexibility of choosing appropriate curing intensity for sensitive materials, and for regulating intensity at a given level as the lamp ages.

Light Guide Handle Lock

The light guide receptacle includes a handle locking thumbscrew that prevents accidental guide pull-out, and provides for easy multi-pole guide balancing.

External Logic Signal Interface

The system can be remotely monitored and controlled using logic signals available at a 9 pin D-sub connector on the unit’s rear panel. The digital logic functions allow high speed control of the SunSpot for applications requiring a direct interface with machine controllers or PLCs. Control signals include lamp off, shutter open, and hour meter reset. Monitoring signals include lamp ignited and lamp ready.

Lamp Power Regulation

The SunSpot’s switch mode power supply maintains constant lamp power regardless of variations in AC line input or lamp voltages. This tight regulation results in stable light output, repeatable cure times, and long lamp life.

Lamp Auto-Dim

The system automatically reduces lamp power to a low standby level when the shutter closes, instantly returning to full intensity when the shutter re-opens. This auto dimming extends lamp life and reduces power consumption and unnecessary heating.

Best-in-Class Lamp Life

The SunSpot systems now have enhanced lamp life of greater than 2000 hours, significantly lowering operating and maintenance costs.

Quick-Change Lamp

The system's side lamp access panel is easily removed by loosening thumbscrews, making the lamp/reflector module replacement possible in as little as 1 minute.

Optional Lamp Spectrums

The SunSpot 2 is available with either UVA or UVB enhanced spectrum lamps, ensuring compatibility with all adhesives, coatings, inks and paints from all manufacturers.

Safety Interlocks

The unit features two unique safety interlocks, for maximum protection during operation and maintenance procedures. The 1st interlock automatically forces the shutter closed if the light guide is removed, preventing operator exposure to high intensity light. The 2nd interlock immediately removes system AC input power when the lamp access panel is opened, protecting the operator from high voltages or high intensity light present behind the panel.

Forced Air Cooling

The infrared regulated dual fan cooling system directs air to critical system components, ensuring cool operation, maximum lamp life and system reliability.

Two Input Voltage Range Options Available

The unit is available in a 90 to 132VAC or 180 to 265VAC input ranges, ensuring compatibility with power sources world-wide.

High Transmission Light Guide Included

The system ships complete with a high output long life 5mm x 1m liquid light guide. Many other types and lengths are also available upon request (see accessories table below).

Light Guide Part Numbers

Liquid Light Guides (Single Pole)
UV0570* Liquid Light Guide, 1m x 5mm Liquid filled light guides have higher transmission for UVA wavelengths and cost significantly less than fiber equivalents. The tradeoff is that the liquid guides do not have as long life, especially for longer exposure times or when used for shorter wavelengths (i.e. UVB, UVC). Deep UV liquid guides with longer life for UVB are also available for slightly higher costs.
UV0571* Liquid Light Guide, 1.5m x 5mm
UV0572* Liquid Light Guide, 2m x 5mm
UV0774 Liquid Light Guide, 1m x 8mm
UV0775 Liquid Light Guide, 1.5m x 8mm
UV0776 Liquid Light Guide, 2m x 8mm
UV1195 Liquid Light Guide, 3m x 8mm
UV3381* Liquid Light Guide, Deep UV, 1m x 5mm
UV1508* Liquid Light Guide, Deep UV, 1.5m x 5mm
Fiber Light Guides (Single Pole)
UV0765 Fiber Light Guide, 1m x 5mm Fiber guides do not degrade with exposure over time, and are best for high power and long UV light exposure times. However, their transmission is lower and cost is typically higher than for liquid filled guides.
UV0766 Fiber Light Guide, 1.5m x 5mm
UV0767 Fiber Light Guide, 2m x 5mm
UV0768 Fiber Light Guide, 1m x 8mm
UV0769 Fiber Light Guide, 1.5m x 8mm
UV0770 Fiber Light Guide, 2m x 8mm
Multi-pole Light Guides
UV2168* 2 Pole Liquid Light Guide, 1m, 5mm Common End Multi-pole light guides are used for applications that require the light to be split and delivered to multiple cure targets. Liquid types have higher transmission, have well balanced light output between legs and provide the best value. However, they can degrade with exposure over time. Fiber guides are also well suited for this purpose since they also ensure equal delivery of light regardless of guide rotation. Fiber guides are best suited for high power and long light exposures and do not degrade over time.
