Uvitron SunSpot SM - Mid-power UV Spot Light Curing System

Product Summary

The SunSpot SM is a high intensity compact light curing system. The unit was designed with low cost of ownership in mind, with its vertically mounted long-life mercury lamp, separately replaceable elliptical reflector, and filtered input long-life light guide. The Sunspot’s easy to use exposure time controls and foot pedal activation make operating the unit a snap. The system weighs in at less than 7.5 pounds, and its 10 x 5 inch footprint is the smallest in its class.

Note: The SunSpot SM is a legacy product - For new customers, take a look at our updated SunSpot 2 spot curing system.

Highest Output intensity

The Sunspot's 100W lamp delivers the highest UVA intensity per lamp watts in the industry. This means that with its >10W/cm2 output, the system will maximize curing speed without overheating the material being cured.

Cool Light Output

The unit features a dichroic coated mirror, which reflescts 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. Competitors' units in this high intensity class use only in-line filters, which when used alone are not as effective. Inadequate filtering could result in overheating of the object being cured, and damage of the adhesive bond line.

Long Lamp Life

The SunSpot's unique design features provide exceptional lamp life:

  • The lamp is mounted vertically, which allows the arc to fall straight inline with gravity. This prevents the arc from wandering into the quartz envelope and overheating it. This scheme also ensures the arc strikes the conical anode equi-radially, preventing uneven electrode erosion.
  • The lamp is constructed with an extra-heavy blunt tipped anode electrode, which does not degrade quickly over time (like the needle shaped electrodes of traditional arc lamps).
  • Airflow is carefully channeled to provide symmetrical cooling of the lamp, which ensures long end seal life, and prevents damaging hot spots and arc sputtering.

Lamp Power Regulation

The system’s patented Power-Plus Lamp Driver maintains constant lamp power regardless of variations in AC line input or lamp voltages. This regulation provides for stable light output, repeatable curing times, and longer lamp life.

Wide-Range AC Line Input

The Wide Range 90 to 265 VAC line input makes the SunSpot easy to use in any country, with no wiring changes or voltage select switching required.

Timer-Controlled Shutter

The unit features and accurate 1 to 99 second, pedal controlled exposure timer and shutter. The timer can be switched from timed to manual for operator control of curing duration.

Convenient Front Panel Indicators

A front panel hour meter tracks lamp age, allowing for consistent lamp replacement scheduling, and a Lamp Ready LED notifies the user when warm-up is complete.

Quick-Change Lamp

The system's side lamp access panel is removed by loosening a single thumbscrew, making lamp or reflector changes possible in 1 to 2 minutes.

Forced Air Cooling

The quiet dual fan cooling system directs air to critical system components, ensuring cool operation and high system reliability.

Safety Interlocks

The SunSpot 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 removed or not fully closed, protecting the operator from being exposed to high voltages or high intensity light which is present behind the panel.

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.
