In the world of UV LED curing, precision, efficiency, and process control are key. At Clearstone Technologies, we offer two advanced solutions: the ClearSpot and the CA3200. While both systems utilize cutting-edge UV LED technology, their applications and capabilities serve very different needs.
If you’re evaluating which system is best for your process, this guide breaks down the key differences between ClearSpot and CA3200, helping you make an informed decision.
Understanding the Differences: ClearSpot vs. CA3200
| Feature | ClearSpot | CA3200 |
| Primary Function | High-intensity UV spot curing for adhesives, coatings, and targeted applications | Controlled atmosphere UV curing for oxygen-inhibited materials requiring inert gas environments |
| UV Light Source Placement | Liquid light guide for focused spot curing | Bottom-mounted UV LEDs for uniform chamber exposure |
| Wavelength Options | 365 nm, 385 nm, 405 nm (can be emitted simultaneously) | 365 nm, 385 nm, 455 nm |
| Irradiance (Power Output) | 5000+ mW/cm² via light guide for high-intensity, localized curing | 531 mW/cm² across the chamber for uniform area curing |
| Curing Area/Volume | Focused spot size (~0.19 cm²) | 15x15x7.5 cm chamber volume |
| Process Control & Monitoring | Footswitch or manual trigger; real-time LED current monitoring | Automated programmable curing recipes, gas flow control, and pressure regulation |
| Atmosphere Control | No controlled atmosphere; operates in ambient conditions | Sealed chamber with programmable gas flow (Nitrogen, Argon, CO₂) to eliminate oxygen inhibition |
| Typical Applications | Microelectronics, PCB assembly, medical adhesives, optical bonding, 3D printing | Industrial adhesives, coatings, and curing processes that require inert gas environments |
| User Interface & Connectivity | USB & Ethernet for software updates and remote operation | USB-based recipe uploads, process locks, and engineering calibration |
| Cooling System | Passive cooling with liquid light guide | Air-cooled chamber with low-noise fans |
Which System Should You Choose?
Choose the ClearSpot if:
✅ You need high-intensity, targeted UV curing for adhesives, coatings, and bonding applications.
✅ Your process requires a focused UV spot rather than a full-area cure.
✅ You work in microelectronics, medical device manufacturing, optical bonding, or 3D printing.
✅ You want a system that integrates easily into an existing production line with foot-pedal activation and USB/Ethernet connectivity.
Choose the CA3200 if:
✅ Your process requires oxygen-free curing to prevent surface inhibition.
✅ You need uniform, programmable UV exposure for coatings, adhesives, or specialized curing applications.
✅ Your industry relies on controlled atmosphere environments such as industrial adhesives, optics, or coatings requiring inert gas exposure.
✅ You need a sealed curing chamber with integrated gas flow control to improve surface quality and process consistency.
Making the Right Choice for Your Business
Both the ClearSpot and CA3200 offer advanced UV curing solutions, but their use cases and curing methods are very different.
🔹 ClearSpot excels in high-intensity, precision curing—perfect for detailed adhesive and bonding applications where localized UV exposure is required.
🔹 CA3200 is designed for controlled atmosphere curing, ensuring tack-free, oxygen-free finishes for industrial coatings and adhesives.
