Photonwares’ 4-Head Solid-State UV Light uses high-power UV LEDs as light sources for curing UV adhesives. Major advantages offered compared to traditional lamp-based systems include long life, low power consumption, and compact size. Photonwares’ superior optical design achieves high light coupling efficiency exceeding 85% and uniform light spot intensity.
Each head can be switched on/off either individually by front panel controls or simultaneously by an optional foot switch. The cure time and UV output power can be set independently. Each LED head features an integrated cooling fan.
Questions and Answers
Q: What is the best wavelength I should choose if my epoxies have a wide range of curing wavelengths?
A: All epoxies can be cured at a shorter wavelength since these UV lights are more energetic and provide better and deeper curing. However, not all epoxies can be cured at a longer wavelength that requires a special formulation to be cured thoroughly.
Q: If I want to cure a UV epoxy through a piece of transparent plastic, what wavelength head should I choose?
A: Transparent plastic blocks 365nm UV light. Therefore one needs to choose an epoxy that can be cured at 450nm and choose the matching head.
Q: Is the UV head output power calibrated?
A: The output power of each UV head is tested to meet the range stated on the datasheet. Since the output power of each UV head is highly sensitive to the actual sample position, we recommend customer to calibrate the power density using a power meter in place of the sample. The power can be changed by adjusting the UV head position using our holder or by setting it in the four-head control box.
