Welcome to Crystal Medical.

Candela lasers are known for their precision, reliability, and effectiveness across various applications, particularly in dermatology and aesthetic medicine. The different models of Candela lasers, such as the GentleLase, GentleMax, and GentleYAG, share common components but also have model-specific parts tailored to their specialized functions. Below is an overview of the key parts across various Candela laser models:

1. Laser Head (Laser Module)

  • GentleLase: Uses an Alexandrite laser (755 nm) ideal for hair removal and pigmented lesion treatments.
  • GentleMax: Combines both Alexandrite and Nd:YAG lasers, offering dual-wavelength capabilities for versatile treatments.
  • GentleYAG: Features a Nd:YAG laser (1064 nm), effective for treating deeper skin issues and vascular lesions.

2. Delivery System

  • Optical Fiber: Transmits the laser energy from the laser head to the handpiece. Candela uses high-quality optical fibers that are designed to maintain energy transmission with minimal loss.
  • Handpiece: Ergonomically designed to provide comfort during treatment, the handpiece delivers the laser energy to the treatment site. The handpiece is model-specific, with different spot sizes available for various treatment areas and purposes.

3. Dynamic Cooling Device (DCD)

  • This patented technology is a hallmark of Candela lasers. The DCD delivers a burst of cryogen gas onto the skin milliseconds before the laser pulse, protecting the epidermis and ensuring patient comfort. It’s integrated into models like the GentleLase, GentleMax, and GentleYAG.

4. User Interface

  • Touchscreen Display: Most Candela lasers feature an intuitive touchscreen interface that allows the practitioner to adjust settings like energy level, pulse duration, and spot size.
  • Software Controls: Advanced software in Candela lasers ensures precise control over laser parameters and stores treatment protocols for different procedures.

5. Cooling System

  • Internal Cooling: All Candela laser systems include an internal cooling mechanism to maintain optimal operating temperatures, ensuring consistent performance and longevity of the laser.
  • External Cooling Options: Besides the DCD, some models are compatible with external cooling devices, such as Zimmer coolers, which can further enhance patient comfort.

6. Power Supply

  • High-Voltage Power Supply: This component is crucial for generating the necessary energy to power the laser. Candela lasers have robust power supplies designed for sustained operation during long procedures.
  • Footswitch: Many models include a footswitch that allows the operator to control laser activation easily.

7. Calibration and Safety Mechanisms

  • Calibration Tools: Candela lasers often come with built-in calibration features or external calibration tools to ensure the laser is delivering the correct energy output.
  • Safety Interlocks: Multiple safety interlocks prevent accidental firing of the laser and ensure that the device operates only when all safety conditions are met.

8. Laser Cavity and Optics

  • Mirrors and Lenses: The laser cavity includes high-precision mirrors and lenses that focus and direct the laser beam. These components are made from materials that can withstand the high energy levels produced by the laser.
  • Resonator: The resonator amplifies the light within the laser cavity, a critical part of producing the coherent laser beam.

9. Filters and Beam Modifiers

  • Optical Filters: Specific models may include filters to adjust the wavelength of the emitted light or to block unwanted wavelengths.
  • Beam Shapers/Expanders: These accessories modify the shape and size of the laser beam to optimize it for different procedures.

10. Replacement Parts and Consumables

  • Lamp/Bulb Replacement: The flashlamps used in some Candela lasers need periodic replacement as they degrade over time with usage.
  • Cryogen Canisters: For the DCD system, replaceable cryogen canisters are needed. These are specifically designed for the cooling system and must be replenished regularly.
  • Handpiece Windows: The protective windows on handpieces may require replacement due to wear and tear or contamination over time.

11. Accessories

  • Distance Gauges: These help in maintaining the correct distance between the handpiece and the patient’s skin for consistent results.
  • Spot Size Adapters: Different spot sizes can be used for different treatments, and these adapters attach to the handpiece to modify the treatment area.

 


Conclusion

Each Candela laser model is built with precision and attention to detail, ensuring that every component works together seamlessly for effective and safe treatments. While the core components like the laser head, delivery system, and cooling device are common across most models, the specifics can vary depending on the model and its intended applications. Proper maintenance and timely replacement of parts are essential for the long-term performance of Candela lasers.

Candela lasers are renowned for their precision and reliability across various dermatological and aesthetic applications.
