Optical optimization for osteoarthritis

Treatment of hand osteoarthritis** The combination of 660 nm (red light) and 850 nm (near‑infrared light) is scientifically grounded for this type of application. While 660 nm is absorbed in the upper layers of the skin and supports surface‑level circulation, 850 nm has the ability to penetrate deeply into joint capsules, tendons, and bone tissue. For osteoarthritis, this deeper penetration is considered important for addressing inflammation and discomfort in the small finger joints.Since the goal is a therapeutic tool for your wife, I have optimized the design and printing process to ensure she gets the maximum benefit from the bulb:---## **Optical optimization for osteoarthritis applications**When using white PETG, the shade acts as a diffuser. For hand osteoarthritis, this is actually an advantage:- **Even irradiation:** Instead of the light hitting only from the front (which can create hotspots), the parabolic shade reflects the light so it reaches the joints from multiple angles.
