Indus SL20 - 20mm TIR Optic

Indus SL20 20mm High-Efficiency Mid-Power Single TIR Lenses

The Indus SL20 Series from Fusion Optix is a family of precision-engineered single 20 mm diameter total internal reflection (TIR) lens optics designed for high-efficiency beam control with mid-power LED packages including 2835, 3030, and similar emitters.

Optimized for uniform illumination, high optical efficiency, and compact luminaire integration, the Indus SL20 family enables designers to achieve precise beam shaping across architectural, commercial, industrial, and specialty lighting applications.

The series includes multiple beam distributions and surface textures to support narrow spot, medium, wide, diffuse, and linear illumination requirements.

Designed for Mid-Power LED Platforms

Unlike optics originally developed for high-power single-die emitters, the Indus SL20 Series is engineered specifically for modern mid-power LED architectures.

The optics are optimized to deliver:

• Uniform beam appearance
• Reduced color separation
• High optical transmission
• Controlled glare
• Compact mechanical integration
• Consistent performance across multi-package arrays

Compatible LED footprints include:

• 2835
• 3030
• Similar mid-power LED packages
