Pulsar R25-4 - 25mm 4Up TIR Optic

Compact 25mm Total Internal Reflection Multi-Package Optics for Uniform Distribution

The Pulsar R25-4 from Fusion Optix is a series of precision-engineered 25mm diameter total internal reflection (TIR) 4Up 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 MT20 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 Pulsar R25-4 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
