Optotune’s laser speckle reducers offer a compact turnkey solution for speckle reductionand beam homogenization using an oscillating AR-coated fused-silica diffuser. The reliableactuation technology delivers stable performance for over 40,000 hours.
From speckle-free laser illumination in fluorescence microscopy to brighter, higher-contrast laser projection with expanded color gamut, these systems enhance signalquality, increase detection accuracy, and effectively eliminate unwanted laser speckle.
- Compact design with large aperture
- Driving electronics integrated on flex-cable
- Robust design with long operational lifetime
- Built-in amplitude stabilization
Static diffusor (LSR OFF): 0.26 speckle contrast
Dynamic diffusor (LSR ON): 0.06 speckle contrast

Compact de-speckling
Optotune’s LSR-4C reduces speckle through dynamic diffusion, rapidly moving a diffuser to average multiple interference patterns and deliver a uniform, speckle-free beam. With its large 18.5 × 18.5 mm aperture, it is built for high-power, large-beam applications such as laser cinema projection. The metallic frame and reluctance-based actuation ensure reliable motion.
Key advantages:
- Large 18.5 × 18.5 mm aperture supports high power and large beam diameters
- Compact electronics with closed-loop resonance stabilization
- Optional dual 90° diffuser configuration for optimized bi-directional de-speckling
- Integrated error signal for system monitoring
