Laser speckle reducers & beam homogenizers

Laser speckle reducers (LSR) & beam homogenizers

Optotune's laser speckle reducers are nothing other than moving diffusers. But the way they are actuated is absolutely unique.

Applications:

• Laser speckle reduction
• Beam homogenization

Reluctance force LSR

Launched in 2016, the reluctance force LSR is particularly suitable for applications that require large format glass diffusers. The basis of this approach is a single thin steel structure that is brought into resonance by pulsing an actuating coil with current, which generates a strong reluctance force. Thanks to a high q-factor large amplitudes in the range of 800um are achieved at low power consumption even for heavy glass diffusers.

Advantages:

• Compact design with integrated actuator
• Works with different diffusor materials
• Driving electronics integrated on flex-cable
• Robust design for harsh environments
• Long operational lifetime
