Mini Free-Space Optical Isolators for Laser Systems Deliver High Isolation in Compact Design

April 23, 2025
Edmund Optics' Mini Free-Space Optical Isolators offer high forward transmission in a ~Ø10 x 10.5 mm package.

Mini Free-Space Optical Isolators are compact components that protect ultrafast and continuous-wave lasers by blocking back-reflected light. With dimensions of ~ Ø 10 x 10.5 mm (0.4 x 0.4 in), these isolators support high isolation performance while maintaining forward transmission. Their small footprint supports integration in space, weight, and power-constrained environments (SWaP), such as aerospace, quantum, and research systems.

Designed for embedded systems and production modules, these isolators help ensure clean mode-locking, reduced jitter, and stable power output.

Features:

  • ~Ø 10 x 10.5 mm (0.4 x 0.4 in) footprint
  • Small, <1 cm³ form factor
  • Greater than 70% minimum transmission and >30 dB minimum isolation
  • Input apertures as low as 1.6 mm (0.06 in)
  • High optical isolation
  • Maintains forward transmission
  • Supports ultrafast and continuous-wave lasers
  • Suitable for embedded and production systems
  • Enables laser stability in compact environments
  • Designed for aerospace, quantum, and research use
