Non-Magnetic Fiber Collimators
Features
• Titanium housing
• Adjustable focus
• Diffraction limited
• Low wavefront error
• Wavelengths from 350nm to 2100nm
• Designed for singlemode fibers
Designed to be used in very high magnetic fields, these fiber collimators are made entirely of non-magnetic materials and offer diffraction limited performance.
Our multi-element, air spaced design has low wavefront error and comes in various beam sizes. Focus is adjustable so you can tune to your wavelength and lock it down. Output is highly collimated and minimizes any diffraction effects. Optical design minimizes or eliminates any fluorescence typically found in other collimators.
All collimators have a broadband AR coating with very high transmission and cover four different regions from 350nm to 2100nm
Housing and it’s receptacle are made of titanium. All other materials are ceramic or glass. The collimators have an FC or FC/APC receptacle.
