Off Axis Collimators
Bertin Winlight’s off-axis collimators are designed to meet the instrumentation and characterization needs of military, space, and industrial environments.
Thanks to an optical architecture using off-axis aspheric mirrors, Bertin Winlight’s off-axis collimators offer full spectral coverage from the visible to the far infrared (LWIR), exceptional accuracy, high thermal stability, and no chromatic aberration.
We offer standard configurations suitable for a wide variety of use cases, while also offering the possibility of developing customized solutions according to your specific needs.
• Optimized for long focal lengths, without compromising image quality
• Spectrally versatile, from visible to LWIR
• Proven mechanical and optical stability
• For laboratory or field use
