Buying Gradient-index Lenses
Gradient-index lenses (GRIN lenses) provide focusing without any curved surfaces. They are widely used for fiber beam collimation, fiber-to-fiber coupling, endoscope objectives, and as mode field adapters and contact lenses, offering precise control over light propagation in compact optical systems.

Lenses with a zero working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. Each lens is available uncoated (approximately 12% reflection loss), or with a BBAR coating option for R < 0.5%. Product-specific web page |
