These GRIN lenses are designed for use at 630, 830, 1060, 1300, or 1560 nm. The 1300 nm and 1560 nm lenses are particularly suited for telecom applications due to their ease of use with small beams and negligible chromatic aberration over telecom wavelengths. Additionally, the 1300 nm and 1560 nm lenses have a broadband AR coating that reduces reflectivity of the interfaces to ≤0.2% over 1250 - 1650 nm. The GRIN2306A also has a V coating for 630 nm.
