GCL-0107 Air-Spaced Achromatic-Doublets
Exceptional optical quality
The achromatic lenses with large aperture are air-spaced. All the air-spaced achromatic doublets show exceptional performance and provided with mounts.
When used for focusing or collimating, the convex lens or the smaller radius surface always faces the collimated light, while used to image, the convex lens must be adjacent to the object or image with longer distance.
Please note that air spaced achromats are shipped in two pieces and need a special mount.
