λ/10 Spherical Lenses Datasheets

Spherical Lense -- Bi-Concave Lense
from Intrinsic Crystal Technology Co., Ltd. (ICC)

These lenses have negative focal lengths. These lenses diverge collimated incident light and form virtual images, which are seen through the lens. They are often used to expand light or increase focal lengths in existing systems. [See More]
