Changchun Yutai Optics Co., Ltd.
CaF2 / Fused Silica / CaF2 Triplet Lenses The choice needs to be weighed against the specific needs of the application. Triplet achromatic lenses made of fused silica(SiO2) and calcium fluoride(CaF2) materials are used to correct chromatic aberration mainly through the different dispersion characteristics of these two materials. Fused Silica (SiO2): Abbe number: High (about 67.8), a low dispersion material. Refractive index: moderate (about 1.46 in the visible range). Transparent range: good from ultraviolet to near infrared. Calcium... (read more)Browse Optical Lenses Datasheets for Changchun Yutai Optics Co., Ltd. -

Cylindrical Lenses Types of Cylindrical Lenses. A cylindrical lens is characterized by both its focal length and its geometry. They can be square, circular, or rectangular. A plano concave cylindrical lens will expand light on a single axis. It is also known as a negative cylindrical lens, and is used for one-dimensional image compression, anamorphic beam shaping, and laser line generation. A plano convex cylindrical lens focuses light on one axis, and can also be used to magnify an image in one direction... (read more)Browse Optical Lenses Datasheets for Avantier Inc. -
