A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam. A simple lens is a lens consisting of a single optical element. A compound lens is an array of simple lenses (elements) with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element. Manufactured lenses are typically made of glass or transparent plastic. Elements which refract electromagnetic[...]

Windows are applied to isolate different physical environments while allowing light to pass. When selecting windows you should consider materials, transmission, scattering, wave front distortion, parallelism and resistance to certain environment. China star optics offers a wide range of different materials and different degree of precision windows. Specification of our optical windows as follow: *Material: Bk7 or other materials *Length tolerance:+/-0.01 *Width tolerance:+/-0.01 *Center thickness[...]

Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.
