A biconvex lens is a positive lens characterized by a longer focal length in the middle and shorter focal lengths at both ends. These lenses are used in a wide variety of applications such as camera lenses, projectors, telescopes and microscopes. Bi-convex lenses are often used to expand light beams. In this article, we discuss the properties, functions, and applications of biconvex lenses for beam expansion.

Optical Domes as high pressure viewports using in submersibles (Underwater optical dome). Optical glass domes are essential components that are widely used in underwater detection equipment. They are made of optical glass substrate, which is known for its superior optical properties, such as high transparency, refractive index, and low dispersion. These properties make the glass substrates ideal for designing lenses and other optical elements used in underwater detection equipment.The optical dome is an important component in submersibles, it has a wide angle and can be protective of the deep-sea camera.

Optical dome are lenses with two concentric spherical surfaces. Sometimes they are being referred to as bent plan parallel plates. Consequently it is customary to define parallelism between two surfaces as the maximum thickness variation between the two surfaces.

A pyrgeometer is a device for measuring the effective radiation of the Earth`s surface in the wavelength spectrum approximately from 4.5 μm to 100 μm.

Plano-Convex cylindrical lenses are made by UV fused silica, it has excellent UV transmission and low coefficient of thermal expansion.

CLZ precision optics provide custom optical component for laser systems and imaging systems. Such as cylindrical lenses. Plano-Convex Cylindrical Lenses is a common cylindrical lenses,  it available with positive focal lengths, ideal for laser line, uni-axial magnification,  Circularizing the Beam from a Laser Diode and combined with other lenses to form complex imaging systems.

CLZ precision optics provide custom optical component for laser systems and imaging systems. Such as cylindrical lenses. Plano-Concave Cylindrical Lenses is a common cylindrical lenses,  it available with negative focal lengths, ideal for laser line, anamorphic beam expansion. When used in combination with a plano-convex cylindrical lens an elliptical-shaped beam can be shaped into a circular beam.

Borosilicate windows are optically polished to provide outstanding visual quality and optical clarity. Compared with fused silica, they have a lower (although still relatively high) melting temperature, which makes them simpler and therefore cheaper to process. Their thermal expansion coefficient is higher than for fused silica, but still relatively low, resulting in good thermal shock resistance. Compared with N-BK7 windows, they have a higher melting temperature, and good thermal shock resistance.

Optical Windows are flat, plane-parallel plates with ground and polished faces that often used as isolate two physical environments while allowing light to pass. Optical Windows should be selected based on the material transmission or mechanical properties of the substrate and Windows do not cause change in the magnification of a system.
