Plano-Concave Rectangular Cylindrical Lenses

A cylindrical lens is a lens that focuses light on a line instead of a point, like a spherical lens. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line and leaves it unaltered in the direction parallel to it (in the tangent plane). In a light sheet microscope, a cylindrical lens is placed in front of the illumination objective to create the light sheet used for imaging. Cylindrical lenses focus or expand light in one axis only. They can be used to focus light into a thin line in optical metrology, laser scanning, spectroscopic, laser diode, acousto-optic, and optical processor applications. They can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical lenses are widely used in telecom applications like WSS, 40G/100G modules and laser applications like pump laser modules

Plano-convex circular cylindrical lenses are useful for line imaging or uni-axial magnification in a wide range of applications. These lenses may be combined with other lenses to form complex imaging systems.

Cr4+:YAG (Y3Al5O12) crystal is ideal for passive Q-switch operation of Nd:YAG and other Nd3+ or Yb3+ doped laser crystals in the wavelength range of 900 nm to 1200 nm. Passive Q-switches or saturable absorbers provide high power laser pulses without electro-optic Q-switches, thereby reducing the package size and eliminating a high voltage power supply. A remarkable feature of Cr4+:YAG is the high damage threshold of >10 J/cm2@1064 nm, 10 ns. Its absorption band extends from 900 nm to 1200 nm and peaks around 1060 nm with a very large absorption cross-section.

Plano Concave Lenses are ideal for beam expansion, light projection, or for expanding an optical system's focal length. Plano Concave Lenses, which have one concave surface, are Optical Lenses with negative focal lengths. Plano-Concave Lenses should be shaped with the plano, or flat, surface towards the desired focal plane.Plano-Concave Lenses are ideal for use in a range of applications or industries. HG OPTRONICS offers Plano-Concave lenses with a variety of coating options.

Holmium-doped Yttrium Aluminum Garnet (Ho:YAG) is an important solid-state laser crystal. Due to the excellent physicochemical properties of theYAG matrix, it can withstand high thermal loads and is an important pumpsource laser crystal for mid-wave infrared lasers. At the same time, it is alsoan ideal light source for coherent Doppler wind radar, differentialabsorption radar, and laser rangefinders.
