Visible And NIR Plate Beamsplitters

Polarization Beamsplitter Cubes are constructed by cemented two right angle prisms, the hypotenuse of one prism is coated with polarization dielectric coating. When used with normal incident, un-polarized light, the incident beam is separated into two polarized beams, p-polarized component is passed straight through, s-polarized component is reflected out at 90deg.

Non-Polarizing Cube Beamsplitters also called NPBS Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces.The cemented face of one prism is coated. Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection could be designed to 10%, 20%, 30%, 40%, 50%, etc.

Beamsplitter Cubes are constructed by cemented two right angle prisms.  The hypotenuse of one prism is coated with polarization dielectric coating.

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. This difference in velocities gives rise to a phase difference when the two beams recombine.

Invented by H.W. Dove, Dove Prisms are also known Reversion prisms.  When the prism is rotated about its length axis, the image viewed through the prism rotates at twice the prism rotation rate.  This is an unusual and sometimes useful property for special applications. Entry and exit faces are anti-reflection coated.

Nd:GdVO4, is a promising material for diode pumped lasers. Similar to the more well-known Nd:YVO4 crystal, Nd:GdVO4 crystal also exhibits high gain, low threshold, and high absorption coefficients at pumping wavelengths. Nd:GdVO4 has the additional advantage over Nd:YVO4 of a much higher thermal conductivity. For CW lasing at 1.06 um and 1.34 um and intracavity doubling with KTP and LBO, the gadolinium vanadate have produced a higher slope efficiency or optical conversion than Nd:YVO4.

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.
