Laser Optics

Prisms are transparent optical devices which refract or reflect light. They have manifold applications in laser technology.

Laser Lenses are used to focus collimated light from laser beams in a variety of laser applications. Laser Lenses include a range of lens types including HGQ Lenses, Cylinder Lenses, or Laser Generator Lenses. Laser Lenseare designed to focus light in several different ways depending on the lens type, such as focusing down to a point,a line, or a ring. Many different lens types are available in a range of wavelengths.

Laser Protect Windows(Laser protective glass, protective filters or welding protective windows) are used to save for the high cost of laser optics.

Laser mirrors are fabricated with specialized coatings, which will offer high damage thresholds.

HGO have advanced coating machines which can meet endusers’different application requirement. We can very high laser induced damaged threshold coating with IAD, EB and IBS coating techniques , also Cr-Au, Aluminum and silver mental coating can also be available in HGO. Customers are very welcome to contact with us for further information.

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.

α-BBO (α-BaB2O4) is a negative uniaxial crystal which has large birefringence over a broad transparent range of 190nm to 3500nm. α-BBO is an excellent crystal especially in UV and high power applications. The physical, chemical, thermal, and optical properties of alpha-BBO crystal are similar to those of Beta-BBO. However, there is no second order nonlinear effect in alpha-BBO crystal due to the centrosymmetry in its crystal structure and thus it has no use for second order nonlinear optical processes. Instead, alpha-BBO is widely used for fabrication of polarizers, polarizing beam displacers, phase retarders, birefringent plates, and time delay compensators especially those for UV and high power lasers.

Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. HG OPTRONICS  can provide the size from Φ1～Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to customers upon request.
