Dove Prisms
Dove Prism has two applications. The main application is used as a rotator. It can rotate an image but without deviating the beam. And when the prism is rotated about the input parallel ray through some angle, the image rotates through twice that angle. It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean. Another application is used as a retroreflector. For this application it perform as a right-angle prism.

[Sell] Achromatic Lenses(Doublets) |
|
|
Lenses have many applications in range from the simple collection of the scanning of laser beams to precise imaging and image transferring.
Achromatic (Doublets)Lenses Achromat consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. The elements are chosen so as to cancel chromatic aberration at two well-separated wavelengths, usually in the blue and red region of the spectrum. Focal length is constant at those two wavelengths and focal length shifts are virtually eliminated across the visible wavelengths. One frequent use is to achieve diffraction limited focusing of a laser beam. Negative Achromat is typically used when there is a need to eliminate chromatic aberration. In addition to reducing chromatic aberration at the design wavelengths, spherical aberration and coma are greatly reduced.

Laser Line Polarization Beam Splitting Coating
This coating can generate special high reflectance to S-polarization and high anti-reflection to P-polarization for laser application.It can achieve nearly 100% reflectance to S-polarization and 100% transmission for P-polarization on a narrow wavelength range.Therefore,its main application is to be used as polarizing beam splitter for single wavelength laser system when it is deposited on glass substrate, but its extinction ratio is so high.
Broadband Polarization Beam Splitting Coating
This coting has similar application with laser line polarization beam splitting coating ,but it can be used for a wide wavelength rang.

[Sell] Polarization 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.

[Sell] Beamsplitter Plates |
|
|
Beamsplitter Plates : can be used with high power laser. When using beamsplitter plates, it is important to bear in mind that the two partial beams travel different optical paths. And the optical paths depend on the incident angle and the thickness of plates.

[Sell] Beamsplitter Cubes |
|
|
Beamsplitter Cube is a more sophisticated type consisting of two right- angle prismscemented 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 approach 50%.
