Compared with beamsplitter plate, beamsplitter cube has the following advantages:


* Identical path length for both the reflected and the transmitted beams
* The transmitted beam is neither displaced nor deflected
* Stable and compact
* Easy operation
* Easy for mounting/aligning

Beamsplitters Plates
Visible and NIR Plate Beamsplitters
Our beamsplitter plates can be used in high power laser system. When using beamsplitter plates, it is important to make it in mind that the two partial beams travel in different optical paths. The optical paths depend on the incident angle and the thickness of plates.
Non-Polarizing Cube Beamsplitters
Non-Polarizing Cube Beamsplitters (NPBS)
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.
Polarizing Beamsplitter Cubes(PBS cubes)
Polarizing Beamsplitter Cubes
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.

1、What Metallic Coated types can Uni-Optics supply?


Uni-Optics mainly offers four coating types, including:

1) UV Enhanced Aluminum : Ravg > 85% from 250nm to 400nm

2) Protected Aluminum: Ravg > 87% from 400nm to 800nm

3) Protected Silver: Ravg > 95% from 400nm to 20um

4) Protected Gold: Ravg > 98% from 650nm to 16um



2、What are the features of Metallic coated mirror?


Metallic coated mirror have many key features below:

Wide spectral range

Not sensitive to the incidence angle and polarization state

Low cost

Non-durable

Relatively low reflectance

Low laser damage threshold


3、What UNI Optics can do for you?


Common Specifications:

Substrate Materials: N-BK7, Fused silica, Pyrex;Float glass

Dimensional tolerance: +/-0.1mm

Surface quality:  60-40

Parallelism:  3’

Flatness: λ/4 per 25mm@633nm

Bevel: Protective

One surface: Polished and Metallic coating

The other surface: Fine ground


Note: Aluminum is the most widely used metal reflection film, from near UV to near IR, have high reflectivity, and with low cost. Silver has higher reflectivity in the visible and near infrared wavelength than the aluminum film, but the silver in the air will be rapid oxidation, color darkening, makes the film performance and firmness declined rapidly. Gold film has a good consistency with high reflectivity in the near, middle and far infrared range, can control the thermal radiation effectively, but it is relatively soft, easy bruising, and should be paid very close attention to clean, and the cost is very high.




Beamsplitter Penta Prisms
MgF2 Coated, Penta Prism Beamsplitter
Beamsplitter Penta Prism by adding a wedge and with partial reflective coating on one of its leaning surfaces, Penta Prism can be used as Beamsplitter. Transmission/reflection (T/R) ratio of 50/50, or others for Beamsplitter Penta Prism is available upon request.
Crown Glass Double-Convex Lenses
MgF2 Coated Double-Convex (DCX) Lenses
Double Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCV Lenses are used in a range of industries or applications. Uni-Optics offers Double Convex lenses with a variety of coating options.

Corner Cube Prisms with blacking painting
N-BK7 Corner Cube Retroreflectors Prisms
Corner Cube Prism also called  Retroreflector. It has three mutually perpendicular surfaces and a hypotenuse face. Light entering through the hypotenuse is reflected by each of the three surfaces in turn and will emerge through the hypotenuse face parallel to the entering beam regardless of the orientation of the incident beam. For its special performance, it is often used to the distance measurement, optical signal process and laser.
Colour glass window
AR coated Colour glass window
Color glass changed the spectral properties of optical radiation. They therefore allow scientific experiments and industrial applications where that change is necessary. You can combine color glass filters together to change the bandpass or to increase the attenuation.
Fused Silica Wedges Prisms
N-BK7 and Fused Silica Wedge Prisms
Wedge prism is an optical element with plane-inclined surfaces, usually the faces are inclined toward one another at a very small angles.  It diverts light toward its thicker portion.  Wedge prisms can be used as isolating components. Wedges may also be used to produce a small deviation which doesnt allow return to source.
