BK Right Angle Prisms with AR Coating
BBAR Coated Hypotenuse Right Angle Prisms
Right Angle Prisms are typically used to bend image paths or for redirecting light at 90°. Right Angle Prisms are Prisms designed with a 90° angle. Right Angle Prisms produce inverted or reverted left handed images, depending on the orientation of the prism. Using two Right Angle Prisms together is ideal for image or beam displacement applications. These prisms are also known as image reflection or reflecting prisms.
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.
High Precision Penta Prisms
N-BK7 Penta Prisms
Penta Prisms are used to define right angles in optical systems. Penta Prisms, which provide right handed images,feature a ray deviation of 90°. Penta Prisms are five-sided prisms are unaffected by slight movements. Uni Optics offers a variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums.
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.
Dove Prisms and Roof Prism
BK7 And Fused Silica Glass Dove Prisms
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.
Dispersion Prisms
30° - 60° - 90° Littrow Dispersion Prisms
Dispersion Prisms are used in applications that require separating the incident light into its component wavelengths. For example, when white light enters a Dispersion Prism, it is separated into its three components: red, green, and blue. Dispersion Prisms are ideal for spectroscopy or laser tuning.
BK7 Anamorphic Prisms
High performance anamorphic prism
The Anamorphic prisms are used in pairs to magnify input beam size along one axis while leaving the other axis unchanged. The elliptical laser diode beams can be transferred into nearly circular.
Rhomboid Prisms
High Precision Rhomboid Prism
The Rhomboid prism application for rhomboid-prism is controlling and redirecting the optical path without affecting the image direction. They can be used to displace an optical center line for light beam folding and stereoscopic systems of different sizes.

· Developed for 1" image format
· Wavelength: 900-1700nm
· Large Aperture, upto F1.4

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.

Metallic Coated Mirrors
N-BK7 metallic coated mirror

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.
