Optical Prisms

Fused silica is a high performance optical material with ultra-broad spectral transmission, low thermal expansion, and high laser damage threshold for ultraviolet (UV), visible (VIS), and infrared (IR) spectroscopy systems. Read more...

Precision right angle prisms for beam steering, optical path folding, and beam control in laser systems and optical platforms. Read more...

BK7 wedge prism is an optical component made of BK7 optical glass, featuring a wedge-shaped structure (two flat surfaces tilted at a slight angle). It is primarily used for beam deflection, collimation, or optical system alignment in the visible to near-infrared (NIR) wavelength. Read more...

BK7 dove prism is a classic dove prism made of BK7 optical glass, widely used in optical imaging, laser systems, and instrumentation, primarily for image rotation or adjusting the direction of the light path. Read more...

The BK7 penta prism is a cost-effective optical path deflection component for the visible light spectrum, suitable for imaging, measurement, and low-power laser systems. For UV or high-power laser applications, a fused silica penta prism is recommended. Read more...

Avantier manufactures precision infrared optics — lenses, prisms, windows, mirrors, and laser/imaging assemblies — for aerospace, thermal imaging, spectroscopy, night vision, defense, and medical diagnostics. Diamond-turning technology delivers sub-nanometer surface finishes and sub-micrometer form accuracy, with every component tested to ISO and MIL standards for reliable pe... Read more...

What are the core features of roof prisms? Image orthogonality: maintains the left-right and up-down orientation of the image in line with the original. Compactness: shorten the physical length of the optical system by folding the optical path. High precision requirement: the 90° angle of the roof surface needs to be extremely precise (error ≤ a few seconds), otherwise it will l... Read more...

A right angle prism is a common optical prism with two right angled edges forming a 90° angle and a beveled (slanted) surface that serves as the reflecting or transmitting surface. It is widely used in optical systems for beam steering, imaging, beam combining/splitting, and other applications. Read more...

The light pipe prism is an optical component used for guiding and distributing light, typically made of transparent materials such as glass, acrylic, or polycarbonate. Read more...

Fused silica right angle prisms are made of high purity fused silica with excellent optical performance and environmental stability for UV, VIS and NIR wavelengths, especially suitable for laser systems, high precision optics and harsh environments. Read more...
