Custom Optical Wedge Fabrication
Sydor Optics manufactures custom optical wedges used in a variety of applications. Flat optics with a wedge angle are typically used in laser applications for beam steering and beam displacement or for preventing stray-back reflections, and can also be used in virtually any type of optical component to change the direction of light.
With decades of experience Sydor Optics is the preferred choice for exceptional cosmetics, wedge angle tolerance and surface roughness. Optical wedges are manufactured to meet your exacting specifications in a wide variety of custom shapes, sizes, materials with optional coatings for ultraviolet (UV), visible (VIS) and infrared (IR) applications.

Popular MaterialsCrystal
Optical crystals are glass-like materials grown from high-purity raw materials. The most common crystals include calcium fluoride—effective for UV-spectrum applications—and magnesium fluoride, which is useful for mid-wave IR applications.
- Magnesium Fluoride (MgF2)
Popular MaterialsDisplay Glass
Borosilicate glass, also called display glass, offers a combination of excellent light transmission and impressive technical properties. Made of silicon oxide and boron oxide, display glass is easily laser- or CNC-machined. In addition to having excellent chemical resistance, the material possesses a low coefficient of thermal expansion, meaning that it can resist high temperatures without cracking.Popular MaterialsFused Quartz
Fused Quartz is made using high quality, natural quartz powders with several fusion methods. Quartz material is stronger than glass, can be used at high temperatures (<1050°C) and has a high average transmission of over 80% from 260nm to 2500nm. The various qualities of fused quartz allow for use in a wide range of applications from semiconductor applications to lower precision window applications in hostile environments.- Heraeus HOQ 310

Popular MaterialsFused Silica
Fused silica is a transparent glass formed by melting and cooling pure silica sand. Unlike most other glasses, fused silica does not contain any additives. It is an amorphous solid with a purity that gives it excellent optical transmission.- Corning HPFS 7979 (UV & IR Grades)

Popular MaterialsIR Materials
Infrared materials produce good transmission in the infrared (IR) spectrum, which spans 0.75 μm to 15µm. Infrared materials are commonly selected for their transmission properties in the NIR (0.75µm – 1µm), SWIR (1µm – 2.7µm), MWIR (3µm – 5µm) or LWIR (8µm – 12µm) spectral sub-regions. The most common IR materials are silicon, germanium, sapphire, zinc sulfide, and zinc selenide.
- Germanium
- Sapphire
- Zinc Sulfide
- Zinc Selenide
Popular MaterialsLow Expansion
Low expansion glass-ceramics are characterized by a near-zero coefficient of thermal expansion and excellent resistance to thermal shock. These materials have high purity and chemical stability, with minimal internal stress.Popular MaterialsOptical Glass
Optical glass is known for its high transmission, low dispersion, and homogenous refraction indices. These properties result from the continuous melting process and subsequent finishing methods used to create optical glass. This material is categorized into either flint glass or crown glass. Flint glass has an Abbe number < 55 and generally < 50. Flint glass is denser due to the inclusion of various metal oxides and exhibits strong chromatic dispersion. Crown glass has an Abbe number> 50 and generally > 55. Crown glass is typically less dense resulting from higher usage of alkali metals and exhibits low chromatic dispersion.- Hoya BSC7
