Fused silica window, with low thermal expansion, providing stability and resistance to thermal shock over large temperature excursions, wide thermal operating range and high laser damage threshold, is a better choice for transmission from UV to IR.
BK7 window is the most common type of window. It has good performance over visible and near infrared wavelength regions. At the same time, BK7 window is ideal for applications require minimal transmitted beam deviation. It is suitable for AR coating.
Sapphire window retains its high strength at high temperatures, has good thermal properties and excellent transparency. It is chemically resistant to common acids and alkali at temperatures up to 1000 °C as well as to HF below 300 °C. These properties encourage its wide use in hostile environments where optical transmission in the range from the vacuum ultraviolet to the near infrared is required.
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.
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.
Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber. Uni Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR.
