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.
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.
A Plano-Convex (PCX) lens causes light to focus to a point,it has a positive focal length,which is ideal for light collimation or for focusing applications utilizing monochromatic illumination, in a range of industries. Uni-Optics offers PCX lenses with a variety of coating options.
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.
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 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.
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.
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.
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.
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.
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.
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.
