Fused Silica is formed by chemical combination of silicon and oxygen. Fused Silica is perfect optical material due to its good UV and IR transmission, low coefficient of thermal expansion. It has high stability and resistance to thermal shock over large temperature excursions, wide temperature operating range and high laser damage threshold.
Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. UNI Optics can provide the size from Φ1~Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to OEM customers upon request.
Concave-convex aspherical lenses are commonly used to correct spherical aberration and improve imaging quality in optical systems, especially where high resolution and compact design are required. Their aspherical surface design enables better light focusing and reduced distortion compared to traditional spherical lenses.
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.
