UV Grade Fused Silica Plano-Convex Lenses


◢Plano-Convex Lens

Plano-Convex Lenses is a spherical lenses with one flat surface and one convex surface with a positive focal length. The PCX lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optic lenses are ideal for all-purpose focusing elements.

CLZ Optical Co., Ltd. manufacturing UV Grade Fused Silica plano-convex lenses with high performance. Our plano-convex lenses are assure the surface accuracy with ZYGO Verifire Interferometer - 4". The lenses are precision manufactured using UV grade synthetic fused silica. We can provide coatings with antireflective coated on both faces with multilayer AR for 248-400nm use. However UV grade fused silica can be used efficiently at 185nm transmitting over 85%.

A plano-convex lens is an optical element that focuses light at a distance and refracts it. It has a concave section and a convex spherical surface. It is one of the most commonly used optical elements today and is ideal for many general imaging applications.

N-BK7 plano-convex lenses are made of high-grade glass and offer excellent optical clarity and high durability. These lenses are designed for applications that require precision and high performance with minimal aberrations. They provide excellent transmission and outstanding power for visible and near-infrared applications.

The plano-convex lenses made from N-BK7 have high uniformity and low impurity content. This eliminates light scattering, shadows and distortions associated with other lenses. These lenses provide superb performance for imaging applications with very low blur. It provides clear images with minimal aberrations and meets most imaging needs.

Fused silica plano-convex lenses are designed for extended wavelength applications and are made of advanced optical glass materials that provide excellent optical uniformity and low dispersion. These lenses have excellent transmission of light in the infrared spectrum, which is ideal for applications requiring good detail and clarity. Because of their excellent transmission, they are often used in infrared imaging applications.

Plano-convex lenses also have a high transmittance of no less than 500 nm. This is a very important factor, as transmittance is an important factor in optical performance. High transmittance provides excellent brightness and resolution, as well as minimal noise when viewing images. The uniformity and low aberrations associated with these lenses make them perfect for a wide range of imaging projects.
