Lenses

The world of technology is constantly evolving, pushing the boundaries of what is possible. In this ever-advancing landscape, one crucial component stands out - the silicon dome. CLZ Silicon domes are a critical part of semiconductor technology, as they provide a protective and efficient means of encapsulating electronic components. These domes are made from high-quality silicon, a material renowned for its exceptional electrical properties, as well as its ability to withstand extreme temperatures and harsh environmental conditions. Let's delve deeper into the incredible features and functionalities of silicon domes. At the heart of the silicon dome is the semiconductor material. Silicon is a widely-used semiconductor due to its unique ability to regulate the flow of electricity. This property, combined with its abundance and cost-effectiveness, makes silicon the ideal choice for various industries, from consumer electronics to aerospace. Silicon domes offer a robust and reliable environment for sensitive semiconductor components, ensuring their longevity and optimal performance.

Our MgF2 coating can be less than 1.75% reflectance @ 400-700nm, AOI=0°. And we can produce high-precision optical components that make up achromatic lenses according to customer requirements before cemented. Achromatic lenses are designed to minimize chromatic aberration, a common optical issue where different wavelengths of light focus at different distances. This leads to color fringing around images. By combining two or more lens elements made from different types of glass, achromatic lenses bring multiple wavelengths of light into focus at the same point, resulting in a clearer and sharper image.Magnesium fluoride (MgF2) coating is applied to lenses to reduce surface reflection and enhance the transmission of light through the lens. This coating improves the performance of optical systems by reducing glare and increasing contrast.

A biconvex lens is a positive lens characterized by a longer focal length in the middle and shorter focal lengths at both ends. These lenses are used in a wide variety of applications such as camera lenses, projectors, telescopes and microscopes. Bi-convex lenses are often used to expand light beams. In this article, we discuss the properties, functions, and applications of biconvex lenses for beam expansion. Bi-convex lenses are made of optical glass and are convex on both sides. The center of the lens is thicker than the edges, which provides a focal point for the light rays entering the lens. Light rays entering the lens are refracted and converged to the focal point. The distance between the focal point and the center of the lens is the focal length. The focal length of a biconvex lens depends on the curvature of the lens and the refractive index of the glass.

The Triplet Lenses are made of a low index crown element cemented in between two identical meniscus flint elements. Specially designed for 1:1 conjugate ratios. But sometimes customers' Triplet Lenses have different designs. CLZ optics supply custom triplet lenses made from your custom design and specification. We control the strict centering before cemented to ensure good performance after cemented, the lenses centration is tested on our Centration Measurement and irrgularity is tested on our ZYGO to ensure the lenses meet your designs. Optical triplet lenses are a type of compound lens system composed of three individual lens elements. Each lens element has a specific optical power and curvature designed to work together to correct various optical aberrations, such as spherical aberration, chromatic aberration, and coma.
