Product Description
Double Ball Glass Objective Cemented Telescope Lens
Product Overview
Optical telescope doublet achromatic lens double ball glass objective lens double sapphire welding cemented lens
A cylindrical lens with convex surfaces and square volume can turn a transmitted plane wave into a cylindrical wave, or turn an original cylindrical wave into a plane wave or spherical wave. Such a kind of lens can correct ocular astigmatism.
Cemented Lens Technology
The cemented lens, also called an achromatic lens, is formed by cementing two single lens elements. The performance of multi-color (white light) imaging is much higher than that of a single lens. The achromatic lens consists of two lenses of different materials glued together to correct the dispersion of the glass. Eliminating the problem of chromatic aberration, achromatic lenses have been widely used in multi-color lighting and imaging, improving cost-effectiveness.
