About Royan

CLZ Optical Co., Ltd. is one of China leading optical manufacturing companies. We manufacture a wide range of optical components for many different fields like Industrial Laser, Consumer products, Environmental Monitoring, Photography and Aerospace and R&D. We were established in early 2012 in China�s Optical Manufacturing hub of Changchun.

Concave (Focusing ) Mirrors are often used in applications

Royan14 May, 2025Business

Concave (Focusing ) Mirrors are often used in applications that require light collection. The reflective surface bend inwards to focus light toward the inner focal point. When the parallel light shines on concave mirrors. It reflects on the focal point in front of the mirror through its reflection. The reflective surface is the concave surface.

Dense Flint Glass is referred to as ZF glass

Royan14 May, 2025Games

Dense Flint Glass is referred to as ZF glass. It has the characteristics of high refraction and high dispersion. The density is great. It is the glass with the highest lead content in the Na2O-K2O-PbO-SiO2 system, and the mass fraction of PbO is greater than 55%. Because of its high lead content, this type of glass can be used as a radiation protection glass in addition to being used as a material for optical parts

Plano (Flat) mirrors are Optical Mirrors

Royan14 May, 2025Entertainment

Plano (Flat) mirrors are Optical Mirrors designed for a variety of applications, with a flat reflection surface. If an optical system can form a perfect image with random wide beam in any large space, namely, any concentric beam can still be kept as a concentric beam after passing through the system, then this system is an ideal optical system.

Flinting Glass is referred to as F glass

Royan14 May, 2025Business

The narrowly defined flint glass belongs to the Na2O-K2O-PbO-SiO2 system, and the mass fraction of PbO is between 40% and 55%. The refractive index and density increase with the increase of PbO content. Mainly used as a material for optical parts in optical instruments, such as Spherical Lenses and Cylindrical lenses.

Coating Witness Samples

Lanthanum Crown Glass is referred to as LaK glass or lanthanum glass. Located in the upper left corner of the nd-v diagram. Lanthanum glass from CLZ Precision Optics has the optical characteristics of high refraction and low dispersion, so it is often called high refractive index and low dispersion optical glass together with lanthanum flint and heavy lanthanum flint glass.

Barium Crown Glass

Barium Crown Glass is referred to as BaK glass or crown glass. The refractive index and density are between K and ZK glass. Crown glass is basically a borosilicate glass containing barium, zinc, potassium, and sodium. It contains a lot of barium, and the mass fraction of the sum of BaO and ZnO is about 20%-40%. Mainly used as a material for optical parts in optical instruments, such as optical lenses, prism and Cylindrical lenses.
