Most importantly, it adopts the RAMMER brand under the Sandvik brand, with internationally advanced technology and processes, and is a well- known guarantee. Hydraulic hammers are also made of imported high-quality materials and controlled by hydraulic and pneumatic systems. Large crushing capacity, smooth operation, low noise, reliable performance, convenient operation, energy-saving and environmental protection, capable of continuous construction operations in any complex working condition on-site. The small static Rockbreaker boom system is a lightweight multi-purpose crushing equipment commonly used in quarries, next to the primary crusher, to remove all blockages in the stationary crusher and mobile crusher. The medium static Rockbreaker boom system is similar to the small series, but the medium Static type boom system is mainly designed for open pit and underground mine applications.

Optical mirror is an optical element which has reflective function. Accordingly shape, it can divide into three parts, that is flat mirror, spherical mirror, aspheric mirror. Accordingly, degree of reflection, it can divide into two parts, that is total reflection mirror and half reflecting mirror. On the back of the optical glass make a metallic silver or aluminum or gold film by vacuum coating to reflect the incident light. First surface mirror the reflected image has no distortion, no glint, and it’s also called front surface mirror, it’s widely used for optical high-fidelity scanning reflection imaging, beam bending, interferometry, imaging and illumination. Commonly use polishing glasses or metal as substrate made a reflected coating on it, including metal film and dielectric coating, metal coating material including gold, silver, aluminum, aluminum mirror has very high reflection rate from UV to IR, film fastness and stable, silver mirror have high reflectance ratio from VIS and IR, AOI changed slightly and low polarization effect, gold mirror has very high reflectance rate, strength and stability in IR area, better than silver coating. Metal film is soft and easily to scratch and damage, so it’s often plated with a protective film outside the metal film, if need high reflection ratio choose dielectric coating film, it can improve the reflectivity and reduce the absorption loss. AOI and wavelength will affect the reflectance ratio, commonly AOI is 0° or 45° CCRQ supply flat surface mirror, spherical concave mirror, cylindrical mirror, elliptical mirror, right angle prism mirror, Hot mirror, cold mirror, Flat mirror etc, many of stock size for choosing, select a coating appropriate to your application or contact us with your need wavelength and wavelength range, more choosing as following, more details please contact us directly.

Optical prism is an optical element which accordingly incident light and outgoing light to make turning ray of light. In the optical path, the prism can making the light offset and changing the direction of the image and also has the function of changing the angle of outgoing and incident light, such as deflection 90° or 180°.Prim widely used on laser research, laser optical systems, optical image, machine vision and other fields and products. Right Angle prism also called Right Angle Bending Prism, because it can turn light 90° by internal reflection of hypotenuse, or turn light 180° through two right angle prism surfaces, accordinlgy customers demand. Many different coatings applied to these prisms, some common types are Anti- reflection coating on two legs, Aluminum protected coated on hypotenuse by black sealing paint to ensure grazing incidence reflection and two angle surface make VIS AR or NIR AR, accordingly customers demand. These prims are suitable for optical delay lines and for high power use.

An Aspheric Cylindrical Lens is a specialized optical component designed to focus or shape light along a single axis, typically used in applications requiring precise beam shaping or correction of optical aberrations.
