Ultraviolet Galvanometer Scanner

Base on phase-shifting technique, the laser interferometer, widely used in the high-precision measurement of planar and spherical optical components, characterizes the three-dimensional topography of the measured surface with a precision of 0.06 μm (Peak-to-valley) or higher.

The Computer Control Optic Surfacing Polisher Basing on industrial robot, The surface error is figured by the polishing spindle tool, using for optical plane, spherical and aspheric surface. The fitting polishing tool technology basing on the polishing force controller was developed to get the controllable Influence Function and finish the precision optical surface. And High Mark will provide full process solutions from micron to nanometre with the innovative process technology and software.

The machine is used for the processing of high-precision thin sheet optical elements.

Faraday rotator is based on the nonreciprocity of magneto-optical materials, that is, it can rotate the polarization planes of the normal incident light and the reverse incident light of the same wavelength to the same direction and the same angle, independent of the beam propagation direction. If a Faraday rotator with 45 degree rotation of the polarization plane of the incident beam is placed between a pair of polarizers orthogonal to each other to form an optical isolator, it only allows the forward propagating beam to pass through the system and blocks the backward propagating beam. Faraday rotator is an important component of optical isolator, which is widely used in various laser systems, such as multi-stage laser amplifier, optical parametric oscillator, ring laser, erbium-doped fiber amplifier, seed injection laser, optical switch, optical modulator and so on.

Crystro supplies TSAG-grade TGG. TGG is an excellent magneto-optical crystal material, which is used in all kinds of Faraday isolators and rotators. The applicable wavelength is 400nm-1100nm (except 475-500nm). Products certified by international customers (https://www.en.crystro.cn/the-role-of-luagce-scintillator-crystals-in-radiation-detection-2/).

YIG has superior optical and microwave properties. In the field of optics, the Faraday effect of yttrium iron garnet can be used to manufacture mid-infrared isolators, laser modulators, fiber optic current sensors and other products; In the field of microwaves, YIG has high Q resonance characteristics, which can be used to manufacture magnetic resonance filters, tuned oscillators, bandpass filters and other products. Currently, YIG single crystals are mostly used among the wavelength of 2000-4000nm.

Fiber galvanometer scanner is mainly applied to the laser marking and laser welding devices.

It provide different polishing and grinding plats with different specs, which could be used in the polishing and grinding of different kinds of optical glasses, quartz, crystals and other fragile flat and sphere surface.
