Our fully-automated crystal growth control system offers complete control over every phase of the process of crystal growth, from seeding, necking, shouldering, and equal diameter growth all the way to finishing. This can provide a strong guarantee on both the consistency of crystal bars and the stability of products.

We use high-precision cutting machines to process external and internal cylinders, which in turn contributes to a high level of production efficiency and ensures our products can be cut to high dimensional accuracy. This accuracy has led to numerous customers coming back to us time and again, knowing they will be getting the best possible products. Red laser light diffraction is carried out for testing a wide range of optical materials. With the use of single-shaft polishing machine and optical rolling machine, we can shape the square materials into round cylinders. This guarantees a small tolerance, high pass rate and superior efficiency.

We can grind our products to the required size, perpendicularity and parallelism according to the customer’s order. The laser crystal bars, which are available in various sizes, are precisely ground in a single run for increased production efficiency.

We have invested in more than 20 sets of 4-shaft polishing machines which can perform laser polishing on the end face of the laser crystal with high levels of accuracy and efficiency.

The industrial grade ultrasonic cleaning system is utilized to ensure the uniform cleanliness of all workpieces. Prior to coating, cleaning and wiping need to be carried out in order to ensure the smoothness of the coated laser crystal meets specification requirements. Our company has introduced high-performance coating machines from different countries. These facilities, combined with IAD and EB coating techniques, can adapt to a variety of application requirements.

In this workshop, we own a host of cutting-edge optical test facilities. One example of our test facilities is the spectrophotometer that comes from Japanese Shimadzu. We take strict measures to ensure the quality of our products.

Crystal growth workshop

Single-crystal growth Furnaces
The crystal growth control system is fully automatic, which means that from the initial seeding stages, through necking, shouldering and equal diameter growth, all the way to finishing, are automatically controlled. This ensures the consistency of the crystal bar, and guarantees the stability of all products.

Real-time microcomputer single crystal pulling growth control system
The swing phenomenon that occurs in the operation of a single crystal furnace rotary and pulling system is both modeled and numerically simulated. This ensures the primary growth process of the YAG crystal become automatic, which increases both the growth quality and yield of the products.

Cutting and coarse grinding workshop

Round cutting machine
We use diamond saw blades to achieve high speed cutting. In addition to straight cutting, simultaneous long and square stocks cutting, it can also cut prism blanks at specialized angles. The high production efficiency is favorable for massive production.

Material selection by testing the diffraction spot of the red light laser
This method allows the parallel laser to penetrate into the interior of the crystal. Different materials are chosen by observing the ovality of the diffraction spot by placing a round circle at the light outlet.

We use the laser to guarantee that all the crystals chosen from the blank material are free of cores or side cores.

Inner circle cutting machines workshop
We use the rolling bearing of vertical spindle structure, which has a rigid, precise and unshakable axis and feeding system with a stepper motor and motivation to drive the module in order to guarantee the stability and precision of the system.

Single axis grinding and polishing work area

Single axis grinding and polishing machines grind square stock into prismatic shapes

Measure the circular degree of the laser crystal
First grind the products from a square shape to a polygon shape, and then barrel them from prismatic to a cylinder in a single run. The key factors are precision and yield. A small tolerance guarantees high yield and high efficiency.
