RFH 355nm UV laser has good performance and stable quality

Last week, a customer from an optical glass laser cutting and drilling plant just placed an order to purchase a batch of RFHExcellent Ⅱ 355 series water-cooled ultraviolet lasers.

Today, let's talk about a special kind of glass-optical glass. Optical glass is a glass material used to manufacture lenses, prisms, mirrors, windows and other components of optical instruments or mechanical systems, and is a key element. The manufacturing standards of optical glass are very strict. Some of its parameters, such as the value of refractive index, must be strictly guaranteed within the design tolerance range, otherwise it is a waste product. So, how is such a high standard special glass made? Next, listen to RFH to tell you carefully.

First of all, the raw materials for mass-produced optical glass in general industry are monolithic. It is necessary to perform preliminary cutting and perforation according to the designed shape requirements, and then perform finishing and coating. So how are these thin and brittle glass cut? At first, the cutting was performed with a precision CNC spindle cutter, but the quality was difficult to control, and the yield rate was far from the expected value. Later, more sophisticated lasers were introduced to solve the problem and realize batch processing.

 

At present, there are two main types of lasers used in optical glass cutting and perforation, ultraviolet lasers and green lasers. Below, take a laser cutting machine using our RFH Excellent Ⅱ 355 series water-cooled UV laser as an example to explain why the UV laser cutting machine can become the mainstream optical glass cutting and drilling processing equipment.

 

1. This Excellent Ⅱ 355 series water-cooled UV laser has a laser wavelength of 354.7nm, a wide range of repetition frequency (single pulse to 200kHz), superior beam quality (M2<1.2), and strict guarantees in all frequency ranges ; Pulse width <16ns@40k, the heat-affected area is small during processing, this laser beam quality can ensure the processing quality of optical glass: narrow incision, smooth cutting edge, small chipping, and high processing speed, suitable for large enterprises Batch processing and production; 2. Unique Q-switching control technology, suitable for various laser application control needs; Contains online refresh harmonic control technology, power stabilization time is super long, there is no need to worry about performance degradation after a period of time, which is also a lot One reason why manufacturers choose to use our lasers; third, is it difficult to operate such a sophisticated laser? Not so. In fact, its operation is very simple. It supports communication with a computer and can control the laser externally through RS232. At the same time, it adopts all-digital intelligent power control technology and monitoring is also very convenient.

 

How does RFH make this first-class quality laser? This is to talk about our R&D team and production management system. RFH has a top-level laser research and development team composed of professors and doctors from Tsinghua University. It has established an application process research and development department, a laser research and development department, and an electrical research and development department. This is a solid backing for the stable operation of the RFH laser system; at the same time, we also have strict quality For the management system, we invested heavily in the construction of a dust-free production workshop. The quality control department strictly controls the incoming materials, production, machine acceptance, and shipment to ensure product performance and quality. Because of this, RFH has won high recognition and good reputation from users in all walks of life at home and abroad.

 

After 12 years of hard work, RFH Laser has established an excellent brand image in the nanosecond laser industry.
