RFH 355nm Solid State UV  laser solves the problem of laser cutting and drilling of optical glass

Last week, a customer from an optical glass laser cutting and drilling factory placed an order for a batch of RFH 355 series water-cooled Solid State UV  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 it is a key component. The manufacturing standards of optical glass are very strict. Some of its parameters, such as the refractive index value, must be strictly guaranteed to be within the design tolerance range, otherwise it will be a waste product. So, how is such a high-standard special glass made? Next, listen to RFH tell you carefully.

Solid-state 355 nm ultraviolet laser drilling glass

First of all, the raw materials of optical glass mass-produced in the general industry are all in one piece. It needs to be cut, punched, etc. according to the shape requirements of the design first, and then finished and coated. So how are these thin and brittle glasses cut? At first, the precision CNC spindle cutter was used for cutting, but the quality was difficult to control, and the yield rate was far below the expected value. Later, more sophisticated lasers came out, which solved the problem and realized batch processing.

At present, there are two main types of lasers used in optical glass cutting and drilling, ultraviolet lasers and green lasers. Next, take a laser cutting machine that uses our RFH 355 series water-cooled Solid State UV  laser as an example to explain why Solid State UV  laser cutting machines can become mainstream optical glass cutting and drilling processing equipment.

1. This 355 series water-cooled ultraviolet laser has a laser wavelength of 354.7nm, a wide repetition rate coverage (single pulse to 200kHz), excellent beam quality (M2<1.2), and is strictly guaranteed in all frequency ranges; pulse The width is <16ns@40k, and the heat-affected zone is very small during processing. Such laser beam quality can ensure the processing quality of optical glass: narrow incision, smooth cutting edge, small edge chipping, and fast processing speed, which is suitable for enterprises to carry out mass production. Processing and production; 2. It has a unique Q-switching control technology, which is suitable for various laser application control requirements; it contains online refresh harmonic control technology, and the power stability time is super long, so you don’t have to worry about performance degradation after a period of time. This is also the choice of many manufacturers. One reason to use our laser; 3. Will it be difficult to operate such a precise laser? Not so, in fact its operation is very simple, it supports communication with the computer, and the laser can be controlled externally through RS232; at the same time, it adopts all-digital intelligent power control technology, and the monitoring is also very convenient.

Wie hat RFH einen so erstklassigen Qualitätslaser hergestellt? Hier geht es um unser F&E-Team und unser Produktionsmanagementsystem. RFH verfügt über ein erstklassiges Laserforschungs- und -entwicklungsteam, das sich aus Professoren und Ärzten der Tsinghua-Universität zusammensetzt, und hat Abteilungen für die Forschung und Entwicklung von Anwendungsprozessen, Abteilungen für Laserforschung und -entwicklung sowie Abteilungen für elektrische Forschung und Entwicklung eingerichtet, die die solide Grundlage dafür bilden der stabile Betrieb des gesamten Lasersystems von RFH; Managementsystems haben wir viel Geld investiert, um eine staubfreie Produktionswerkstatt für den gesamten Prozess zu bauen, und die Qualitätskontrollabteilung kontrolliert streng die eingehenden Materialien, die Produktion, die Maschinenabnahme und den Versand, um die Produktleistung und -qualität sicherzustellen. Aus diesem Grund,

Nach 16 Jahren harter Arbeit hat RFH Laser ein hervorragendes Markenimage in der Nanosekundenlaserbranche aufgebaut.
