Higher Cost: Solid-state lasers tend to have higher initial costs compared to some other laser types, making them less accessible for certain applications.

Lasers have transformed numerous industries with their unique capabilities and precise control of light. However, different types of lasers offer distinct advantages and disadvantages, making them suitable for specific applications. In this article, we will explore the advantages, disadvantages, and applications of various laser types, enabling a better understanding of their strengths and limitations.

Convex lens imaging

Each type of laser offers its own set of advantages, disadvantages, and applications, making it important to carefully consider the requirements of a specific application. Solid-state lasers provide high power and precise beam quality, gas lasers offer versatility in wavelength and high power, semiconductor lasers are compact and efficient, and fiber lasers combine high power scalability with excellent beam quality. Understanding the strengths and limitations of different laser types is key to selecting the most appropriate laser for a given application, ensuring optimal performance and successful outcomes.

Telecentric lenses are used in innumerable vision applications, and in particular they form the critical component of the optical system when precise measurement is required. Non-contact measurement applications demand the use of such lenses which, thanks to their low distortion, can eliminate perspective errors (parallax effect) due to imprecise positioning or objects with strongly 3D geometries.

Opto Engineering offers a vast range of precision telecentric and bi-telecentric lenses for the most diverse requirements of the market: models for high and low resolution area and line scan sensors in a variety of magnifications and working distances; classic, compact and flat lenses, along with standard and custom solutions. The range also includes special telecentric lenses: lenses with integrated liquid lenses, zoom lenses, optical benches and other special products. Opto Engineering 360° view lenses are unique designs that make it possible to inspect an entire product while reducing the number of components in the vision system. Thanks to their special optical design, just one camera is needed to simultaneously inspect multiple surfaces of an object: the bottom and internal surfaces, or the top and external surfaces. The family includes multi-view lenses which give a single image of the object containing a variety of points of view. Many of these 360° view lenses represent an innovative way of resolving vision applications, previously considered impossible, in a simple and effective way: they are used in numerous industries, from food & beverage to pharmaceutics and automotive. Some of these extraordinary optical innovations are the fruit of Opto Engineering’s R&D, have been patented internationally, received numerous awards, and constitute an extremely valuable resource for our clients.
