In contrast, the USB 3.1 internal connectors build upon the USB 3.0 design by offering a more compact form factor and a stronger mechanical latch. While retaining the 20-pin header for single Type-C or dual Type-A connections, it introduces a 40-pin version to support two full-feature Type-C ports. These connectors ensure that the latest USB standards are accessible from the front of PC cases, facilitating easy and efficient connection for a variety of devices.

How to make acollimatedbeam

The laser beam is focused through the focal lens. The focal lens acts like a magnifying glass and sunlight. For a 55mm lens, the laser beam passes through the lens and converges to the smallest point at about 55mm from the edge of the lens. The laser beam is concentrated to the smallest size at this "spot".

There are several types of USB connectors, including USB-A, USB-B, USB-C, Micro-USB, and Mini-USB. Each type has its unique design and use cases, with USB-C being the latest and most versatile.

Collimate telescope

Quite often CW lasers have a short cavity. The resonator of microchip DPSS lasers may vary from less than a millimeter to few millimeters. Cavities of single-mode laser diodes are in the range of hundreds of microns. Generally speaking, such short cavities produce highly divergent beams, which are not very usable in optical systems.

The divergence requirement in microscopy and spectroscopy is often less than 2 mrad (full angle) or even less than 1.5 mrad. In order to meet this requirement of modern analytical instruments, laser beams have to be collimated. This can be understood as putting a lens or a set of lenses in front of the laser cavity – does not matter be it a semiconductor laser cavity or a short DPSS resonator. However, for different types of lasers (diode and DPSS) the beam specifications are completely different.

USB Type B connectors, essential for peripherals like printers and PTZ cameras, are designed with a unique shape to prevent incorrect connections. This design safeguards your devices by making it impossible to connect two host devices together, a scenario that could lead to hardware damage. While the tech world is gradually moving towards newer, smaller connectors, USB Type B's distinct shape and its role in ensuring the right device connections keep it relevant in many setups.

Collimation radiology

If you want a smaller collimating laser beam, you must accept a larger divergence; On the contrary, if we want to keep the collimation of light over a long distance, it must get a larger beam size.

Newnex's Miniature USB cables provide dependable connectivity and swift data transfer speeds, ideal for compact device setups in industrial and consumer applications.

The most simple and popular way is to collimate a laser diode beam by using a single aspheric lens. (see Fig. 1). The larger is the focal length of this lens, the larger will the beam diameter be after collimation. Furthermore, if a certain beam adjustment has to be made, for example in order to expand the beam radius of a collimated beam, two lens system is often used - the so-called telescope. One lens with a negative focal length and the other with a positive one creates a setup to collimate and expand or shrink the beam.

Newnex's USB-A to USB-A cables offer seamless connectivity and high-speed data transfer, meeting USB 3.0 specifications for enhanced performance.

Quite frequently the most popular way to focus a laser diode beam is to use a two lens system where one lens collimates the highly divergent beam and the second lens focusses it. Alternatively, a single aspheric lens can be used to focus the beam for direct focusing, but in most cases, it causes severe aberrations, larger beam and lots of diffractions. By definition, beam quality implies a measure for how well a laser beam can be focused.

USB Type A is the cornerstone of USB connectors, widely recognized for its flat, rectangular shape. This connector is predominantly used on host devices like computers, gaming consoles, and TVs, as well as on USB hubs. It's designed for a unidirectional flow, usually from the host to the peripheral device, which means it provides power along with data transfer. The USB-A connector is versatile, supporting various USB standards, including USB 2.0, USB 3.0, and USB 3.2, with increasing speeds and efficiency.

Mini USB connectors, smaller than the standard USB B, are designed for peripherals needing a compact connection. With 5 pins, including an ID pin, they support USB On-The-Go (OTG), allowing devices like mobile phones to act as USB hosts. Originally popular in early mobilephone, USB Mini B has shifted towards use in digital cameras as devices have trended towards even smaller connectors like micro USB. Today, Mini B serves as a legacy connector, mainly found in specific devices and no longer common for new products.

Newnex's USB-A to USB-B cables deliver reliable connectivity and rapid data transfer speeds, strictly adhering to USB 2.0 standards for industrial and commercial applications.

A diode laser beam features low wavefront quality and high astigmatism - the divergence in the so-called fast axis is much higher than divergence in the slow axis. Various techniques are used for collimating such an astigmatic beam and in this consideration several objectives are important. The primary goal of collimation is to reduce divergence of a beam, the secondary goal is to eliminate astigmatism as much as possible, third – to improve wavefront quality, fourth – to make the beam less elliptical, fifth – to maintain good focusability.

In order to support the higher USB data rate, the USB 3.0 and USB 3.1 internal connectors were developed to serve to connect front panel external USB ports to the motherboard while maintaining signal integrity. The USB 3.0 internal connector features a 20-pin design that supports two USB 3.0 ports, allowing for dual USB-A connectivity at 5Gbps without bandwidth sharing. It's primarily used for linking SuperSpeed (SS) USB ports on the front panel to the motherboard.

USB Mini A connectors, though less common than Mini B, also provided a compact solution for mobile devices and peripherals. Mini A connectors were used in some early mobile devices and portable gadgets. However, like Mini B, the trend towards smaller and more efficient connectors like micro USB and USB-C has made Mini A connectors less prevalent in modern devices.

USB-C, or USB Type-C, is the latest advancement in USB technology, featuring a reversible connector design that works with both host PC and peripherals. It's not just about the convenience of plugging in your cable any way—it's also about universal compatibility and future readiness. USB-C supports a wide range of standards from USB 2.0/1.1 to USB 4.0, with the latter offering impressive data transfer speeds up to 80 Gbps and power delivery up to 240W. This makes it ideal for ultra high-speed data transfer, fast charging (with or without a USB C charger), and connecting display video outputs, including USB C to HDMI.

USB 2.0 cables often use crimp header connectors to connect with motherboard. 5 pin and 10 pin header are the most common seen configurations.

In today's world, USB technology is everywhere, playing a crucial role in connecting the devices we use every day. Yet, choosing the right USB cable can be confusing due to the many different USB types available, often not interchangeable. This can make finding a replacement cable more complicated than it seems, especially if you're not familiar with the subtle differences.
