Alrad Instruments Ltd

Through our six technology divisions, ALRAD Imaging, ALRAD Electronics, ALRAD Photonics, ALRAD Medical, ALRAD Thermal and ALRAD Vacuum, we offer thousands of product items from the world's leading manufacturers. We also provide installation, demonstration, and product support services. 

We represent many of our principals as their sole distributor in the UK. Some of these exclusive companies have been with us since the 1970s, many of our distribution agreements have been in place for a very long time and that must say something about the service we offer. The products and service we provide open up new opportunities for our customers to improve quality,automation and productivity which is why many of our existing customers have been experiencing ALRAD high quality service for decades.

Alrad employ experienced staff to help our customers generate a competitive edge for their companies backed by world class products.

Alrad are members of the UKIVA (United Kingdom Industrial Vision Association) group of organizations and companies within the PPMA ( Processing and Packaging Machinery Association).

  1. Frame Grabbers NEON-DIF

    Frame Grabbers NEON-DIF

    The Neon-DIF

    The machine vision industry is constantly advancing with new buses, new interconnect standards and new software standards. However, many applications do not require cutting edge technology or require "tried and true" standards. Some applications are simply recycling older technology, following the "why throw it out if it still works?" motto. With this in mind, BitFlow has introduced the Neon-DIF. We have taken our robust Neon platform and replaced the camera link front end with a 32-bit differential interface. In some ways, this board is the best of both worlds - it melds the latest PCIe speed and features with older, but very robust, differential data devices.

    Simplify your industrial, medical, or semiconductor imaging application with BitFlow's Neon-DIF, the easiest to use and most reliable differential frame grabber available anywhere. The Neon-DIF captures images at speeds up to the camera's highest frame/data rate, with precision image acquisition suitable for the most demanding applications.

    The Neon-DIF is designed for the OEM customer looking for the performance of the PCI Express bus, a differential interface, and one of the lowest price points in the industry. The target markets are applications where the current frame grabber is no longer available but the camera and application are still important. Another niche that this product fills is differential applications where the PC needs upgrading, but the frame grabber has a PCI interface. Motherboards with PCI slots are getting harder and harder to find. Finally, customers who want to port their application to 64-bit Windows are finding that their differential frame grabbers are not supported on newer operating systems. The Neon-DIF can handle all of these situations.

    The Neon-DIF is not just for legacy situations, however. There are still a tremendous number of devices that output differential data that may not even be cameras. The Neon-DIF can acquire from just about anything and efficiently DMA the data into host memory.

    Adding the Neon-DIF to your application is simple with our SDK, which supports both 32-bit and 64-bit operating systems. The SDK provides high level APIs for sophisticated buffer management and low-level direct access to the board for speedy custom control.
