New version of the ALV/CRTU Cuvette Rotation Unit now features stepper motor drive
ALV/LSE-5004, the latest model of the ALV-Light Scattering Electronics is now available
From 01.04.2007 on, the ALV-Light Scattering Electronics ships in the latest version, ALV/LSE-5004. Featuring some significant improvements over previous models, it as well shows significantly reduced power consumption and is of course fully RoHS compatible. In detail, the following features have been added compared to the ALV/LSE-5003 version
RoHS conformal products
ALV’s new building
ALV moving to a new building on October 27/28 2005
With moving to the new building, a newly build facility and therefore customized to ALV’s needs, ALV will be able to serve the customers needs even better, because of an significant increase in available space combined with a reorganisation of all the processes involved in manufacture/assembly and test of our products. In addition, a training center for groups of up to 12 people is part of the new building, offering the opportunity to have combined training with direct access to the instruments etc. pp. An update on this with pictures will follow as soon as possible.
All phone/fax numbers and e-mail addresses as published on this homepage will be unchanged, still, from October 31 on, the new address for shipments to ALV should read
Support for ALV-Software running on
WIN-95/98 operating system to be discontinued by 01/01/2005
Important Information for using ALV-Correlator Control Software with INTEL HyperThreading CPUs !
All ALV-Correlator Control Software versions < 220.127.116.11 will not work properly with HyperThreading CPUs. These CPUs, with their ability of simulating two “virtual” CPUs being installed on the system, seem to lack certain synchronization mechanisms which were naturally “given” with just a single CPU installed and are present in an real DUAL-CPU system as well. Effectively these CPUs must be declared “incompatible” in these situations, situations, which do not introduce problems for the overwhelming number of applications, since exact synchronization of software threads is not at all required, but do infact impose significant problems, whenever such synchronisation is mandantory, as is the case in many measurement oriented applications.
Possible Workarounds in case you encounter problems (in particular strange CR-Displays, obviously wrong AutoScaling or hang-up in the AutoScale routine , spurious count-rate alerts ...):
