Correlator.com aims to supply advanced correlator technologies for light scattering instruments makers. We are not in the light scattering instruments business which means we don't compete with our OEM customers. Our goal is to offer easy to use, low cost correlators so our customers can use them in place of their own correlators or in new instruments.
Flex-OEM correlators have a number of advantages compare to the conventional correlators.
 | High efficiency : real-time correlators. |
| Highly stable: hundreds of correlators based on Flex architecture have been used by customers world wide. |
| Easy to use : no sample time to set, no prescale to worry about. |
| Easy to program: 32 bits Windows library is very easy to use. |
| Low cost. |
| Reliable supply. Historically, we have always met our delivery schedule. |
We offer two types of multiple tau correlators, USB based (external) and ISA based (internal).
USB based correlators:
A. Supports Windows 98/Windows 2000.
B. There are three physical form factors for USB correlators as pictured below.
| Picture A. PCB size 2.2"x2.6". 3 Mounting holes. Hole diameter 0.125". No external power supply required. |
Picture B. PCB size 2.2"x2.6". 3 Mounting holes. Hole diameter 0.125". No external power supply required. |
Picture C. PCB size 4.4"x3". 4 Mounting holes on each corner. Hole diameter 0.125". No external power supply required. |
