ModularOne offers our clients laser driver modules and thermoelectric controller, or TEC, modules that provide very accurate temperature control. A module, such as a thermoelectric controller, is comprised of everything that is required to perform a specific function. In very little time, you can be operating with your own application. Our TEC modules and laser driver modules may be customized. We ask all prospective customers to contact us about their applications before placing order; this way, we can provide any necessary assistance, and confirm suitability of a particular module for an application. If you decide to invest in miniature modules, you should also consider purchasing evaluation boards (EVMs). These will allow you to experiment with various features to see if they are appropriate for your application. OEM boards (PCB+Module) allow instant use of a given module in a product.
