103 series laser drivers come with ultra low noise, and the current value can be 100mA, 200mA, 250mA, 500mA or 1A. This laser driver, ATLS200MA103, is one of 103 series laser drivers. It is used for driving diode lasers with up to 200mA low noise current. As shown in the photo below, this laser driver has a very small size so that it can save a lot of space for most of applications. The input voltage is 5V and the output voltage is 1.5V to 4V. The noise is as low as 2.5AP-P @ 0.1Hz to 10Hz. Ther...(more)
ATI designs and manufactures multi-types of laser drivers, and this laser driver, ATLS100MA103, comes with ultra low noise. This laser driver is used for driving diode lasers with low noise and maximum output current of 100mA. Besides low noise, this laser driver features a compact size, which saves a lot of spaces in most applications. It is enclosed in a six sided metal enclosure for zero EMIs. This laser driver is powered by a 5V power supply and outputs a voltage from 1.5V to 4V. Since this...(more)
TEC controllers are designed for driving TEC modules in a temperature control system. In order for easy evaluation on TEC controllers, evaluation board TECEV104 is developed. This evaluation board can be used with all the TECA1 series TEC controllers in ATI, such as TECA1-5V-2.5V-D, TECA1-3V-3V-D, TECA1-3V-2.5V-D, etc. This evaluation board TECEV104 is purposed for tuning the external compensation network of TEC controller in order to match the characteristics of users thermal load. This will mi...(more)
Thermo-electric cooler is also called TEC module, which is short for it. Our TEC controller is designed for driving such TEC modules with high efficiency and stability. TECA1-xV-xV-D is one of our TEC controllers. It is designed to regulate the object temperature with several interface ports, such as set-point temperature, the maximum output voltage across TEC, and the compensation network. This TEC controller comes with high efficiency, up to 90% and more. The maximum output current is 2.5A. It...(more)
ATI manufactures various types of TEC modules, including standard TEC modules and long life thermal cycling TEC modules. The former features good performance and low cost, and the latter has a longer life time when being used in thermal cycling applications. ATE1-TC-127 series TEC modules are among the thermal cycling long life TEC modules. This series TEC modules include two types, one is sealed TEC module, and the other is non-sealed one. The sealed TEC module can be applied in moisture enviro...(more)
Thermal cycling TEC modules can also be called long life TEC modules, which are often used in thermal cycling applications. ATE1-TC-71 series TEC modules belong to this kind of long life thermoelectric coolers. As the part number shows, this series TEC module comes with 71 pairs of Peltier elements, with the maximum currents of 5.5A and 7.8A, thus the power ratings being different. There are two flat ceramic plates on both side of TEC modules, and they can be mounted to other metal surfaces with...(more)
By Gang Liu, Nan Shi, and Hongtao Zhou, Analog Technologies, Inc. Chopping a laser beam is often a necessary practice. For a diode laser, it is much simpler and less costly to chop the beam electrically, rather than mechanically. The output laser beam power, PO, versus the laser diode input current, ILD, characteristics are shown in Fig. 1. Fig. 1 Output Laser Beam Power vs. Laser Input Current In this figure, PO is the optical output power of the laser diode; ILD is the laser diode input curren...(more)
TEC modules have two types, one is standard TEC module, and the other is long life TEC module. The former is used for normal applications of heating and cooling objects, and the latter can be used in thermal cycling applications. Thermal cycling applications refer to those with frequent changes between heating and cooling. In these applications, TEC modules are exposed to demanding physical stresses when they shift from heating to cooling. This will significantly reduce the operational life of a...(more)
