WLD33ND 2.2A Laser Diode Driver

The WHS302 heatsink can be used to support following laser diode drivers and temperature controllers from Wavelength Electronics: WTCP5V5A, WTC3243, WTC3243HB, WHY5640, LDTC 2/2 O, LDTC 2/2 E, WLD3343, WLD3343-2L, WLD3343-3A, WLD33ND-3L or WLD3343HB. The controllers operate to 500 mA without any additional heatsinking (assuming 5 V operation). To operate up to 1 A, add the thermal washer WTW002, and WHS302 heatsink. To operate to the full 2.2 A, add a fan WXC303 (5 V) or WXC304 (12 V). For convenience, a kit with two 0.75" and two 1" screws is available: WXC305. Kits combine these elements: WEV300 (includes thermal washer, heatsink and screw kit), WEV301 (includes thermal washer, heatsink, screw kit, and a +5 V fan) or WEV302 (includes thermal washer, heatsink, screw kit, and a +12 V fan).Key Features Convenient and simple design  

Output Current TEC ±2.2 A; PCB Mount; Supply Voltage 5-30 VDC; Temperature Stability 0.0009°C With its compact design, Wavelength Electronics’ WTC32ND series of component type TEC temperature controllers achieves 0.0009 °C temperature stability. Its award winning package can be integrated with a heatsink, thermal washer and fan for easy prototyping. The linear, PI control loop offers maximum stability, while the bipolar current source has been designed for higher efficiency. The WTC32ND series is the new version of the discontinued WTC3243 series of TEC temperature controllers. The WTC32ND series drives up to 2.2 A for either thermoelectrics (bipolar) or resistive heaters (unipolar). With the WTC32ND-HB, a model compatible with Li-ion batteries is available. The WTC32ND-EV evaluation board is available to quickly integrate the WTC32ND series into your system and can be optimized for sensor type. Use the adjustable trimpots to configure heat and cool current limits, proportional gain, and integrator time constant. Wavelength provides the free LabVIEW Virtual Instrument executable file for use with the WTC32ND-EV evaluation board. The source code for the LabVIEW Virtual Instrument module is available for free in case you wish to modify the program yourself. Alternately, Wavelength can customize the Virtual Instrument to suit your application – [InternalLink type="site" label="contact an AMS Technologies sales engineer" target="_blank" id="50" ] for assistance. The WTC32ND series of TEC temperature controllers is easily configured for any design. A circuit calculator tool speeds selection of external component values. Virtually any type of temperature sensor can be used with it and a built-in sensor bias current source simplifies use with resistive temperature sensors. The proportional gain (P) and (I) integrator time constants are set by external resistors and can be modified to optimize temperature overshoot and stability. Other features offer added flexibility. Independent heat and cool current limits are set by single resistors. An onboard reference voltage simplifies potentiometer control of the temperature setpoint. You can also choose to operate remotely with an external setpoint voltage. Monitor actual sensor voltage at pin 9. If you do not need all the features of the WTC32ND, the WHY56ND series of TEC drivers is a lower cost solution that does not incorporate remote voltage control and temperature monitor and requires external circuits to operate anything other than resistive sensors. Two or more WHY56NDs can be used together for more output current. NOTE: The WHY56ND and WTC32ND do NOT have the same pin configuration. Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard products can be easily modified to meet your application requirements. [InternalLink type="site" label="Get in touch with the AMS Technologies temperature controller experts" target="_blank" id="50" ] to discuss your customized solution!

PM or SM Splitters/Combiners; 1550 nm, Other; Splitting Ratio 50/50-90/10; PDL ±0.25 dB; Directivity >50 dB OZ Optics’ fiber optic beamsplitters are used to divide light from one fiber into two or more fibers. Light from an input fiber is first collimated, then sent through a beam-splitting optic to divide it into two. The resultant output beams are then focused back into the output fibers. Both 1xN and 2xN splitters can be constructed in this fashion with as many as eight or more outputs, with both low return losses and low insertion losses. Standard parts available in this series are FOBS-12P (1x2) and FOBS-22P (2x2) pigtail-style splitters, FOBS-12 (1x2) and FOBS-22 (2x2) receptacle-style splitters, as well as LDBS-12P (pigtail-style) and LDBS-1 (receptacle-style) laser diode to fiber splitters, and finally ULBS-12P (pigtail-style) and ULBS-1 (receptacle-style) laser to fiber splitters This design is extremely flexible, allowing to use different fiber types on different ports, and different beamsplitter optics inside. Custom designs combining circulators, polarizing splitters and non-polarizing splitters in the same package are routinely manufactured. Splitters can be made with either fibers permanently attached to each port (pigtail style) or with receptacles on each port that one can plug your fiber into (receptacle style). OZ Optics can also build source to fiber couplers with built-in beamsplitters for either laser or laser diode sources. Contact AMS Technologies for details. If size is a concern, we recommend that you consider OZ Optics’ miniature line of splitters. Within OZ Optics’ series of beamsplitters and combiners, the two most common types of splitters offered are polarizing beamsplitters and polarization maintaining (PM) beamsplitters. Polarizing beamsplitters split incoming light into two orthogonal states. They can also be used to combine the light from two fibers into a single output fiber. When used as a beam combiner, each input signal will transmit along a different output polarization axis. PM splitters use a partially reflecting mirror to transmit a portion of the light from the input fiber to the main output fiber and reflect the remainder of the light to the second output fiber. All ports made using polarization maintaining fiber are aligned so that polarized light aligned parallel to the stress rods on the input fiber emerges from the output fibers in the same manner, maintaining the polarization state to a high degree. Splitters that only split off a small portion of the input light are commonly known as taps and often used for power monitoring applications. For a very cost-effective alternative configuration, combining the functions of a tap and monitor photodiode in a single unit, we invite you to review OZ Optics’ OPM series of inline optical taps and monitors.
