SF8XXX Laser Diode Drivers and TEC Temperature Controllers

330 W @ 20°C; >2 lpm @ 14 psig; 1/4 Valved CPC Fittings; Centrifugal Pump; Aluminum This thermoelectric recirculating chiller is a low-cost, high-performance device optimized for lasers, optics and life sciences. It features precise temperature control (±0.05°C repeatability), long-life reliability, quiet operation and environmental friendliness in a compact size. Using universal power, the TEC chiller is very energy efficient only drawing power when required.

The PLDEVALPCB evaluation board is used with following laser diode drivers from Wavelength Electronics: PLD6500, PLD5000, PLD1250, PLD500 or PLD200. It simplifies benchtop operation of the PCB mount drivers and reduces prototyping time. This evaluation board does not include the laser diode driver itself. It includes a terminal strip for easy wiring to the power supply and laser diode. DVM cable ready test points monitor the setpoint, current limit, and photodiode signal voltages. These voltages are also on the terminal strip along with the LD Enable and Modulation inputs. Onboard switches select main power on, enable / disable, and whether the DVM point monitors laser or photodiode current. An LED indicates when main power is on. A shorting bar ties the high compliance input to +5 V. It can be removed for high compliance voltage operation. Remote computer control is available using the separate available USBKIT, which also allows graphing and datalogging.

Polarization Maintaining; 480 to 1625 nm; Fiber Type PANDA, others; Insertion Loss ≤0.4 to ≤1.5 dB; Operating Temperature Range -20 to +70 °C OZ Optics’ PMJ series of polarization maintaining (PM) patchcords are based on a high precision butt-style connection technique. The PM axis orientation is maintained by using male connectors with a positioning key and a bulkhead female receptacle with a tightly toleranced keyway, ensuring good repeatability in extinction ratios and insertion losses.The polarization axis of a fiber is aligned with the connector key by rotating either the connector frame or the fiber itself until the polarization axis is in line with keyway of the connector. Once the fiber is correctly aligned, the alignment can be fixed with a drop of glue or epoxy. OZ Optics minimizes backlash and rotational errors in the PM axis alignment by using specially designed PM ferrules and connector housings.Patchcords are normally offered pre-aligned and referenced with the slow axis aligned to the connector key for optimum coupling efficiency and extinction ratios. Non-angled FC PM connectors are also available unaligned and unlocked (rotatable) for lab use. Unless otherwise specified, pre-aligned patchcords are oriented such that the slow axis of the fiber is aligned with the key of the connector and locked. These patchcords maintain polarization to better than 20 dB. Higher extinction ratios are available upon request. In general, OZ Optics uses polarization maintaining fibers based on the PANDAfiber structure when building polarization maintaining components and patchcords. However OZ Optics can construct devices using other PM fiber structures, including 80 µm cladding sizes. If necessary, OZ Optics is willing to use customer supplied fibers to build devices. OZ Optics uses a 2.00 mm housing key for its standard FC/PC PM connector design. This is known also as a type “R” keywidth. Also available are FC/PC connectors with a 2.14 mm housing key (Type “N”). Sleeve through adaptors are available to connect same size keys or to convert from a 2.00 mm to a 2.14 mm key connector. In addition to patchcords and sleeve through adaptors, OZ Optics provides male PM connectors and ferrules for fiber termination, bulkhead receptacles to attach fibers to devices as well as ferrules for different fiber sizes.
