WTC32ND TEC Temperature Controllers

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  

The WTW002 thermal washer can be used to go between the WHS302 heatsink and following laser diode drivers and temperature controllers from Wavelength Electronics: WTCP5V5A, WTC3243, WTC3243HB, WHY5640, WLD3343, WLD3343-2L, WLD3343-3A, WLD33ND-3L or WLD3343HB.The WTW002 thermal washer is made of a non-silicone, flexible graphite material, and does not break down or out-gas under high heat conditions. One side has adhesive. We recommend that you install the adhesive side to the heatsink. The controllers operate to 500 mA without any additional heatsinking (assuming 5 V operation). To operate up to 1 A, add the WTW002 thermal washer and the 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 Flexible graphite Adhesive backing Thermal conductivity up to 5 W / mK Extends the Safe Operating Area of the WLD, WTC, and WHY

Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless SteelFiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11.Additionally, the fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
