The ASB-W-020 is a complete light source assembly with a tungsten-halogen lamp that emits in the 300 to 2500 nanometer (nm) wavelength region. It has been designed to transfer the maximum possible illumination to a variety of fibers. The tungsten-halogen lamp of the ASB-W-020 is a near blackbody source of light with a built-in fused silica lens that focuses the light to the fiber. Figure 1 shows blackbody spectral distributions at various color temperatures in Kelvin (K). The ASB-W-020 spectral distributions resemble those of Figure 1 out to about 2500nm, beyond which the transmission of the fused silica lens limits the output. In addition to the 20 Watt tungsten-halogen lamp (SP # ASB-W-020B), the ASB-W-020 features a lamp housing and a current regulator to assure a stable output. The housing contains an adjustable lamp mount. A variety of flanges allow the mounting of different fiber terminations, from a single fiber to bundles. The 20 Watt tungsten-halogen lamp used in the ASB-W-020 has a nominal color temperature of 3100 K and the regulated power input assures an average life of 2000 hours. The power supply provided with the ASB-W-020 is a wall plug-in type. The power supply provided with the ASB-W-020 is a wall plug-in type. Feature Value Lamp: Tungsten-halogen Power: Wall transformer, 120 VAC, 50/60 Hz to 24 VDC at 2.0 amps. 220 VAC version available Current Regulation: Built-in, ± 0.4% Color Temperature: 3100°K Bulb Life: 2,000 hrs. average (nominal) Spectral Distribution: Near blackbody (see Figure 1) Housing: Aluminum, forced air cooled, Limited focus adjustment Connector: SMA Fiber connector Options: Spare lamp ASB-W-020B Mounting flange for 10mm fiber bundle Optical bench mounts Specify FC, ST or CS for specific fiber couplers. Warranty: One year
