WebOften, fiber cleavers are pre-adjusted for silica fibers with the standard diameter of 125 μm. For fluoride fibers or other mid-infrared fibers, for example, one may have difficulties finding suitable parameters for repeatable cleaving results. Fibers with particularly large diameters, e.g. beyond 200 μm, can also be difficult to cleave. WebThe emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient ε = 1. The emissivity coefficient - ε - for some common materials can be found in the table below. Note that the emissivity coefficients for some products …
