These probes are primarily used to collimate the diverging output from an Oriel Fiber Bundle. To collimate the output from our liquid light guides, use one of the probes described on page 262. Move the fiber bundle away from the lens to produce a focused image, far from the probe. To image at short distances use a focusing probe. The 77644 Probe has a fused silica, 19 mm effective focal length lens. It captures and collimates the output cone from fused silica bundles. The 77645 has a low F/# compound glass lens with an 11 mm effective focal length. It collimates the highly divergent output from glass bundles, and transmits over their useful spectral range. We also offer models with a shutter between the bundle and collimating lens, to cut off the beam and check the "radiometric zero." Tech Note You cannot produce a well collimated beam from a large aperture fiber bundle. The smallest divergence angle, for a perfect optical system is given by: = Tan-1 d f Where: è = Full angle divergence d = Fiber bundle diameter f = Lens effective focal length • Collimate output from fiber bundle • Models with and without integral shutter Ordering Information Model Optic Material Shutter 77645 Glass No 77644 Fused Silica No 77653 Glass Yes 77652 Fused Silica Yes See our website WEBfor more info
