Model 131 fiber adapter fits to entrance or exit slits of McPherson monochromators. Efficient design proximity couples fiber to slit. Fiber is adjustable to allow alignment to the instrument. Works with ferrule and SMA terminated fibers.

Model 132 fiber adapter fits to entrance or exit slits of McPherson monochromators. This assembly comes with a filter holder (25mm dia x 6mm thick) and two element UV grade fused silica lens system to focus fiber termination to slit. Also matches f/number. Fiber is adjustable to allow alignment to the instrument. Works with ferrule, SMA, FC/PC terminated single and/or fiber bundles.

Model 617A Reflective Focusing accessory is useful for sources and fibers. It uses 2 reflective optics to focus a light source or fiber to the entrance slit. No refocusing and no chromatic aberration provide maximum spectral range. An aperture is provided to match f/nos. McPherson accessory light chopper and filter wheels fit inside this housing next to the slit. Works with ferrule, SMA, FC/PC terminated single and/or fiber bundles.

Multiple fiber mounting and translation assembly fits modified McPherson entrance slit housings. Has micrometer adjustment for translation and vertical positioning of multi-fiber input. Motorized versions optionally available (pictured.) These are useful to remotely select fiber(s) in use or tweak centering / position on detector arrays.

Standard commercial fiber optics and special fiber optics made to your requirements. Single fibers, multiple fiber bundle, random or coherent bundle, liquid light guides, bifurcated bundles, circular to rectangular bundle for efficient energy gathering and transmission through a monochromator slit. Standard fiber optic glass for low cost, fused silica for UV transmission, water-free quartz for NIR.Custom fiber assemblies. Let us know your desired spectral transmission range, core and bundle diameter and fiber length. We provide 6, 8, 12+ into 1 termination for imaging spectrometers as well as specialty coherent fiber manifolds that split and terminate images into smaller selected channels to multiplex spectral or spatial coverage.
