The T-RP28 and T-RP29 reflection probes feature a spectrometer leg with a linear bundle configuration for improved coupling efficiency with our compact spectrometers. The linear bundle end matches the shape of the entrance slit better than a single fiber or round bundle configuration, increasing the amount of light entering the device (see the Round vs Linear Leg tab for more information). This is ideal for samples that are sensitive to light exposure or heating caused by absorption. The light source end consists of a single fiber; this can be useful when a sample's exposure to light needs to be minimized.
When plugging the linear end of the bundle cable into the spectrometer or other device, the fiber array must be aligned with the entrance slit. For ease of alignment, the fiber array's axis is indicated by a line on the connector sleeve, as shown to the right. Precise alignment of the bundle and slit is not critical, but misalignment of more than ±5° can cause a reduction in signal strength. In order to maximize signal intensity, we recommend rotating the bundle while monitoring light levels in the spectrometer; once optimized, tighten down the threaded portion of the SMA connector to lock the bundle in place. When using these bundles with our CCD Compact Spectrometers, the fiber array should be oriented vertically.
Each connector is engraved with the fiber output configuration in that leg.
