Description

For some measurements, a reflection probe is needed that can be coupled to two spectrometers and a light source. A good example is a reflection measurement in the UV/VIS and NIR range. For these situations, Avantes offers our reflection probes with multiple legs. The light from a light source is coupled into a fibre bundle, consisting of 17 illumination fibres which transport the light to the end of the probe. The reflected light is uniformly reflected into the two read fibres, each of which is connected to a spectrometer. For measurements under a 90° angle, the FCR-90-Option has been developed. It is an adapter with a mirror mounted at 45° and can be easily mounted to the tip of these reflection probes. To accurately focus a small measurement spot from a higher distance, the FCR-COL adjustable US/VIS/NIR collimating/focusing lens is available and can be mounted to the tip of these probes. Technical Data Fibers - 19 fibers 200 µm core, 17 light-fibers, 2 read fibers in 2 separate legs, N.A.= 0.22. Standard 2 m length, splitting point in the middle Wavelength range - 200-2500 nm (UV/VIS/NIR) Connectors - SMA-905 connectors (3x) Probe end - Stainless steel 316 cylinder, 50 mm long x 6.35 mm diameter. Optionally –PK for PEEK or –HY for Hastelloy® C276 (on request) Jacketing - The optical fibers are protected by a silicon inner tube and a flexible stainless steel (BX, O.D. 6.0 mm) or chrome plated brass (ME, 5.0 mm) outer jacket. The jacketing also provides stress relief Temperature - -30°C to 100°C. (-HT version 200°C) Bending - Minimum bend radius: Short term (few seconds) 20 mm, long term: 120 mm
