RTS20x Series Raman Zoom Lenses This series of lenses is equipped with long working distances from 20 mm to 6 meters, which expands the utility of our BAC100/BAC102 fiber optic Raman probes to measure in places that may be inaccessible to a standard probe. The lenses have adjustable working distances and provide a wide zoom, and even telescopic measurements, with various models available, each optimized for different Raman excitation ranges. The long working distances allow Raman Accessory for process monitoring behind optical glass such as glass vacuum chambers, and analysis of samples in difficult-to-access places such as may be found in archaeological sites. The model with working distance up to 6 meters allows for stand-off measurements such as needed for energetic materials. The lenses can be mounted on a tripod (optional) using a standard ¼”-20 thread mount. These lenses have a working temperature range of -30°C to +50°C. Applications: • Stand-off measurements of energetics • Process monitoring through thick-walled glass reactors • Noncontact high temperature, high pressure measurements • Archeological measurements in ruins, buildings and other structures • Noncontact measurement of art works Specifications: Model Name Suitable Raman Working Distance Aperture Focused Laser Spot Excitation Range (adjustable) Diameter Diameter RTS200-VIS-NIR Zoom Lens 20 – 60 mm 500 – 850 nm 20 – 60 mm 23 mm ~0.21 mm @ 20 mm RTS200-NIR Zoom Lens 20 – 60 mm NIR 785 – 1064 nm ~2.3 mm @ 60 mm RTS201-VIS-NIR Zoom Lens 60 – 600 mm 500 – 850 nm 60 – 600 mm 48 mm ~0.22 mm @ 60 mm RTS201-NIR Zoom Lens 60 – 600 mm NIR 785 – 1064 nm ~2.6 mm @ 600 mm RTS202-VIS-NIR Zoom Lens 0.6 – 6 m 500 – 850 nm 0.6 – 6 m 70 mm ~0.6 mm @ 0.6 m 8.5 mm @ 6 m Dimensions: RTS200: RTS201: RTS202: 19 Shea Way, Newark, DE 19713, USA • Tel: +1 (302) 368-7824 • Web: www.bwtek.com Copyright 2017 B&W Tek · Doc-Rev: 280001280-A (2017/05/03)
