UV/VIS/NIR Collimating Lens Lens Diameter:6mm The special WS-2-GEM is designed

The special WS-2-GEM is designed to facilitate holding and cooling a gemstone with liquid nitrogen

The material offers long term stability

They are constructed using high quality Silica/Silica fibre with Polymide buffer

These bifurcated fibre cables are suitable for use over 200-1100nm

but it should be noted that prolonged exposure to DUV wavelengths will cause attenuation from 200-250nm which will increase further over time

UV/VIS/NIR Collimating Lens Lens Diameter:6mm The special WS-2-GEM is designedThe collimating lenses screw onto the end of SMA905 terminated optical fibres and convert divergent beams of light into parallel beams. Collimating lenses can be used in any optical setup that require parallel beams of light at the illumination source and or at the entrance optics. There is also a version used to focus the exit light under 90. Full technical details on all our collimators and collimating lenses can be found by clicking here.
