AlphaBright QTH VIS-NIR Light Source

Click Here for a PDF About AlphaBright QTH VIS-NIR light Source

Broadband scientific light source for scientists and engineers needing intense VIS-NIR light coupled through an optical fiber. The AlphaBright design also ensures light remains efficiently focused on the optical fibre cable when optical filters (available as accessories) are inserted into the filter holder.

AlphaBright is much brighter than alternative designs making it the ideal choice for
applications requiring an intense VIS-NIR light source. AlphaBright increases the proportion
of light entering the optical fibre by positioning a plano-convex lens at its focal length from
the end of the optical fibre cable. To direct even more light towards the optical fibre cable, the AlphaBright also contains a convex mirror positioned behind the bulb.

By directing brighter light onto the sample signal to noise ratio is improved and ultimately the reliability of measurement data. AlphaBright offers real advantages for experiments involving measurements from a distance or analysis of poorly reflecting materials.

The power supply has been chosen for its stable output ensuring minimal light intensity fluctuations. The light source warms-up in 10 minutes after which time its intensity is stable to within 0.1%.

The unit arrives for immediate, optimal performance.
