Depolarisers

• Thoroughly scrambles a polarised beam to make it appear unpolarised
• Available in both single and double wedge configurations
• Made from the finest optical quality crystalline quartz
• Single wedge form has transmission from 180nm to 4500nm
• Mounted in metal ring for convenience

These quartz wedges scramble the polarisation of an impinging beam of light and render it substantially depolarised. We offer a single wedge and a double wedge. The single wedge introduces a deviation in the beam of light. By cementing two wedges together it is possible to reduce the beam deviation to less than 10arcmin. However, this is achieved at the expense of broad band transmission since an index-matched optical cement must be used. Both types are 17mm square and are mounted in a 30mm diameter metal cell.
