OPTICAL DETECTION SYSTEM FOR MONOCHRAMATIC BEAM GONIOSPECTROPHOTOMETRY (PP01, Pages 163-166)

Click here to purchase
The design and manufacture of a detection system suitable for an ‘underfilled sample’ goniospectrophotometer system illuminated by a quasi-monochromatic beam is described and assessed. Optomechanical design of the detection system was optimised to ensure equal efficiency for both vertically and horizontally polarized light. To achieve this, a mirror tilted about both vertical and horizontal axes is used to focus light into a custom made sintered halon integrating sphere. Photon detection is performed by a combination of a state-of-the-art small factor photon counter and a Si based detector in conjunction with custom made switch integrator low noise electronics. This hybrid detector covers ten orders of magnitude of linear operation.
