Method and assembly for gas detection via a convergent birefringent filter |
摘要 |
An assembly and method provide sensitive high speed spectroscopic gas detection via the use of a non-collimated convergent light path through a birefringent crystal in a birefringent filter design to allow improved light collection and a reduction in the number of optical elements required to produce a useful absorption signal for the detection of gases.
