A.α-BBO Glan-Thompson prism B.Glan-Thompson prism
Features/Functions
Constructed of two Icelandic stones or α-BBO crystals glued together, it has a better extinction ratio than air-gap granau, and has a very large field of view. The field of view depends on the ratio of length to aperture , the current standard L/A is 1.6:12, the value is 5:1 and 3.0: Ge Thomson has a very wide use band α-BBO prism can be used for 220~900nm, Iceland stone prism can be used for 350~2300nm.
