Specific embodiment
Below in conjunction with attached drawing, the present invention is described in further detail: the present embodiment is being with technical solution of the present invention Under the premise of implemented, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
As depicted in figs. 1 and 2, a kind of involved in the present embodiment to be filled for the active absorption body that wavelength is 1053nm light wave It sets, comprising: bottom plate 1, trough of belt side plate 1, the uviol plate 5 of side plate 4, two of trough of belt side plate 23, two and two fused quartz glass Glass plate 6, two side plates 4 are symmetrically fixed on bottom plate 1, and one end of two side plates 4 is fixed with trough of belt side plate 1, two side plates 4 The other end be fixed with trough of belt side plate 23, bottom plate 1, trough of belt side plate 1, trough of belt side plate 23 and two side plates 4 constitute a boxes Body, two uviol plates 5 are symmetrical, are in the shape of the letter V and are inserted into trough of belt side plate 1 and trough of belt side plate 23, each uviol The upper surface of plate 5 is equipped with a fused quartz glass plate 6, and two fused quartz glass plates 6 are also V-shaped, two V-shaped fused quartz glass Angle between plate 6 is 30 °.
The fused quartz glass plate 6 with a thickness of 1mm.
The material of the bottom plate 1 is aluminum oxide.
Between trough of belt side plate 23 and side plate 4, between bottom plate 1 and trough of belt side plate 1, between bottom plate 1 and side plate 4 by spiral shell Nail 7 is fixedly connected.
Fused quartz material has higher light transmission to infrared entire spectral band ultraviolet, but incident light wave length becomes When change, the optical performance parameters such as transmissivity, refractive index of material are variant, such as Fig. 6 of curve when refractive index is with wavelength change Shown, when wavelength 1053nm, 527nm and 351nm, refractive index n is respectively 1.450,1.461 and 1.475.
