Embodiment 1-20

[0029] The implementation method of embodiment 1-20 is as follows:

[0030] In embodiment 1-20, select Nb respectively 2 o 5 , HfO 2 、 Ta 2 o 5 、Al 2 o 3 or TiO 2 SiO 2 As low-refractive index material, according to the parameter design of embodiment 1-20 in table 1, table 2, table 3, table 4 and table 5 respectively, multilayer dielectric film reflection narrow-band separation filter combined device,

[0031] see figure 1 , figure 1 It is a schematic cross-sectional view of Embodiment 1 of the multilayer dielectric film reflective narrow-band separation filter combination device of the present invention. As can be seen from the figure, the present invention is constituted by sequentially including a first plane reflector 4, a first reflective cut-off filter along the incident direction of the light path. Light sheet 5, the second reflection cut-off filter 6 and the second plane reflector 7, the first described plane reflector 4 forms an angle of 45° with the inciden...

Abstract

The invention discloses a multilayer dielectric film reflection narrow band separating light filter combined device. The device is characterized in that the device sequentially comprises a first planar reflection mirror, a first reflection blocking light filter, a second reflection blocking light filter and a second planar reflection mirror along a light path incident direction, an angle of 45 degrees is formed between the first planar reflection mirror and an incident light beam, the first reflection blocking light filter and the first planar reflection mirror are oppositely and parallelly placed, the second reflection blocking light filter and the first reflection blocking light filter are oppositely and perpendicularly placed, the second planar reflection mirror and the second reflection blocking light filter are oppositely placed in a 45-degree angle manner, and each of a short-wave-pass reflection blocking light filter or a long-wave-pass reflection blocking light filter is formed by a multilayer dielectric film reflection blocking light filter. The multilayer dielectric film reflection narrow band separating light filter combined device reaches submillimeter radian in angular spectrum selectivity.

Description

technical field [0001] The invention designs an optical filter combination device, in particular a multi-layer dielectric film reflective narrow-band separation filter combination device. Background technique [0002] Laser has the characteristics of good monochromaticity, good coherence, good directionality and high brightness, which makes it a bright pearl in natural science. High-power lasers have been widely used in spectroscopic technology and optical measurement, and have become an important means of medical and health research and clinical diagnosis; they have great application potential in military technology, industrial production, and daily life. The development of laser devices is inseparable from optical devices. In the past half century, the development of electronics and communication technology has required the size of devices to be smaller and smaller. Therefore, the research on thin film materials has become a very important topic. [0003] In high-power sy...
