Description
Technical Field
The invention relates to a broad spectrum reticle containing a laser point source, belonging to the technical field of optical measurement.
Background
The reticle is an important accessory in many optical instruments, and can realize basic functions of marking and positioning a target, facilitating observation and the like. In many optical instruments, reticles play an important role. In the prior art, reticles are often used with optical imaging devices (e.g., CCDs) to improve the measurement accuracy of the instrument.
In the patent publication "CN 206610024U" with the patent name "a wide spectrum reticle", the substrate of the reticle is made of common glass, the center of the upper surface of the substrate is carved with a reticle cross, and a conversion coating capable of converting visible light into infrared light is arranged at the concave position of the reticle cross. When the illumination light source is turned on, for an infrared test or observation instrument, the substrate of the reticle is dark, and the differentiation cross is bright; for visible light testing or viewing instruments, the reticle substrate is bright and the reticle cross is dark. Thus, the reticle can be used as a reticle for both visible and infrared light testing instruments. The disadvantage of this reticle is that it can only be applied to the imaging optical system and not to the energy receiving system when it is necessary to provide the same target for calibrating the imaging optical system and the energy receiving system. The reticle is provided with a light splitting path and a confocal plane, and the light splitting path and the confocal plane are respectively arranged on different mechanical structures, and the light splitting path and the confocal plane are coaxially adjusted when the reticle is used, so that the complexity of the mechanical structures is increased, one of the light splitting path and the confocal plane deviates from the original position due to the influence of temperature and vibration in transportation or use, the focal plane deviates and confocal imbalance is caused, and the later installation and adjustment difficulty is increased.

Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings and examples.
The first embodiment is as follows:
as shown in fig. 1 and 2, a broad spectrum reticle containing a laser point source, comprising: the optical fiber comprises a metal circular sheet 1, a ground glass circular sheet I2, a ground glass circular sheet II 3, a glue layer I4, an optical fiber 5, a glue layer II 6, a ceramic core 7 and a glue layer III 8. The metal circular sheet 1 and the ground glass original sheet I2 are adhered together, the ground glass circular sheet I2 and the ground glass circular sheet II 3 are coaxially arranged in parallel, and both the metal circular sheet and the ground glass circular sheet are made of ZnS materials capable of passing visible light and infrared light simultaneously. When the light source is started to illuminate on the right side of the ground glass wafer 3, the ground glass wafer II 3 and the ground glass wafer I2 are used for carrying out light uniformization on the light source in sequence, and therefore illumination is more uniform. The optical fiber 5 sequentially passes through the ground glass wafer II 3 and the ground glass wafer I2 and is positioned on the central axis of the ground glass wafer II and the ground glass wafer I. The ground glass circular sheet II 3 is fixedly bonded with the jacket layer 5-2 of the optical fiber 5 through the glue layer I4. In addition, as shown in fig. 1, in order to avoid the deviation of the outgoing direction after the light passes through the optical fiber 5, a ceramic core 7 is sleeved on the outer part of the optical fiber core 5-1 of the optical fiber 5, and the two are glued by a glue layer two 6. The ceramic core 7 and the ground glass wafer I2 are glued by a glue layer III 8.

And scribing cross lines are engraved in a bright line etching mode at the central position of the metal wafer 1, and meanwhile, the ground glass wafer I2 is used as a substrate to jointly form a wide spectrum reticle.
In order to realize the centering work of the end surface of the optical fiber core 5-1 and the metal wafer 1, the bonding is carried out under a high power microscope, the metal wafer 1 is moved slightly, and the center position of the end surface of the optical fiber core 5-1 is adjusted to the center position of the cross on the metal wafer 1, as shown in fig. 2; in order to prevent the optical fiber 5 from moving in the using process, the optical fiber 5 needs to be fixed in an adhesive mode between the jacket layer 5-2 and the wool glass wafer II 3 of the optical fiber 5, between the ceramic core 7 and the optical fiber inner core 5-1, and between the ceramic core 7 and the wool glass wafer I2 to respectively form a glue layer I4, a glue layer II 6 and a glue layer III 8, wherein the thickness of the glue layers of the glue layer I4, the glue layer II 6 and the glue layer III 8 is about 8-13 mu m, and the glue layers are all double-component epoxy low-stress glue. In addition, in order to ensure that the point light source formed by the transmission of the laser through the optical fiber 5 and the reticle are on the same focal plane, the ceramic core 7 needs to be moved slightly so that the left end face is flush with the left side face of the metal wafer 1, as shown in fig. 1.
The illumination light source can be a bromine tungsten lamp with the wave band range of 0.4-14 mu m.

The optical fiber 5 sequentially passes through the ground glass wafer II 3 and the ground glass wafer I2 and is positioned on the central axis of the ground glass wafer II and the ground glass wafer I. And scribing cross lines are engraved on the metal wafer 1 in a bright line etching mode, and meanwhile, the ground glass wafer I2 is used as a substrate to jointly form a wide spectrum reticle.
In order to realize the centering work of the end surface of the optical fiber core 5-1 and the metal wafer 1, the bonding is carried out under a high power microscope, the metal wafer 1 is moved slightly, and the center position of the end surface of the optical fiber core 5-1 is adjusted to the center position of the cross on the metal wafer 1, as shown in fig. 2; in order to prevent the optical fiber 5 from moving in the using process, the optical fiber 5 needs to be fixed between the jacket layer 5-2 of the optical fiber 5 and the wool glass wafer II 3, between the jacket layer 5-2 of the optical fiber 5 and the optical fiber inner core 5-1, and between the jacket layer 5-2 of the optical fiber 5 and the wool glass wafer I2 in an adhesive manner to respectively form a glue layer I4, a glue layer II 6 and a glue layer III 8, wherein the glue layers of the three are all about 8-13 mu m in thickness and are all double-component epoxy low-stress glue. In addition, in order to ensure that the point light source formed by the transmission of the laser through the optical fiber 5 is on the same focal plane as the reticle, the optical fiber 5 needs to be moved slightly so that the left end face of the optical fiber 5 is flush with the left end face of the metal wafer 1, as shown in fig. 3.
