Problems solved by technology

However, there are still the following deficiencies: first, the positioning block has low precision, which cannot be used as a reference, and the splicing accuracy is low; second, the structural layout requires the filter to be glued before splicing, and the glue is easy to flow and pollute the working surface; Three, the pressing device has no movement reference, which can easily lead to uneven pressing force and poor consistency of the position of each surface after splicing

Abstract

The invention discloses an integrated optical filter splicing device, comprising a first concave block and a second concave block, the first concave block and the second concave block are bonded to form a concave structure, and Two vertical slots are formed at the bonding place; the width of the slot is less than or equal to the thickness of the filter, and the two sides of the filter can be inserted into two slots respectively from above the splicing device. In the slots, the slots can accommodate at least one optical filter in the vertical direction; screw holes are symmetrically arranged on the first concave block and the second concave block, and the screws pass through the holes. The screw hole is used to adjust the pressing state of the first concave block and the second concave block. The invention has the beneficial effects of high splicing precision of optical filters, high splicing efficiency, high working plane precision and good consistency.

Description

technical field [0001] The invention relates to the technical field of precision equipment preparation, in particular to an integrated optical filter splicing device. Background technique [0002] The integrated optical filter can filter rich spectral information, and can be integrated on a multispectral spectrometer to achieve a wide range of applications in meteorological research, precision agriculture, forest fire prevention, and coastal cruises. With the development of multi-spectral technology, it is difficult for existing splicing devices to achieve high integration and high-precision combination of multiple narrow strip filters. In order to meet the needs of fine multispectral users, the development of devices that can achieve ultra-high integration and high-precision narrow-strip filter splicing has aroused people's interest. [0003] The current splicing device has no precision requirements for the splicing benchmark itself, the splicing process is complicated, di...
