Spectrum measuring fixture

Abstract

The invention relates to a spectrum measuring device, comprising a fixing board of which the center is provided with a circular first loophole; an arrangement board provided with a plurality of circular containing holes of different sizes while each containing hole is provided with a containing part and a second loophole at the bottom center of the containing hole and the aperture of the second loophole is little smaller than the diameter of the containing part; and a luminous flux screen provided with a plurality of third circular loopholes of same number of the containing holes while the third loopholes are corresponding to the containing holes one-to-one and the aperture of each third loophole is little smaller than the diameter of the containing part. The fixing board is respectively connected with the arrangement board and the luminous flux screen. The arrangement board and the luminous flux screen can be rotated to align the centers of the first loopholes, the third loopholes and the third loopholes corresponding to the second loopholes.

Description

technical field [0001] The invention relates to a spectrum measuring fixture. Background technique [0002] Modern optical films have pivotal applications in various fields, such as IR-Cut Filter, etc., which are used in mobile phone cameras, digital cameras, digital cameras, computer cameras, security monitor (CCTV) cameras, CCD (Charge Coupled Device, Charge Coupled Device) digital imaging system or CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) digital imaging system such as videophone and video doorbell can effectively improve the influence of infrared rays on CCD / CMOS imaging, Prevent CCD / CMOS image sensors from producing false colors and moires, improve the effective resolution and color reproduction of color CCD and CMOS image sensors, please refer to the paper HDTV single-chip CCD color camera published by Tanaka, T. et al. on IEEE in 1990 , Consumer Electronics, IEEE Transactions on Volume 36, Issue 3, Aug 1990 Page(s): 479-...

AI Technical Summary

Problems solved by technology

The practice of using this jig to measure first and then cut and round the product cannot accurately and effectively control the quality and performance of the product, and the accuracy of measurement is low. Therefore, in order to improve the accuracy of product quality measurement, It is necessary to measure the product directly, but the size specifications of different batches of products are different, and the general jig has fixed receiving holes. When measuring small-sized products, the inconsistency of the size will reduce the accuracy rate, and it is easy to Light leakage occurs at the edge of the optical film, causing measurement errors
