Manual film wave plate drawing machine and method for manufacturing wave plate by using thereof

Abstract

The invention relates to a manual film wave plate drawing machine, comprising a manual drawing film vertical frame unit, a delay measuring system device and a mobile baking device, wherein a single-color light source, a collimating lens and a polarizer of the delay measuring system device are positioned at the front part of the film vertical frame unit; the baking device is positioned at the rearpart of the film vertical frame unit; and a quarter of wave plate of the delay measuring system device and the time interval of an analyzer are inserted between the baking device and the manual drawing film vertical frame unit. A method for manufacturing the wave plate comprises the following steps: firstly, respectively soaking a plastic film in distilled water and boric acid solution, by stabilization of the single-color light source, arranging the graduation of the polarizer at 'zero position', arranging the analyzer at the position of the target delay graduation, and simultaneously, removing the baking device; and flatly placing the processed plastic film on the flat surface end of a device for loading a clamping shaft for clamping tightly, rotating a hand wheel with the same speed, when the eyes observe that the field of vision becomes darkest, locking the hand wheel, returning the baking equipment for baking and obtaining a finished product of the wave plate.

Description

technical field [0001] The invention belongs to the manufacturing technology in the field of optics, and in particular relates to a manual stretching machine for thin film wave plates and a method for making wave plates with it. Background technique [0002] Waveplates are one of the most basic and widely used optical components in the field of polarization optics. For the monochromatic wave plate, it is mainly made of two materials, one is a birefringent crystal material and the other is a plastic film. Compared with crystal wave plates, plastic thin film wave plates are more and more popular because of their large aperture, small delay variation with incident angle and temperature, and low material cost. But its application situation is not satisfactory. At present, there is no domestic manufacturer that can provide plastic wave plates, and only one or two manufacturers in Japan and the United States are making plastic wave plates abroad. The reason is that its manufactu...

AI Technical Summary

Problems solved by technology

At present, there is no domestic manufacturer that can provide plastic wave plates, and only one or two manufacturers in Japan and the United States are making plastic wave plates abroad. The reason is that its manufacturing process is very complicated, and it is affected by temperature, humidity and film during processing. Affected by various factors such as tension, the use of mechanized mass production, on the one hand, cannot strictly control the wave plate delay during processing, and the product accuracy cannot meet the use requirements in many occasions, which limits the application range of the product; on the other hand On the other hand, it is impossible to provide wave plates with arbitrary delays according to user requirements
