Method.
Background technique
CCM refers to camera module, is a kind of core devices for various novel portable picture pick-up devices；It is mainly used in
The fields such as mobile phone, laptop, tablet computer, smart home, vehicle-mounted, VR/AR and security monitoring, with traditional camera system phase
Than having many advantages, such as miniaturization, low power consumption, low cost, high image quality.
The imaging process of camera is exactly by the digitized process of optical signal.Light passes through camera lens first, reaches photosensitive member
Part may be CCD or CMOS, and the effect of the two is all to convert light into digital signal, and then digital signal is transmitted
To a special outer reason device (DSP), be transferred to after picture signal enhancing and compression optimization again mobile phone or other deposit
It stores up in equipment.Camera module is mainly by camera lens (lens), sensor (sensor), back-end image processing chip (Backend
IC), four parts of soft board (FPC) form.The most important factor critical component for determining a camera quality is exactly: camera lens,
Optical filter, imaging sensor and digital signal processing chip.
On daytime, due to including visible light and infrared light in the light of nature, when these light enter video camera simultaneously
Camera lens, after being reflected by stationary lens, it is seen that light and infrared light will be in different target surface imaging, and visible light is imaged as colour
Image, infrared light are imaged as black white image, and infrared light will form the virtual image in this target surface, thus the color of influence diagram elephant and
Quality.
Cutoff filter is alternately to plate high low-refraction on optical base-substrate using precision optics coating technique
Optical film realizes that visible region (400-630nm) is high thoroughly, the optical filter of infrared (700-1100nm) cut-off.Infrared cutoff
Optical filter mainly has reflective and two kinds absorption: 1) reflective: to intercept infrared light using substrate plating IR rear surface reflection.Instead
Intercepting for infrared light can be easy to appear as biggish offset occurs for the variation of incident angle by penetrating formula cutoff filter
By the secondary imaging of reflected light, halation and ghost phenomenon are formed.2) absorption: to utilize the light absorption object being dispersed in baseplate material
Quality Control lambda1-wavelength absorbs infrared light and visible light is allowed to pass through.Currently, the substrate that absorption optical filter uses is usually
Smalt, i.e. phosphate glass or silicate glass, surface still need to plating IR, and effect is the transmission for further decreasing infrared light
Rate.It is necessary in the optical design of pick-up lens in the case where high-end intelligent use market requires more and more thinner trend to camera module
The incident light for receiving greater angle causes the bad phenomenon of conventional reflective IR optical filter more obvious.Absorption smalt IR
It has clear improvement to colour cast existing for reflection optical filter and ghost problem, the softer nature of Photograph image color of shooting.
The traditional infrared edge filter IRCF technological process of production is using Germany's Xiao Te D263 glass substrate by large stretch of
Cutting, ultrasonic cleaning, vacuum evaporation, small pieces cutting (may include round as a ball processing), finished product ultrasonic cleaning, product surface inspection
The processes such as test.This traditional handicraft has the problems such as operating procedure is more, entirety yield is not high, production capacity is by restricting.Wherein, ultrasonic wave
Cleaning and vacuum evaporation process are affected to IRCF product surface finish.With the expansion and industrial grade in the market IRCF
Promotion, to product surface require it is higher and higher, some medium and small plated film enterprises be unable to satisfy high-end market requirement, for this purpose, we
