Projector filter
Nowadays, people have increasingly high demands for quality of life. We need the atmosphere of eating and the intelligence of our homes, even the traditional entertainment projects that began to be popularized in China in the 1980s; — Watching TV has also been challenged. Yes, the rapidly developing home projectors in recent years have shaken the position of traditional television. Do you know the principle behind projectors, which are ubiquitous in daily life?
The projector first illuminates the image display element with light to generate an image, and then projects it using a lens. The image display components of a projector include the transmission type of the image generated by light transmission and the reflection type of the image generated by reflected light Regardless of the type used, the light of the projection lamp is divided into three colors: red, green, and blue, and then produces images of various colors. Due to the fact that the element itself can only be displayed in a single color, three components will be used separately to generate the three color components. Then calmly combine the three color images into an image, and finally project it onto the screen through the lens.
In traditional projectors, it is necessary to separate light sources, merge light beams, change the optical path, use optical filters, use dichroic mirrors to separate the light sources into the three primary colors of RGB, and then merge and transmit them. High performance reflection is also required when changing the optical path length, all of which are collectively referred to as micro projector filters.
The specialized filters for micro projectors include: anti blue, anti red, anti blue, anti red, anti green, anti blue, and mirror.
Multiple uses of projection filters:
1. Used in digital camera lens systems and digital cameras, its main function is to prevent CCD image sensors from producing false colors and ripples, and improve the impact of infrared on CCD imaging.
2. Projection optical components
Advantages: Good stability, high surface smoothness, and accurate wavelength positioning.
Application areas: Used for projectors, projection televisions, etc.
3. Other precision optical filters
Usage: Security systems, stage lighting, scanning instruments, microscope analysis imaging systems, prism spectrophotometry, CD/DVD optical lenses, mobile phone windows, infrared sensors, laser reflectors, light windows, laser protection, surface extinction, and protection of optical lenses and their components.
