Various Filters

Selecting wavelength
Conductor easily controls and selects colors.

Light does not consist of visible rays only and ranges widely from long-wavelength infrared to short-wavelength (... deleted) ultraviolet. Dichroic filters and mirrors can select a specific wavelength band from the light only. High transmittance in transmission area with little ripple. Small mesial magnitude.

Consistent color tone even with variation in temperature.
Filters for bright colors maintain consistency even under temperature fluctuations.

Some civil equipment is equipped with liquid crystal vision with a high-intensity metal halide light source and is very useful for reproducing bright images on a large presentation screen.

Spectral characteristics remain unchanged even in a vacuum or under high temperature conditions. High transmittance in transmission area with little ripple.

Protection lenses for temperatures as high as 500°C.
Sunglass protection lenses. Important "eyes" for filtering out information.

Bubbles or cracks occur in lenses exposed to high temperatures, resulting in the lenses breaking. This heat resistant filter protects lenses from higher temperatures. Continuous 24-hour use at 500°C is guaranteed.

Catching the phenomena using only infrared rays
Infrared remote control and more simply by applying infrared rays for optical control.

Separating RGB, the three primary colors.
3CCD prism system separation supports excellent color rendering and resolution.
