Filters corresponding to the light absorption spectra of chlorophyll a and chlorophyll b.
The IR Cut Filter 3 is a dielectric multilayer film that does not transmit infrared light (reflects it) while allowing visible light to pass through. It is formed by ion-assisted deposition (IAD), creating a shiftless and dense film. Compared to IR Cut Filter 1, it is a wide transmission range IR cut filter that allows visible light to pass close to the near-infrared region. Additionally, it features an anti-reflective coating (AR) on the backside, enhancing the transmittance in the transmission range. It is capable of transmitting and reflecting not only visible light and infrared but also any wavelength as needed. This filter corresponds to the light absorption spectra of chlorophyll a and chlorophyll b, making it suitable for plant growth experiments. We provide consistent design and manufacturing of IR cut filters. We will design and manufacture according to customer requests, including specifications for half-wavelength, transmission band, and cut-off band.
